Can a car fix itself? Nissan ABS- (SI Ep. 13.3)

[@HUBBABUBBADOOPYDOOP]

Swaptronics can remedy problems- just by manipulating plugs, harnesses, modules. Pin fitment due to corrosion, temperature changes, morning connectors are cold, condensation, etc. Engine heat dries and warps plastic and tiny copper pin sockets. Investigate every lead in all plugs- there's a Gremlin in there, you'll be seeing this car again. Don't forget- green crusties + salt air can= CONDUCTORS instead of insulators like we're used to. A pothole filled with Winter road brine, splash up on connectors, can conduct and/or insulate micro voltages.

[@smms1276]

WELL SAID 👍

[@PineHollowAutoDiagnostics]

yup so many variables, and so many intermittents!

[@lo0ops]

I watched this and agree it's a puzzler but today, next day, I feel unfulfilled that there's no conclusion. I have to know the root cause! Thanks Ivan I'm a big fan of your work.

[@jannepo]

Since you do not know either, I speculate some. What if the fault was not around the ABS at all? The last device in the CAN line is AC/dash meters and audio. ABS and those died and communications were messed up. ABS is the device on that CAN line just before the 120 ohm terminator in the AC/Dash (should be there as it is the last device on the line). If there is a intermittent termination in the dash, the CAN signal will be reflected from the end of the wire, back to the line. ABS module might be just far enough from the end of line so that the incoming and refleted signals cancel each other at that point of the wire. ABS see this as a vacant CAN line to transmit and when it transmits it messes up the communications in the line. This also means that you have either no comm on random comm with ABS unit. There is no fault in ABS unit itself but in the CAN bus. When the ABS is unplugged it does not disrupt the communication in the line by sending over the traffic, it itself does not see in the line but others which are not in the point on wire where incoming and reflected wave cancel each other out see two nodes sending at the same time and fail comms We oldies know this from the "thin ethernet". Unplug the 50 ohm terminator and some PC:s continue to work, but some PC's located at the reflection points where waveforms cancel each other are "blind" and send as they see the line vacant. -> what if the problem was a faulty termination in the dash? ww2-secure.justanswer.com/uploads/DoritoWhatz/2010-09-09_125657_New_Picture_2.jpg

[@PineHollowAutoDiagnostics]

Wow Janne, thank you for the detailed hypothesis! Anything is possible, I suppose. If the car was at my shop, I would definitely do a deeper dive diagnosis on it and get to the root cause.

[@jannepo]

Yep. If you had the car, you could plug in a multimeter and check out that there is a constant 60 ohm on that line. Or use Pico scope CAN protocol diagnostics. If you get a messed up comms at the ABS conector, it is a score & home run.

[@ericcorse]

This Maxima has entered the Twilight Zone. The old folks will know what I'm talking about.

[@billrimmer5596]

Plugging unit in and out several times may have done the trick. When does the K-line ever communicate? Only when a problem occurs? Full time job?l Weekends with Keith? Your heart is in advanced automotive diagnostics😀

[@PineHollowAutoDiagnostics]

Hey Bill! I took a vacation to diagnose some cars and hang out with Keith. It was awesome :D

[@RobertHancock1]

The K-Line may just be for scan tool communication. I've seen some cars that are set up that way for whatever reason.

[@ablackformula]

At one point in the video I saw the k-line fluctuating. Was curious if ac-coupling would have shown some communications over the voltage line. Either Eric O, Ivan or ScannerDanner had a video of an abs wheel speed sensor that communicated with ac-coupling.

