STRANDED by the ASD Circuit! Here is HOW we Tested and Fixed it! Easy!

Our automatic shutdown (ASD) Circuit took a major plunge on us and it completely left the jeep Immobile! IF we were camping or somewhere remote, this would have been a terrible scenario but fortunately we were home! We literally drove the jeep into the garage, turned it off, and when we went to start it 1 week later, it would not start. It would only crank forever and not start. You know how much we love the crank and no start condition. If you haven't seen our video on replacing the PCM from Ares, feel free to check it out here • Our Jeep Computer DIED...

Hi Bro , I got the codes 42 and 54 on my yj 1994, what does these codes stand for, I also have an issue when the car rpm is low it's start to choke like it's goning to shut off but when the rpm is high it's okay , this issue happens when the car is cold once it's hot the issue becomes a little bit better

[@hasanfaridoon5891]

I forgot to mention that , I already cleaned the fuel injectors, cleaned the throttle body, I also sprayed wd40 on the manifold but it was fine , I also changed the fuel filter, but still can't figure out what is the problem with it

[@michaelpearson6253]

Awesome video garage couple I'm so glad I stumbled across this video because I feel that this might correct my problem with my caliber I was having trouble starting it after doing some repair I got inpatient and stupidly decide to jump the main relay when I should have did a throttle relearn. I changed the throttle body before this repair and had the red light in bolt when I jumped the relay.But I did get it started after a few difficult tries but after the first day have had no luck I do not show any voltage in tipm fuse spots 22,23,24,26 which powers up cam shaft, crank shaft sensors, fuel pump, ignition and two relays your talking about in your video. what do you suggest I do to correct my mistake of jumping main relay I am not confident with electrical but can follow directions please any advise would be much appreciated

Hands down best explanation and troubleshooting video. You may become my jeep guy. Lol we will see in the morning

[@IAmRootGarage]

You guys are super fun. I found you because I had a similar issue. but I started with the fuel on my 98 TJ. I checked the pressure and it was not priming, I could prime it then at some point it would lose the prime again, So I replaced the pump. After replacing the pump it would start well it started but it sputtered and backfired. Then all of a sudden I lost all of the gauges on the dash. so I was pretty bummed and at that point I lost the aldl and was sunk. Then I let it sit for a couple of days and went out with a test light and rechecked all of the fuses again. None were bad and it still wouldn't start. I then decided I was going to do a pinout on the computer like you guys, and I didn't find any issues so I was scratching my head, and out the plugs back on the computer. I then noticed that the gauges started working again and I had access to my ALDL, so I turned it over and it started right up. SO now it runs, but anything over 70 miles an hour it sputters and spits. So I need to do what you did and follow the wires and make sure I don't have any issues like you, but that is tedious and takes a while. For now it drives around town without issues. Thanks for this video it was really helpful.

Excellent diagnosis on the ASD. I have a JK and my ASD has tripped the fuse a couple of times.

This was only the latest symptom, my first problem was the jeep would retain ignition power or some ignition power after I turned the key off, resulted in my Jeep staying running even with the key taken out. Then it started dying while driving and one day it wouldn’t start back up, I noticed the ASD relay was hot so I replaced it with the horn relay and it started right up and now issues seem to have all gone away, not convinced it’s fixed but this may be a problem I have As well.

Great video. I think I'm closer now to solving my intermittent stall. When the jeep warms up it stalls and it won't start until, with the key in "run" I hear the fuel pump kick on.

Very interesting ASD discussion. My problem is quite a bit different -- but similar, go figure! Very infrequently, like months apart, I will be driving along without any problem and my 2007 Grand Cherokee just stalls -- no engine light, all electrical power okay. So I pull over, put vehicle in park, restart without any problem and away I go. Maybe weeks, or months later -- boom!!, same thing happens again. Park, start and away I go again. Obviously we are not taking it out on the highway, only back roads -- can you imagine the danger of driving at 60mph and having this happen? Anyway, swapped the ASD with the relay for the HVAC (same relay) yesterday and will see if the problem reoccurs -- but it sure would be nice to know if it is "really fixed". Oh, by the way, the error code is the same P0688 you mentioned in your ASD video.

[@Garagecouple]

Hello and thanks for the comment! Sorry to hear about your issues. That sounds like a parking or neutral switch in the transmission. In any case I'd change out all of the electric switches like the crank and cam position sensors, transmission sensors, etc. Cheap and quick and hopefully fixes your issue

wonder if your jeep has that 10 amp fuse for the ASD in the holder on the driver's side of the dash ie my Ram 1500?

[@BoldSooner058]

I had a problem with the wire going back to my fuel pump. It had fallen down on the drive shaft and was worn through. Every time i stopped at a light or sign it would blow the asd fuse. After changing out many parts I finally found the issue and fixed it. Then a month ago the jeep didn't want to start. It seemed like I had no fuel pressure at the injector rail. I changed out the fuel pump and it started up perfect and ran great for a day. Then it started stalling and not wanting to start. The wierd thing was i was not getting any check engine light. I bought a code reader that does live data and hooked it up. I have me the code for the ASD CIRCUIT SHORT. I started messing with the wires that go to the pcm and the jeep started but then when I would mess with the bundle of wires it would start to die. I could let go and it would smooth out and run fine. So I figured I had a short in that bundle. I started where that bundle mounts to the fire wall and checked continuity all the way over to where they attach to the pcm. All of the wires had continuity. I'm at a loss now as to where to go.

