Understanding diagnostic codes
I did a diagnostic scan and came up with these codes
Module 1 - H41
Module 4 - H67
The H67 is nothing but an A/C problem but i am confusied with the H41 code. Is it a CCM DTC or does it fall into the same catigory as the code H67 meaning its is teh ignition modual?

DTC 41 is PCM serial data circuit loss of communications. The PCM is not responding to the CCM request for input. Could be a bad connection. Check the wiring & clear code to see if it comes back.