[@throttlebottle5906]

K bus should be nearest "zero volts" to "near battery voltage" it's low speed serial data and I didn't see it change significantly, but I wasn't watching like a hawk, it woulf have to change more than half voltage to make a "binary bit" change. think of "morse code" a light buls or tone full "on/off" like when the older cars flashed the check engine light for code retrieval (old ford's using an analog volt meter)

[@AutodiagnosticoDetroit]

good video friend! but in my opinion, it may be that you have an ignition coil or a spark plug out of specifications and put the electrical noise in the communication line of the ABS module. best regards

[@kbrx4310]

Bet anything it's the pcm/module grounds...I've fixed the same issue on many many many nissans especially the altima and maxima's... its pretty well documented too when they start throwing comm codes there's a few grounds on the core support and a few on the dash frame that are always corroded and causes it to lose communication intermittently with all control modules on Can.

[@PineHollowAutoDiagnostics]

Great tip!

[@juanrodriguez-ry6yt]

basics that makes sense

[@charlemagne1162]

Is the alarm spliced into comm sys?

[@Mickey_Bauer]

Could this cause intermittent starting issues like click no crank (04 Maxima, manual 6spd)? I've tried a new starter and a new battery to no avail. I also replaced the main grounding/battery cable and my car drives strong like i got 50hp back and my fuel economy improved by 3mpg but it didn't fix intermittent starting issues. (I do have some kind of alarm installed by the dealership when the car was new)

[@kbrx4310]

Yes and no Mickey, if the car has a neutral switched starter relay from the pcm then yea I could see it causing a no crank or intermittent , if it was auto also yes it wouldn't know it was in park and would likely not crank ..however in your case its more likely you have an issue with the solenoid trigger wire or starter relay itself, perhaps a bad relay contact inside the relay not completing the circuit.

[@embreesmith7613]

thanks for taking the time to post this ..sad, but this kinda work requires much more knowledge than you day job that is paying $$ more :(

[@aquatrax123]

I would check to see if the aftermarket alarm is spliced into the CAN network. Some alarms communicate directly to the body modules to lock/unlock door ect..

[@steveo782812]

Makes you wonder since he showed the CAN wakes up when the button is pressed.

[@charlemagne1162]

I agree. I posted b4 i read yours. My 1st guess

[@ptrck6]

@ivan. I ran into the same problem on a escape hybrid. I replaced the whole abs unit $7000. Found out it was a power to the abs had 12v and a good ground. However the power wire wouldn’t hold any current to the abs. A new wire inlay from fuse box to abs cured the problem. Pinpoint the power and ground for current drop. Good luck bud

[@PineHollowAutoDiagnostics]

I checked powers and grounds with my 5A test light...nice and bright :)

[@aday1637]

[@Paul1958R]

[@hutchcraftcp]

I've had two nissans in the past. a Stanza, and a Sentra, both suffered electrical failures. cars would shut down randomly, replaced computers, had wiring traced...got rid of both. never bought another one.

[@PULSARGT]

This is a common problem, it is the headlight bulb fluid is low however, rarely it might be the flux capacitor :)

[@kennypatrol2zero616]

That was a hard one, so maybe a shorted out wire chaffing and with all the movement its had, its now not touching, you were not happy, but with all guys some food brought the smile back to you face, now go and do an Eric'O and get some Ice cream, you earned it, nice video

[@dcyres]

Ivan, should I flush/change break fluid on Nissan every 2 years as dealer “recommend”? Interested to hear your recommendation. Can make a video on how to change break fluid for first timer? Thanks!

[@SmittySmithsonite]

It's ones like this that make me question my career choice, lol! So frustrating to chase something for an hour or more, and then have the issue suddenly disappear - it's magic! HAHAHA! Oh, man what a horror show! I guess it must have been a pin issue - either fitment, or a bad connection between the wire & pin, and by unplugging it & plugging it back in, it created a good connection again. Or, something going on with the aftermarket alarm. Better you than me, Ivan! I'd be so frustrated there's no way I could shoot a video - it would be wall-to-wall expletives, LOL! I have a feeling we'll be seeing a Part 2 on this one ... ? 😉

[@chungaleta1234]

Set of plugs and wires and you're good to go. Trust me on this one LOL Great case Ivan, would like to see some follow up if possible.