[@bigbang7897]

Hi i'm watching your video from Ireland and have a question my 1998 ZJ 4L developed a misfire and would occasionally buck with a lack of power today when I started it the engine ran for about 30 seconds and then stopped I cranked it over but no start then after a few attempts it started. I listened to your comment about the crank position sensor do you think it might be the issue I did replace the distributor so I don't think it's the cam sensor but i'm open to any help.

There's wiring and then there's jeep wiring, IDK. Did you run across anything like that.

[@jdubya54]

nothing better than stepping through a successful diagnosis. i’m fighting with a 2007 jeep commander myself. i cant get ground on the relays. i might try jumping the asd if i run a separate ground wire from the relay i can get it to crank but it won’t start. might be a bad pcm. trying to figure a good way to diagnose that

Awesome content. This crank no start issue I’m having is pointing me to the asd for my issue on my ram 1500. I traced it to the asd relay. I have 12 bolts at both points and I have a bad grounding. I did the jump method and the truck turned over but ran like garbage and would shut down right after letting off the gas. I have changed the crankshaft sensor already and found frayed wires at the sensor. No idea where to go next!!!

[@chuckbelcher179]

Make sure you have good signal from the cranksensor , fix the frayed wires ' fix the ground . check the throttle body and idle air control valve for carbon buildup and clean with throttle body cleaner if needed , check internet for how too also check air filter and replace if needed .point is when you have the gas peddle depressed you allow more air into the throttle body and when you let off the gas you restrict airflow , this is where a clean iac value and clean throttle body come into play. Hope this helps.

[@timhise5942]

I’ve got a JKU and having a similar issue. My 25amp ASD fuse blows after driving the vehicle every few miles. Not entirely sure, but seems like the engine can idle a long while but under load the issue occurs. Any idea why this would happen? Is it a short somewhere? I do wish my setup was as simple to follow as yours but the newer jeeps are more complicated for sure.

[@peterpowers4851]

So here a sort of complicated question about the ASD system. I own a 2016 jeep wrangler (4 door if it makes a difference) and I hardwired a dash cam onto it using a fuse tap. Because of the location of the fuse, and because a couple other fuses already have fuse taps on them, I chose to use the fuse (not relay) for the ASD since it gives me switched power and has a larger fuse. It works great but as I have had this set up for about a month now I have noticed that occasionally the dash cam is off while I'm driving and will not power on indicating it is not getting power. Does the ASD system sometimes turn off when you are driving? This scenario rarely happens but when it does, it only stays off for a few minutes and then turns back on. Trying to figure out if it's the dashcam that is at fault, or if the ASD system sometimes will shut off during driving for a few minutes. I have only noticed this twice in the last month so it is very rare and I can never do anything to recreate it, seems very random.

3:16 The center terminal of the relay is 87a. That's the normally closed position. Apparently, Garage Couple is referring to jumping between 30 and 87, far right and center-left in this video. That would simulate the relay closing and cause the starter to crank.

[@Garagecouple]

Yup, bypassing the relay..

[@The4thshodow]

Thank you so much for breaking this down. Did not mention the relay numbers in the video and mine is different

[@johngreen6643]

Also when I'm changing an in tank fuel pump and need to drain the tank of fuel I disconnect the fuel line & run it to a gas can then jumper the same pins on the fuel pump relay. Much easier than jamming a hose down the fill tube & siphoning the gas and no nasty taste of gas when trying to prime the siphon hose.

[@Nehmo]

@@johngreen6643 Every time I've dropped a fuel tank it's because I needed access to the broken fuel pump inside the tank. But that's a good tip for occasions when the pump is still good.

Hello and thank you for the information. I was about to buy a new crankshaft sensor but decided to try your ASD bypass. It started right up. Now my question is how do you know for sure, by doing this bypass, that it isn't the crank or cam sensors causing it not to start? Could it still be a bad crank or can sensor? Thanks!

[@johnmartensen4278]

Bypass probably means just bad pcm communication wire. If it was a sensor it would have a code for that.

[@michaelcorey7962]

Hi, I have a 98 Wrangler with exact same problem. it will crank and crank but no start. What would you recommend as first diagnostic step(s)? I replaced the distributor and am pretty sure I did it right. there is fuel in the fuel rail...I will replace spark plugs tonight but I feel hopelessly lost and cant afford a mechanic bill right now. Any help would be greatly appreciated.

