Appendix C: Diagnostic Trouble Code Definitions

This appendix lists the various different Diagnostic Trouble Codes (DTCs / error codes) that the BMS can set as well as their common causes.

NOTE: The DTC IDs shown below in parenthesis assume that the DTC ID table has not been changed from the default values (under "CANBUS Settings" at the bottom).