[@Nando_989]

@10:30 fuel level circuit low or open code. Had that code come back even after a new pump. Almost changed the cluster. Remember the car monitors the fuel consumption so even though the gas gauge is correct the ECM is reading fuel level and fuel consumption and vehicle speed from your com. To give you the luxury or knowing your average mpg and average speed and miles until empty. That code came back instantly. With all that corrosion under the hood anything is possible.

[@ojjenkins7110]

I guess it was a Gremlin from the Kremlin. Dobro utra Ivan :-)

[@richreid2338]

2004 Maxima. Random ABS activation is usually from improper (not missing) rear abs sensor signal. Rear hubs corrosion covers the tone ring with rust dust. Can problem is separate issue, all can runs through meter\ac amp. Mounted just below the screen on the dash. Coins stored by the screen will fall into the meter ac amp and corrupt the can system. The coins move when you drive, creating the intermittent can problem.

[@ednewell1847]

I said the same thing about the a/c amp, did not see you already called it out

[@tracydiller4492]

Could be anything hell could be another senser just like them sensers that use a 5 volt reference one bad senser can cause the 5 volt reference to be pulled down. Good luck with this one Ivan.

My bride came with a Pontiac LeMans. It leaked oil all over the garage floor - a pool of oil. But since it was winter I figured fix it in spring, Come spring - no oil leaks. With a loud poof it blew the cover off the interior fuse box. Problem found - none, put the lid back on. The engine developed a bad miss. I was all set to pull the rear head when it went away. We gave the car away. Before it was picked up somebody slit a tire. Parked at the curb in front of its new home it was hit head-on and totaled.

[@throttlebottle5906]

sounded like an insurance scam story unfolding :)))

[@PineHollowAutoDiagnostics]

Wow what a story! I remember the Pontiac LeMans cars running around in the 90s. Looked kind of French lol

[@lorrinbarth1969]

I know it wasn't a Daewoo, it was a large sedan. I had to go look at some car pictures. It was a not a LeMans but instead a six generation Grand Prix.

[@CubasAutomotive]

This is unfair! Lol. I don't like not knowing what the issue was! I agree with moving on, though, I would if in your shoes. I hope you get to revisit this car in the future.... Great diagnosis process!

[@PineHollowAutoDiagnostics]

Yeah I know exactly that feeling. On the other hand some cars I just want to forget lol!

[@Ahto42]

One thing to note is that this car had a sunroof. Nissan has one of the crappiest drain systems. Not all, but may 2000+ models have some sort of a filter at the end of the plug that goes thru the firewall under the dash. Some of the ABS connectors are behind the drivers and go drivers kick panels. When the sunroof drains are clogged, then some water/moisture can drip on the connectors and cause many problems.

[@rollandsicard1628]

I have worked on more difficult problems on aircraft electronics that the factory could not fix after having the aircraft back to them three times! Mitsubishi Turboprop, Learjet model 36 and brand new model 55 aircraft and new design VLF/Omega systems. Had the factory redesign the antenna coupler to get rid of ground loops causing signal interference. Many digital busses in Avionics. Unimaginable problems with electronics and systems. Conquered them all.

[@throttlebottle5906]

fire, burn it all and use cable pairs again ;)

[@2secondslater]

how did you get from lost communication to actuator tests? going with no comm and CAN codes and the dash dropping out I would be gravitating towards a power supply fault.

[@mrb1864]

Mmm got nowhere on this one ! Is it harness plug, is it something else in wiring for abs module :-/ Would of thought if minor pin issue then likely improved after owners swaptronics . Guess see how progresses as can waste hours on this sort of thing when got little go on . maybe it is self healing lol, had a subaru legacy like that, wasted hours in diagnosis and a towing fee and after my last off board test on ecu fault never occurred again ! assumed that pin issue at ...

[@michaelproust7891]

Could you explain the breakout box on the white board? Please.

