DTC Troubleshooting Index
NOTE:
Check the PCM for DTCs and troubleshoot PCM or F-CAN loss of communication errors first (see GENERAL TROUBLESHOOTING INFORMATION
), then record all DTCs, and sort them by DTC type using the DTC troubleshooting index, then troubleshoot the DTC(s) in this order:
- Battery voltage DTCs
- Internal error DTCs
- Loss of communication DTCs (beginning with the lowest number first; for example, if B1006 and B1059 are retrieved, troubleshoot B1006 first).
- Signal error DTCs
