DTC index

:
  Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).

DTC Description Possible causes Action
B1C4323 Master Interior Light Switch
  • Signal stuck Switch held
  • Interior lamp circuit short to ground