[@bruceaugustine6486]

sounds like a connector issue.the green crusties? With all those keys i wonder if it is wearing out the switch and causing issues with the theft deterrent system.

[@5Dale65]

Check the powers and grounds on the module. Use some extensions for your test leads, so you can connect them to the scope inside the car. Then go drive it, and watch if something changes there. I bet one of the powers or grounds has loose connection and thus the problem manifests only sometimes.

[@Nando_989]

Something tells me the car will be back. I’ve had codes come up on my nissan for fuel level voltage low and speed sensor out of range. Also instrument cluster jumping all over and sometimes die. Hard shifting and limp mode intermediately. Did the whole swap thing and issue came back. After hours or research and wire wiggling it all came down to the engine ground wires. Cleaned the ground wires cleared the codes and they never came back. Scanner had me looking in the wrong direction the whole time.

[@jkbrown5496]

He didn't say what kind of test light he used to test powers and ground, but maybe the grounds need a higher load test? Something turns on that need more amps but can't pull them? Or pin corrosion was causing this and was improved by working the plug? Had a '86 Mazda brand new that would just die while driving down the highway. Literally had to restart it on the roll in heavy traffic. No clue at the dealer until a service bulletin came out for a ground wire on the computer.

[@Nando_989]

JK Brown The TCM and ECM and ABS module share the same ground. Mine was the ground on the cam cover (4cyl). I know the v6 is set up differently. Hope we get to find out what it was. I think removing the abs module fixed the issue because now the ECM and TCM have a better ground without the ABS module Hogging the ground. So basically 3 components have the same ground and are fighting to ground at the same point. If that point isn’t clean or secured, you will have one component or two act up. My hats off to you techs who do this everyday.

[@69buzzie]

nando 989 z

[@jkbrown5496]

nando 989 That ground certainly seems to be something to be looked at hard with a numerical voltage drop measured. When cars start seeming magical, grounds are the good place to look for where the pixies are acting up. Ivan responded in another comment, he used a 5 amp test light on the ABS ground. But as you intimate, what if a combination of the modules is intermittently trying to push more amps to ground and causing a brown out. Also, seems logical that the ABS would be wired to drop out first in a voltage drop situation leaving the ECM and TCM working.

[@ramdodgetruck]

Interesting just the same Ivan. Thanks for posting this.

[@MrCJF75]

Since the ABS system draws so much current, it will put a strain on the system since it’s also connected to the CAN? Weak ground or a 12V source is possible and opens once load is imposed by the ABS maybe? Just a thought! Great job!

[@ozzstars_cars]

That was a crazy one! Any update Ivan on how the car is performing these days?

[@ryckygeegarrigosa9128]

Thats a cool snapo. Tool, what model is it ? I would like to look into it. Thanks

[@sabergermd]

[@wyattoneable]

That was interesting indeed Ivan.

[@grettaheisenberg4214]

Ivan,in my practice I had a car that is very similar to behaved, lost communication with the scanner, hung oscilloscope, stalled spontaneously, triggered regular alarm. A lot of time has been spent. The reason was trivial as usual. Spark plugs were installed earlier by the owner without interference of the resistors, and there was a very strong interference on the network of the car

[@PineHollowAutoDiagnostics]

wow have never seen this before! Electronics can do very unexpected things :)

[@throttlebottle5906]

haha, non-resistor plugs and or solid wires, kill the whole neighborhood with RF noise and miles of DSL users, not to mention shut down the vehicle it's in, unless it has points!don't think that's the issue, unless plugs/wires very bad and leaking lots of HV into the other lines, which scoping directly would show. then again, what if it's riding some other line back to the dash cluster from say alternator or temperature gauge :))

[@willemstreutgers1154]

suspect a resistance in the network with AC and ABS connected, so clean all connectors in the network and use some petroleumjelly to avoid future prob's. Fault can be triggered by slightly low voltage at certain moments when there is a load in this specific network.. Check battery as well.

