Possible Causes

Crash data memory full is caused by a crash event which deployed the air bags.

  1. Check for hard or intermittent DTC

    Ensure ignition is off. Connect NGS tester to DLC. See USING NGS TESTER  under DIAGNOSTICS. Turn ignition switch to RUN position. Retrieve and record any continuous DTCs. See RETRIEVING FAULT CODES  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1231 was retrieved during on-demand self-test, fault is hard. Replace driver-side and/or passenger-side air bag modules (if deployed) and go to next step. See REMOVAL & INSTALLATION  . If DTC B1231 was not retrieved, fault is intermittent. Go to step  2 .

  2. Check condition of RCM mounting bracket

    Inspect RCM mounting bracket for damage. See RESTRAINTS CONTROL MODULE  under REMOVAL & INSTALLATION. If RCM mounting bracket is damaged, replace RCM and mounting bracket. Restore sheet metal to its original shape and structural integrity and go to next step. If RCM mounting bracket is not damaged, replace RCM and go to next step.

  3. Check for additional DTCs

    Refer to continuous DTCs recorded in step  1 . If any continuous DTCs were retrieved, go to diagnostic trouble code identification table for direction to appropriate test. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION  table. If no continuous DTCs were retrieved, restore air bag system. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