[@roninpawn]

Similar issue on my 1997 Dodge B1500 conversion van. (basically a 3.9L Ram Truck under the hood) And today I said to my father, "We should just shove a penny in the ASD." Now that I see your DID bridge the relay to test, I'll probably actually try it. But, my question is... When the ASD closes correctly, do you get one click; or two? Because when we turn the key to pre-crank position, I hear and feel the ASD click once; then 1 second or less later; I hear/feel it click again. So the PCM is successfully sending a ground. But that 2nd click could be the PCM disengaging the ground. We've already replaced the crank & cam sensors, coil, distributor cap, rotor, plugs AND plug wires. (A lot of it was cheap, and sending it to a garage would probably get into 4-digits quick, so why not just buy and change EVERYTHING it could be?) Today I confirmed the wire-continuity between the coil and the computer and between the coil and the ASD relay by stripping them just before their mountings. Anyway, if the relay is closing, and then opening again -- which is what it sounds like... Either the computer is sensing a real, genuine misalignment and refusing to start the engine to protect it, or the PCM is just... wrong and bad. That's my guess, anyway. Anything you can add is greatly appreciated.

Good luck!

I’m having the same problem on my 1997 jeep wrangler 2.5l and I switched out the the coil and wire and spark plug and fuel pump. It still would crank over but not start so I checked the spark again and didn’t get any spark so I jumped the relay and got spark but it’s still not wanting to start up?

2006 jeep commander 5.7L why do you think that sometimes the ASD relay clicks rapidly and no vehicle start

[@NicholasBowles]

I hope you can reply , I have a 95 Jeep Cherokee with a crank no start issue. I reverse polarity, jumped it with jumper cables, and now my jeep won’t start. I have no fuel and no spark have replaced all the relays, Ignition coil, cap, and still no start. Any idea what could be the issue?

[@ethanedwards6179]

I was wondering if I could get some help I’m have trouble with the asd fuse it keeps blowing at random points completely shutting down the car I replaced it and it starts right up, I’ve replaced the relay and no change.

[@zacharysommerfeld3239]

I get codes for bad relay circuits for my fuel pump, hi and lo radiator fans, and my asd, would this all be caused from a bad asd circuit or are they all bad and i have a bigger problem?

I’m having problems with a 2001 jeep wrangler. I’m working on this vehicle with a group of people in my automotive class. The ASD relay does not click, and the pcm is getting the power and ground that’s needed in the connectors. I also have no communication to the vehicle. I check my 5v reference circuit and was only getting .40 volts with key on. I started unplugging sensors except the crank, cam, and battery temp sensor because I ran out of time that day. But my main question is do the ASD relay have to be active to receive 5 volt supply?

[@kellybest3472]

My Jeep rear axle broke and shut me down immediately. I am almost positive that the ASD shut everything down for safety purposes my question is now, how do I reset this or get it right again? I am learning step by step on here and it does boggle the mind sometimes. Great video.

[@Garagecouple]

Hope its fixed by now. You will have to test each component one by one. GLad you are safe

[@Vcoldduck]

Nice tweezers

Hello I have a question for you and I hope you can tell me how to fix it . 1993 jeep yj 4.0 auto shutdown problem

[@vortex1339]

My parents has 2013 ram 1500 and sent it to local mechanic shop and found the issue. So, they by passed that asd and told my parents if it stops working, it will not run again.And it did. It won’t start anymore. So, do I just check the the wire that is going to pcm to see if it’s burnt or disconnected?

Hi Garage Couple, Jeep WK Hemi 5.7 Limited Driven 150,000 miles Usually Starts and stalls after 2-3 seconds Sometimes starts and runs fine Active codes are: Open circuit code Saved Codes: U0100 & U140E Note: When car starts fine; turning the steering wheel right will cause a sporadic amount of lights to show up on dashboard! No blown fuses that I can find! Do you think it is a problem with the ASD and should I take the same steps as you did? My mechanic is telling me to order a new PCM :/

[@RusellProctor-fd4tw]

I just found this video. I'm having problems with the asd. My jeep xj was running perfectly one minute and wouldn't start the next.

[@adamgregory6777]

Have a 95 xj starts and runs fine. Drive it 10 to 15 miles shut it off .when start to drive again it acts like it wants to stall no gas peddle response. Shut down 20 to 30 minutes later runs fine.

[@axeldeleon6281]

So my yj won't start right off the back. It cranks but I have to give it like 10 min for something to click and then all the relays click and it starts... any ideas?

[@chadtucker2875]

When I turn the ignition on the ASD and fuel pump relay starts chattering. When I try to start it. It just clicks and nothing. The chattering doesn't start again until I switch the ignition to off and then back on. Any idea witch sensor is acting up?

[@eyielding]

Do you have any videos on the upstream o2? I need help re-wiring the connector. I have a97 tj

[@Garagecouple]

We do not, but you can download the wiring diagram for your year and it should make it pretty easy, total of 4 wires i believe

[@alexbocanegra7168]

My car keeps dying while I'm driving or at a stop... Not sure what it is the battery is good and the alternator are good. It does even if I'm trying to pump the gas it just shuts down. I do have an aftermarket radio that was recently installed a few months ago don't know if that could be part of the problem..