[@throttlebottle5906]

dielectric silicone grease is preferred, if none and hard up petroleum jelly :)

[@juanrobertovasquez3466]

Hey bro I really need your advice regarding my car 🚙 what would be the most obvious thing that can cause my Nissan Maxima 07 to just drive on 1 second and don’t go into higher gears won’t go past 30 miles

[@speralta1]

Probably an incorrect observation here - but it seemed like once you connected to the k-line to the scope via the break out box the problems stopped. Would that be accurate? Makes me think the problem is maybe not on the CAN bus or the ABS module... Maybe?

[@stevestacey5793]

Super interesting problem! Would be cool to grab several seconds worth of hi res pico data (e.g. 500ms/div and max no of samples you can get) to be able to scroll through and see any short disturbances. I have seen weird things happen when 1 module has a bad connection on one of it's CAN lines, so everyone else on the network can communicate fine, but the module with the bad connection occasionally detects a corrupted message and reacts by sending an error frame, which can then upset the rest of the network which would otherwise have been fine. Looks like the K-line is for diagnostics only so is just idle at a bit below battery voltage all the time, I doubt a fault there would affect the module-module comms.

[@PineHollowAutoDiagnostics]

Hi Steve, yes the Pico would be the tool of choice for a deeper analysis. Or a CAN decoder. I learned about this stuff a bit in one of Bernie Thompson's fantastic lectures on CAN networks. He is like the mad scientist of automotive diagnostics!

Intermittent NATS faults... bad ground on the ECM?

[@jordydereus]

Yes cars can fix itself. Happend to me as well. Plugs are an hidden problem.

[@fieldsofomagh]

This case study has all the hallmarks of a bad ground. The secret to ground testing is to use a good heavy load current and making sure there are no green crusties causing an obstruction. Lower based ground connections are always prone to corrosion because of the elements. However Staten island is a law unto itself and anything is possible in that environs.

[@PineHollowAutoDiagnostics]

Grounds at ABS module carried 5A current no problem... but definitely a great thing to check!

[@lloydtucker]

K line voltage was initially 10v but jumped upto 11v, I agree k line voltage should be 1v below battery, there fore if alternator is charging correctly then Kline should be about 12.5 to 13v depending on charge rate. Did u add a jump pack at any point off camera?

[@throttlebottle5906]

and why was there never any communication on it at all.....

[@GCraigmile]

I would go straight for the aftermarket alarm system see what they tied into it can bring down the com’s,, if it’s not tied in with the COM anywhere I would go back to the ABS module connector and look at the wiring harness the only thing that changed is after you unplugged and plugged the harness back in that is where I would go and look.

[@ronaldderooij1774]

I would look deeply into the aftermarket alarm system. Also external influences can play a role. I had a car that would go into limp mode of the automatic transmission at the same spot every time I passed that spot. Eery. But no doubt there was som electromagnetic radiation at that spot. Maybe GSM transmitter, or something.

[@charlesmiller5078]

Ivan question, since you know scanners, I have a Actron scanner, when I select live data, it says its loading 115 PIDS, when I see the live data, there is only around 20 , is the scanner just not able to display the rest, or is that all that can be displayed. why would it say its downloading 115 PIDS. probably simple question. If you used your high dollar scanner, would you see 115 PIDS.

[@zoidberg444]

You know Ivan I've heard of at least 3 cases of people I've run into in the last 10 years or so having the full wiring loom on their Nissans replaced by the dealer for what sounds to me like the CAN going haywire. In one case it was a Nissan van (NV2000 i think) that this Forklift mechanic i worked with owned. Everything would loose power and go black while driving. Nissan dealers threw a shitload of parts at it and in the end it had a new wiring loom which fixed it. Who knows if it was actually the wiring or there was corrosion somewhere that replacement of the loom fixed. I would also be somewhat suspicious of that aftermarket alarm if they have spliced into one of the network lines. But that's ane even bigger handful of worms.

