Those are all history codes. That’s what the H denotes. They occurred in the past. If you have any codes that begin with a C, those are current codes. Do you know which module is throwing the codes, ECM/PCM, CCM, ECBM? I’ve been chasing code 41 thinking it was from the ECM but was actually from the CCM. Same code number but different problem. Code 41 from the CCM is ECM serial data circuit (loss of communications). Code 41 from the ECM is electronic spark timing circuit (open or shorted circuit). Big difference. Also is your car a vin p or vin j?
