NOTE: Before troubleshooting any of these DTCs, check the battery/system voltage. If the voltage is low, repair the charging system or replace the battery before troubleshooting the SRS. If the battery/system voltage is now OK, ask the customer if the battery ever went dead. A dead battery may trigger one of these DTCs.

1. Erase the DTC memory.

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.

Does the SRS indicator stay on, and is DTC 52-Bx, 52-Cx, or 52-Dx indicated?

YES - Replace the SRS unit.n

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, go to the DTC Troubleshooting Index.
