Possible Causes

WARNING: This page is about a different car, the 2002 Ford ZX2 and 2002 Ford Escort. However, it is still accessible from the selected car via links, so may be relevant.

Non-volatile memory configuration fault could be caused by an improper configuration file or a damaged or inoperative ECS module.

Check for hard or intermittent DTC

Ensure ignition is off. Connect New Generation Star (NGS) tester to Data Link Connector (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 B2477 was retrieved during on-demand self-test, replace ECS module. See ELECTRONIC CRASH SENSOR (ECS) MODULE under REMOVAL & INSTALLATION. Go to next step. If DTC B2477 was not retrieved, fault is intermittent. Go to next step.

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. DO NOT clear any DTCs until all DTCs have been resolved. If no continuous DTCs were retrieved, reconnect 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.
