Before performing check of the starting system: Ensure that there are no DTCs in the Central electronic module (CEM), Transmission control module (TCM), Engine control module (ECM) or Brake control module (BCM) that could cause these symptoms. DTCs that affect LIN communication must be fault-traced before this check is continued.

Remedy these diagnostic trouble codes (DTCs) first.
