AAAAArrrrgh, the Viper alarm "short to GRN"..I wonder if the alarm in my '03 Dakota is similar(maybe wired the same way) My Dakota was stollen, wrecked and left for dead. Still can't figure it out. I called the alarm dealer, they stated if the thief was able to start the truck, there's nothing beyond that in regard to theft detection/shut-down, or recovery tracking. Currently, "crank no start" I get fuel pressure(42psi) continuity, ground & pulse signal from CKP & CMP to Ecm no 5v out (pin#7) to ignition. Replace the ECM, everybody says, and still NOTHING!!!

🤣 run a wire anyways Paul! I support it! As always, you the man!

Hello, Paul You have mentioned partial short to ground in the video, would you be willing to explain to us what a partial short is? You have not made a video explaining a partial short to ground so far.

Someone please help me I’ve spent over 600 since Thursday still haven’t found issue. 97 Tahoe 5.7 vortec once warms up gets out of second gear can’t stay at a steady speed without it sounds like trynna stall but never ever does just have to hit gas harder to get it to stop then goes right back to doing it bs when u try to go a steady speed. Only does it when warmed up and after 2nd gear. Brand new distributor and crank but still throwing out that code. That code is the only code my truck throws but that issue I’m just so loss I need help someone please help

Great lesson to learn from!! Thanks!!

This is what I love 👏👏👏 This is what I've been looking for

He’s at again ! Teaching the next generation. Great job

Truth! Pick/choose your diag path correctly...

i am just curious i have watch many of you youtube why not go directly to the obd port to test the 5 volts reference, i watch in youtube there is a 5 volts sensor in the obd port

CLOTHES HANGER; Almost impossible to Stop. The rain run off from the outside windshield drain clogged, use a straighten clothes hanger and stick it down the drain screen slot you should be able to see the hanger go all the way to the ground take a look under the car to make sure the hanger went all the way through to the ground to clean out leaves and dirt or water will come into the car on to the floor boards and wet the fuses, two drains to clean out with a straight clothes hanger. Mercedes Benz was already sued and loss the class action for such a poor design in a $100,000 car, for water getting into the fuse boxes in and out of the car.. A free clothes hanger tool and a quick fix. How stupid is that from a certified Mercedes Benz technician Cherry Hill, N.J.

My wife found a bad wire in my car doing this exact same process.

parallel resistance is the inverse of the sum of the inverses: ie = 1/ (1/ R1 +1/ R2 + 1/R3....)

We love you too. =D

subscribed to positive lead for Tommy Volkswagen wagon was 👍 great😊

👍👍

Good job sir. I liked your lecture, very informative. Keep up the good work.

So if i know i have output voltage to Terminals 15 and 75X at 0.288 =0.29 with no signal from and for my output voltage at Terminal 50 what should i be checking from there in determining why its off and no signal is coming from it when it should ??

I have the same issue with a 2006 ML500

Scanner Danner was wondering if you had a minute to answer a question? My 02 cavalier 2.2 LS will only start when I jump pins 87/30 of the crank relay and I'm not showing voltage on top half fuses in my in car box. I was trouble shooting and one headlight has 12.5 Volts coming out of all 3 wires the other headlight has regular 0 on one then 2 others have full voltage and other wire a little less... Does half day timme running lights..... Ty so much for videos but if u had a min. I'd greatly appreciate it.. Been at it for months..Also OBD keeps disconnecting? Another clue, I don't know 🤷

❤❤❤

i put 5 volts to the signal wire it shows when i test crankshaft sensor but it doesnt show when i test other sensors on the same signal wire it only shows the 12 volt power i have 2005 nissan murano awd it dont have a icm i dont think so what is mine called can you please lead me in right direction cause i dont have alot of money for the shops im a single dad and i need to get my kids back and forth to school and this is the only car i have

When you do that bypass test, isn't it sending 12 volts instead of 5 through that signal wire? I wouldn't think the ECM would allow the injectors to fire with too much voltage running through that reference wire. I figured the ECM would see it as a short to ground or something.

V8s will usually show a stronger e4.

I installed a new cheap distributor on my 96 5.7L now I have a -23 degree timing advance for #1 cylinder. When I rotate it a tooth it points far away from the #1 cylinder pin on the cap.

