Can't Find DME

So I had my car towed into the dealer due to what I thought was a dead battery.

So today I talked to the service advisor and he said they can't even find the main computer from the DME and they don't know why.

Any thoughts?

Dealer claims the checked everything obvious and still the DMA can't read what's going on.

This is a nightmare.

Well, they finally figured it out and the answer is...
It needed an entire new main computer module.
Basically it needed a new DME.

But the good news?
Somehow they covered it under some unknown to me extended warranty on the part.
I didn’t ask a lot of questions since they didn’t even charge me the 3 hours of diagnosis time.

They also replaced the battery as it was 7.5 years old. $450 out of my pocket including coding.

I only drove it home from the dealer for 10 minutes but it seemed ok so far.

ejm3 The coil drivers(MOSFETs) in the DME can go out over time or with high power coil packs. Do you have aftermarket coil packs ?





The DME is located in the engine compartment up by the fire wall... (this is a really bad video but its all I found on YT that showed the location)...



IF you have a JB3/4 piggy back... a scan tool won't be able to read the DME unless the JB has been put into map zero. Just FYI.

I’ve owned it since new and my car is exactly the way it came out of factory.
Never modded.
