DIAGNOSTIC TROUBLE CODE CHART
<Occupant classification-ECU>
 
 
cautionDuring diagnosis, a DTC 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(s). If DTC(s) are set, erase them all.
Inspect according to the inspection chart that is appropriate for the DTC.