[@samuelbloemetjie5748]

This is one that took me 6 months to fix was the little white box under radio had nothing to do with abs or anything else was a different problem the box under radio had coins in it

[@jamesmiller3297]

Meter and a/c amplifier has coins in it. Right above radio and under small display. We at Nissan call it the piggy bank . Nissan bulletin out there. Coins will move around inside the unit and take the network out. Some times gauge problems or ac problems or no start problems. Check it out. The 04's also had that abs actuator / sensor problems . There is a bulletin on that also.

[@throttlebottle5906]

lol, sounds like typical great engineering skills.....

[@PineHollowAutoDiagnostics]

James, thanks for the tip! Could be coins, but why did the problem go away so consistently when I unplugged the ABS module?

[@jamesmiller3297]

Why did the problem not move to the other Maxima ?

[@anthonycrosier8824]

It didn’t move to other vehicle because he swapped abs module not ac amp which is the problem

[@jjacollins]

Has that Nissan got a Tape and CD player?

[@rollandsicard1628]

My EXTENSIVE systems electronic experience, tells me that you have NOT done a thorough visual inspection and test of the ABS and ECU connectors. Get out a magnifying glass and bright light, and inspect the connector thoroughly. After that, get a male pin of the appropriate size, and check each pin of the connectors for mating tension. You may well discovery something. The other variable is heat affecting the connectors. Clean each and every female pin of the affected connectors. Then apply silicon gel to all of the connector pins and make certain there is proper engagement of the connectors to the modules through thorough inspection with an inspection mirror and bright light. Then see if the symptoms repeat. There is some physical interaction of the wiring within the connectors or wiring loom. Go check it out carefully.

[@PineHollowAutoDiagnostics]

Rolland did you see where this thing was buried? I could barely get my hand down in there, let alone a magnifying glass and a bright light lol ;) But yes I agree your process would be the right thing to do in this case!

[@ticoardon8863]

In my workshop I went through a similar problem with the brakes transmission all modules it turned out that the problem was the air conditioning module because people put coins on the screen of the navigator and it Turns out that the coin slips and street just in the indidura of the module which causes short circuits in all the modules maybe in the test drive the vibration triggers the problem

My Guess is Bad Connection on any One of the CanBus Pins and plug's looking at the Corrosion under the Bonnet (Hood)...there will be an intermittent connection somewhere... Hope you find it but it may never happen again...best of luck.

[@marklenker7432]

Ok Ivan you miss the problem look at frame 12:44 on the green trace you will see a small sections between 200 250 on the lap scoop it not pulling down with the rest of them and that was before the abs was plug in. now look at frame 13:31 after the abs is plug in its the same. its not the abs module its one of the other one on the can line or a bad ground wire to the one that acting up.

[@jkbrown5496]

You are right. There appears to be about a half a volt positive bias to 3v on that one sloppy peak on both the can high and low. That could be enough to confuse the priority negotiation for the modules if whatever put that one glitch started talking a lot.

[@n3lee]

I'd probably have dumped some de-oxit in the connector before handing it back... and checked the firewall pass-through for corrosion (if it's a bulkhead connector)

[@steveo6631]

do you ever shut your headlight off? The reflection in the scanner is so irritating...

That plugging of the module and disabling all components looks like a Denial of Service Attack, not from a human hacker but from the ABS module overloading the network with message packets and letting the other modules who are waiting for a chance to communicate to standby for forever. But the module doesn't do that on the other car so who knows...

We didn't get a diagnosis on the tuna gyro.

Dirty plug or bad wire close to connection, shorting to ground, probably kicking in some sort of wiring protection. You either cleaned the connection by unplugging and replugging or moving the bad wiring away from short fooling with plug. If problem reoccurs, I would make a close visual of wiring around plug or plug itself. But what do I know

[@PineHollowAutoDiagnostics]

Definitely changed something, and that was the only thing I touched...so that is a very logical conclusion!

