Diagnostic Trouble Code Table < Occupant Classification-Ecu >
WARNING: This page is about a different variant/trim than selected.
CAUTION:
During diagnosis, a DTC code associated with another system may be stored when the ignition switch is turned on with connector(s) disconnected. After completing the repair, confirm all systems for DTC code(s). If DTC code(s) are stored, erase them all.
Inspect according to the inspection chart that is appropriate for the DTC.
