DIAGNOSTIC TROUBLE CODE TABLE < Occupant classification-ECU >
CAUTION:
During diagnosis, a DTC code associated with another system may be set 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 set, erase them all.
Inspect according to the inspection chart that is appropriate for the DTC.