[@Bass654me]

I know this sounds crazy but I have a 17 rogue that gave me all kinds of crazy symptoms. A friend mechanic suggested to check the mass air flow sensor. When I say crazy my car would not move and all kinds of error codes happened until I cleaned that sensor, After that, I started the car and it was like nothing was wrong…..go figure….

[@randyhughes5160]

It could be two wires shorted or a broken wire and moving the pigtails unplug and re plug it moved the wire under the hood in a tight spot it can easily get pinched I saw this on a Jeep it was a broken mount allowing the motor to move and broke wires

Nissan TSB NTB07-043 MAXIMA; GAUGES / HVAC / WARNING LIGHTS DO NOT WORK CORRECTLY, Check this TSB It will cause the network com codes in all the modules on the high speed can. I have seen this a couple times also even cause a no start from the coins shorting out the can lines on the PCB. You have to remove the "a/c amp" and shake it, you will be surprised to hear coins rattling in the module. There is only a small slot in the module but they happen to fall in

[@PineHollowAutoDiagnostics]

That has to be the weirdest TSB that I have heard of ever lol!

[@ednewell1847]

It sure is! I did not find the TSB until after I already condemned the a/c amp for causing an intermittent no start. In hindsight the customer said they were having intermittent gauge cluster issues for weeks before the no start occurred. After watching your symptoms it came to my mind right away

[@zx8401ztv]

Dam that's an annoying fault. Perhaps the plug to the abs is a little bit dodgy on the wire crimps. I've had general electronics play up, the "I'm here............. now i'm gone", usually reappears when the owner trys to use the device lol. And worst is if it never comes back, i will never know the cause :-(

[@PineHollowAutoDiagnostics]

Actually I hope it never comes back hahaha

[@zx8401ztv]

I don't blame you :-D

[@AdrianKingsleyHughes]

Thumbs up for sample text!

[@PineHollowAutoDiagnostics]

hahaha my bad xD

Staten Island= the new Bermuda Triangle.

[@smms1276]

SWEEEET VID 🚹, 👍👍... HAD MY SHARE OF THOSE NISSANS. POOR DESIGN FROM FACTORY. ITS THE GROUND UNDER THE DASH... IVE HAD LUCK RESTORING THE COM. WITH A GROUND WIRE KIT. THE ONES FOR SOUNDS SYSTEMS. AND ALSO ADD ONE FROM DASH GROUND PASS THRU FIREWALL TO ENGINE. I KNOW IT SOUNDS LIKE OVERKILL, BUT IVE HAD DOZENS OF THOSE NISSANS, AND TRIED CLEANING FACTORY GROUNDS, CHECKING PIN FITMENT.... YADA YADA... PULL YOUR HAIR OUT KINDA DAYS. THE HAVOC THOSE FACTORY GROUNDS CAN CAUSE... BAD GROUNDS WILL BURN UP WIRING. THE A/C RELAY IS PROBABLY SHOT. ALONG WITH OTHERS... LOL, THESE THINGS ARE ALL RELATED TO GROUNDS

[@PineHollowAutoDiagnostics]

Interesting...will keep this in mind, Thanks for the tip!

[@smms1276]

MAY THE FORCE BE WITH YOU 👍

[@chadharmon5716]

This is a simple sample text Ivan lol your welcome

[@scuba422123]

hi ivan its staten island and Nissan! someone once told me when you retire you move to staten island...and buy a Nissan! let us know what happened because I don't know

[@migzauto5094]

I was working on a 2009 saturn vue with a similar issue. Ac, cluster, and a no crank no start. Happened intermittently. Hooked up break out box and found out it was the radio shorting out the network.

[@throttlebottle5906]

if aftermarket junk, very likely some fool caused it

[@migzauto5094]

throttle bottle nope. Original radio.

[@throttlebottle5906]

did it have a soda or coffee spill get into it?

[@migzauto5094]

throttle bottle nope nothing. Unplugged it and problem.went away
