52B-DIAGNOSTIC TROUBLE CODE CHART<SRS-ECU>

CHECK CHART FOR DIAGNOSTIC TROUBLE CODES

caution

During diagnosis, a diagnostic trouble 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 diagnostic trouble code(s). If diagnostic trouble code(s) are stored, erase them all.

Inspect according to the inspection chart that is appropriate for the DTC.
