What is a eatx shutdown relay

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.

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.

EATX SHUTDOWN RELAY AND THE ENGINE CONTROL FUSE

However, I don't know where this relay is located, and no manual or diagram that I can find lists it. I suspect that it is probably listed somewhere by some other name that I don't recognize.

Now, of course, comes the actual question. Thank you for your help. Do you. The closest I have is a '94 service manual, but it should be the same.

VEHICLE RELAYS - Testing from the relay base

Hello: I am new to this discussion forum as well. I do not know how to post my own question. Please advice me how to do this as well as answer my question, please. I brought a dodge grand caravan used. The guy that I brought the vechicle from told me about this engine light that is on and that it comes on every certain number of miles, exactly what does this means?

October It re starts and idles a little rough but no more stalling I've replaced the plugs and filters. Any ideas as to what is going on with my van would be greatly appreciated.

Have you read your owners manual about the check engine light? Does your check engine light come on for a period of maybe one day or when your done filling up with gas? If your check engine light comes on it can mean that the computor sense's you have gotten bad gas or you have left the engine running while filling up your gas tank. This confuses the computor and takes it a while to reset itself into thinking the gas is not bad and its ok.

Mine being a states this in the owners manual about the bad gas and leaving the gas cap off while the engine is running. This can cause a rough engine and also it can cause stalling. I would contact your service manager at your local dealership and ask him or even the assitant manager what he thinks. I do know that Chysler is telling people with this problem to change sparks plugs to a different type but I can not remember which ones whether copper or not.

My dealer installed new plugs-one new spark spug wire and reflashed the computor and its fine now. The reflashing of the computor resets it to the original setting.

Contact your service manager they normally are nice people and will help you figure things out along with telling you if this is a past or present issue with your vechical.

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?
