1991 600SEL
1991 600SEL ASR Light
1991 600SEL - ASR light ON and LHM as well.
Faults:
ASR - Fault 32 - CAN: No communication to DI module
EFP/TPM/ISC - Fault 117 - CAN: No reception from EZ N1/3
I checked CAN resistance between the 2 pins on both ignition modules as well as CAN wiring check from ASR module to each ignition module and everything is good.
Is this car equipped with only the left and right ignition modules or is there a 3rd one communicating with the ASR? I couldn't find any wiring diagrams for 1991 but looking at 1992 diagram I found N1/4 being the left one and N1/5 the right side. Any idea what N1/3 is?
Thanks.
