Durametric code results: need help!
 

Looking for a little help from the Porsche experts in this forum.

I had 2 dash lights on my 2003S lite up a couple of weeks ago: ABS & PSM OFF. I checked for codes with a Durametric short test and got:

P1600. (Fault code 216). CAN timeout PSM
P1601 (fault code 660) CAN timeout - instrument cluster
P0571 (fault code 364) Brake pedal position sensor

What should I check? I checked brake pedal for switch operation and brake lights work fine. I had recently added DEPO LED brake lights; could that cause a problem?

Not even sure where to start with the CAN problem. Otherwise the car runs fine.

Is there a service book available with fault codes and follow up diagnostic procedures?

CAN might be the abbreviation for CAN bus electrical system. And after installing the depot lights, it may have changed/altered communication. Try installing your old pair and clearing the codes to see if the problem goes away.

thanks,
I'll give that a try.
