Look @ the module listing with AIF or Ident and see what's responding there.

Clear all of those faults, turn the ignition off, and then back on again.

You should see EKP for sure. The EKP module is located behind the rear seat corner on the passenger side.

Thank you for responding mike
The ekp is not responding I tried in both inpa and ista
I had a few MRS safety codes which I resolved
I also haD a terminal 13 CAS code, associated to can pin #7 and #8 that I wasn't able to resolve. I removed pin 7 which cleared the code.

It looks like you have can bus communication. I would check can power and ground at the EKP module.

Is the CAS, DME and key from the same car?

Make sure that you're seeing the ignition pin energize with KL15 on.

I'll double check the wire at the ekp
do you know what desire voltage should be at the CAN wires?

Yes I was told that the motor cas and key are from the same vehicle
I'm not getting any errors in ista relating to that.
The cas and dme vin#'s are the same the key I'm assuming is correct.


KL15 I'm assume is terminal 15 correct?
Is it F38 at the junction box pin 19 at cas
Or pin 2 at relief relay ?

check the power wire and the ground wire by the positive boost post on the left side of engine bay. had many of the same codes as well as no start and was cause by the ground cable in the wrong spot. never forget to recheck the simple things to like power grounds and fuses. good luck
