Thank you so much. Is this diagram valid for PKDM CIVIC 2007? Chassis code is NFBFD1 Engine code is R18A1
Also, I'll share the history of problem. The code generated due to negligence of electrician who bypassed the compressor relay during AC work. ECU got short. That's for dead ECU I guess. I got the ECU repaired, now the following 2 codes are showing:
P1659 (ETCS RELAY OFF MALFUNCTION)
Error is Current and Temporary
P0603 (PCM/PCM INTERNAL CIRCUIT MALFUNCTION, KEEP ALIVE MEMORY KAM ERROR)
Error is Current and Temporary
Since an electrical short happened, should I check all the ground connections, fuses, relays, wiring, sparking, wire melts etc? Anything you would like to recommend? How should I go about the whole thing? What should be the order of job in priority?
The car is a bomb at the moment I guess. I'm not taking it out of workshop before all necessary safety checks.
