ASD relay clicking. Thread starter English Guy 1 Start date Apr 17, English Guy 1 New Member. Good morning from England one and all,just joined this Jeep TJ Wrangler forum so my first post on the site.

Have filled in the info on my 4. Recently over the last month i have been experiencing a intermittent problem with engine stumbling during driving. When this occurs i have stopped the jeep and looked for the source of the problem. So my first though was bad relay,so immediately swapped the ASD for the horn relay as same part number item. The result was no change same problem occurred.

So consulted the TJ Jeep service manual fuel system diagnosis and testing fig 24 ASD and fuel pump relay terminals. Followed the procedure on all three of my relays ASD fuel pump and horn. All passed the test with Continuity pass and non continuity etc all pass testing as per specification. I have found a fault here also,sometimes when i turn ignition key to on position i hear the in tank 19 gallon fuel pump run constantly this is wrong.

As stated by the service manual this should not happen. It is designed to run approx 3 seconds then the PCM shuts it down via the ASD relay by opening the earth connection due to the java download csv file from url not running as no crank signal to PCM. Most of the time i do get fuel pump running just for the three second prime function in the ignition key on position.

Cleaned them all up to good clean contact surface finish and reattached securely. Can some kind sole with similar experience point me to a possible cause of this problem.The electronic engine management systems on modern vehicles are made up of sophisticated fuel and ignition systems that work together for the vehicle to run.

Both systems are made up of various components that all work together to provide timed fuel and ignition for the engine. One of these components is the automatic shutdown relay, commonly referred to as the ASD relay. As with most electrical components, the ASD relay is subject to the normal wear and tear associated with normal service life, and when it fails, it can cause problems for the entire vehicle.

Usually, when the ASD relay has failed or is having a problem the vehicle will produce a few symptoms that can alert the driver that a problem has occurred that should be serviced.

One of the most common symptoms of a bad ASD relay is an engine that will start, but stall out almost immediately, or at random times. If the ASD is having any problems that interfere with its ability to supply power to the injectors, coils, or whatever other circuits it may feed, then those components may not function properly and problems may arise.

A car with a failing or faulty ASD relay may stall immediately after starting, or randomly while operating. Another symptom of bad ASD relay is an engine that will not crank at all. As many of the engine management systems are wired together, if any of the circuits that the ASD relay provides power for go out as a result of a bad ASD relay, then it may affect other circuits, one of them being the starting circuit. A bad ASD relay can indirectly, and sometimes directly, cause a starting circuit to not have power, which will result in a no crank condition when you turn the key.

If the computer detects that a problem with the ASD relay or circuit has occurred, it will illuminate the Check Engine Light to alert the driver of a problem. The Check Engine Light can also be activated for a wide variety of other reasons, so it is important to have the vehicle scanned for trouble codes to determine what the exact cause of the problem may be.

For this reason, if you suspect that the ASD relay has failed, or is having a problem, have the vehicle serviced by a professional technician, such as one from YourMechanic to determine if the car needs an automatic shutdown relay replacementor if another issue needs to be addressed.

No fuel pressure Lack of fuel pressure can be caused by a failing fuel pump or a clogged fuel filter.Two weeks ago I pulled it into the garage and turned it off. I heard a noise coming from my dash, sounded as if my CD player were trying to eject a cd. Powered back up and pressed eject, nothing to eject. I pulled the cover off the box and determined the clicking sound was coming from an ASD relay. Went and purchased a new one.

Removed the ASD relay and began my internet search. Two days later I try to start it and it was completely dead. Took the battery to an auto store who tested it; tested fine but low charge - charged it.

Rule out battery. It appears I am not the only sad sack who has experienced this problem. Fist of all, the ASD is clicking without a key even in the ignition, let alone turned to be powered up. I tell him the battery tests fine and share with him that I have seen a lot of on-line posts where people are suggesting to replace the PCM but they continue to have the same problems after replacment.

