DTC Troubleshooting Index: Notes

NOTE: Record all DTCs and sort them by DTC type using the following DTC troubleshooting indexes, 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 DTC B1005 and B1008 are retrieved, troubleshoot B1008 first).
Signal error DTCs

MICU
