DTC Troubleshooting Index
NOTE:
Check the ECM/PCM for DTCs and troubleshoot ECM/PCM (see
GENERAL TROUBLESHOOTING INFORMATION
) or F-CAN loss of communication errors first, 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 B1008 and B1011 are retrieved, troubleshoot B1008 first).
- Signal error DTCs