The mechanic at the dealership told me it was likely not the PCM since the ASD relay is actually getting powered or something along those lines. So today I go out with a freshly charged battery and try to get it started so I can take it to the dealership. But it did click a lot louder. Towed to dealership. I ask if he is sure that is the problem. He proceeds to tell me that they will not know if there are other problems until they fix the PCM and run the codes to see what else pops up bad.

Is this unacceptable to anyone else but me? But I am at a severe disadvantage. Replacing a fuse is about as much as I can do in the automotive field and I am completely out of my league. It just seems sloppy and lazy to me. I tried to have a conversation with this young kid this morning and I may as well have been speaking Swahili.

Maybe the PCM is the problem? But a majority of the posts I read are where people replace their PCMs and they continue to have the problem. After all, what am I going to do, fix it myself? This is not just a cathartic release… do any of you have advice as to what YOU would do minus me going to automotive school if you were me?

The power supplied to the fuel pump, ignition coil, fuel injectorsand parts of the power module is controlled by the logic module through the Automatic Shutdown Relay ASD ; the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.

The relay is located in different places on different years. In the — model years, the power module houses the ASD.

From about on, the ASD relay was in a plastic underhood relay box at the left fender well. The ASD relay is closed allowing power to flow through it when the ignition is first turned on.

If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module.

This causes the engine to shut down. The logic module monitors the relay driver. If it senses that the relay driver is not responding correctly it will trigger a code. If the logic module does not sense an absence of current when the circuit is open, or 12 volts DC when the circuit is closed, it knows that the circuit is open or shorted, and triggers code If it does not see 12 volts DC when the relay is activated, it triggers code Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

That will back feed 12V to the fuel pump through the ASD circuit. If the pump runs [it should be easy to hear], the ASD relay is bad. If not, the fuel pump or its wiring is probably the problem. We strive for accuracy but we are not necessarily experts or authorities on the subject.

If doing it that way does not disable the alarm system you may have to the anti-theft system reprogrammed.

The time in between the engine replacement could have been enough time for the anti-theft system to forget its programming to the key. However here is a little more information on disabling the alarm system from Jeep:. Vehicle Theft Security System Passive disarming of the VTSS occurs when the vehicle is unlocked using the key to unlock either front door or the liftgate. Once the alarm has been activated horn sounding, lights flashing, and the engine no-run featureeither disarming method will also deactivate the alarm.

Depressing the Panic button on the RKE transmitter will also disarm the VTSS, but the horn will sound and the lights will flash for about three minutes as part of the Panic feature. Refer to Power Lock Systems for more information on the Panic feature. Vehicle Immobilizer System: Active disarming of the vehicle immobilizer system occurs when the Unlock button of either of the two Remote Keyless Entry RKE transmitters is depressed, regardless of ignition switch position.

This is the only way that the vehicle immobilizer system can be disarmed. Following successful disarming of the vehicle immobilizer system, the set lamp on top of the instrument panel will stop flashing. Q: Asd relay clicking it wont start asked by Shawn.

Power washed car on Tues. Drove it in gargage. Figured it was just doing this since there was no juice to power much of anything. Tried to charge on home charger. No dice. Battery wouldnt take. Figured I needed more than a 50 amp chargr. Had friend help me roll car out of gargage to jump start off his car.

Rolled car back in, jacked car up removed wheels and battery. My Optima turned out bad as tested Autozone. I thought I found my problem Returned with new battery, hooked up and put key in ON position.

Also Clutch Position relay clicking. Put ASD back in. Didnt want to deviate from original problem. All looked OK. Cleaned up some powersteering fluid that overflowed.

Found cap off from previous spirited driving session! Put all fuses back in and tried to start car, even though the clicking was still happening in ASD relay. Got car to start. Turned car off. Put key in ON position. For a couple seconds NO Relays Clicked, then I heard the ASD trying to click, and then the click would sound like it was shorting out, if that makes sense. This is driving me nuts.

Anyone know where to look?