Same goes for single dads - watching in 2023 Biden-economy - so just saying.

hi mr danner i have been with you for long time pls i need to sud for waring daigram pls seb me the link thank alot

Hi just want to say a massive thank you I've had a dead cls55 for 3 years now was told it was a dead ECU and spent 3 years trying to find a match finally found one but it didn't fix the issue , found your video and did what you did and had excatly the same issue and corrosion on the same fuse cleaned and car started first time !!

thank lot scanner danner pls give me link where you sub for wring daigram i will great full

Why doesn't ScannerDanner convey the reason why he doesn't use a Multimeter get the results he's looking for

Like to cancel how

Well buddy, new injectors, intake gaskets, timing adjustment, and the engine running condition degraded to the point I am certain my ECU is bad, drives fine, just don't stop, it wont idle, the ECU is a special one that is so rare it cost 3 to 4 times what every other one for the year van, its just not worth $600 more just to see if the damn thing will run right, this is why I prefer a carburetor. Radiator broke, transmission burnt up, C-6, not computer controlled, alternator burnt up, ate the brushes down to the wires, regulator corroded till the pins broke off, distributor was busted where the hold down screw was, more money has been spent on repairs than the van cost, and it is not street able still, no one wants to work on it that has the equipment to hook to it, they prefer OBDII. The fact capacitors leak out and destroy the circuit board is good reason to stick with carburetors, avoid this electronic mess.

Now when checking for a short to ground is the entire circuit supposed to be disconnected? Like checking for a open

Love from kenya ❤

Great lecture

GOOD TEACHING PLS SIR THE SIGNAL WIRE TEST DID YOU MEAN THAT EVERY SIGNAL WIRE WILL BE TEST LIKE THIS IF SO PLS FEED ME BACK THANKS

At this point i called short to grou d fault at 330 in now its 5 33 in and ther was a screen shot of fault to ground , i do this all the time lol now continue.

MAN SCANNER DANNER YOU ARE BAD A$$!!! I have learned soooo much just watching your videos. I can't go to school at this moment, however these kids have sooooo much of an advantage to learn and do something with their lives, but don't take advantage of the situation... I wish when I was growing up we would of had KZbin or OTHER RESOURCES to learn.......

Flippin so helpful thank you

no time is late am getting the knowledge now in 2023. thanks

wire,ign too batt negative or frame.,for test shorted too ground

In my Mercedes-Benz e320 1995. What does fuse #5 control

Douche the fusebox terminals with Deoxit 5, lol. It will work!

This video is super helpful. Thanks a lot. Please where can I download that wiring diagram?

corrosion because of the top AC vent/condensation maybe? MAN I love the diagnostics you do on your channel!

Just love the instructional explanation this man Scanner Dan provides. He intensely goes thoroughly through many of his explained. Keep Truckin'😂😂😮😅😊😊

I had to subscribe so much knowledge. Had another KZbin mechanic tell me he never seen computers do that . Thanks wish I knew which year and manufacturers do this 😁👍🏻👍🏻👍🏻

THANK YOU SO MUCH FOR THIS VIDEO! I'm having the exact same problem with my 2013 C 250! The engine misfired due to failed spark plugs and a broken head gasket. I went ahead and fixed that, but there is a separate issue with my car not starting and not connecting to the ECU. My cooling fan also blows at full speed with the car off. If I open the doors, the hood, or the trunk, it triggers the fan even if the ignition isn't going. I have to unplug the main relay for it to stop. A friend of mine who works on European cars said he couldn't find a short, and that it's probably my ECM that's fried, but he didn't do the 5v reference. He just tried to get into the ECU with the OBD reader and failed. He could communicate with all the other modules, but not the engine or transmission. From watching this video, I'm starting to think that I also have a short somewhere. It was termite season here in the south, so I wouldn't be surprised if they got into my engine and chewed some wires. Also, lizards seem to enjoy my car, so I wouldn't be surprised if one of them got to the wiring somehow.

Hey Dan Same exact issue i'm having. I have power to ecu still no crank. Changed starter also. 2004 clk 500 mb.

I have a couple of high school students, I tell them all the time, no u tube editing shows the real case study results. Even seasoned technicians have situations that result in difficult questions. The training and learning curve never ends. Great training video.

Question!! So I am doing the test Lea to ground and the other test lead to the wire. With the ecm and the in this case throttle body disconnected, and I get O.L. Reading. What does O.L mean in this case?
