Possible Causes

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

A left side crash sensor internal fault could be caused by a damaged left side crash sensor.

  1. Check for hard or intermittent DTC

    Turn ignition switch to OFF position. Connect scan tool to Data Link Connector (DLC). See USING SCAN TOOL  under DIAGNOSTICS. Turn ignition switch to RUN position. Retrieve and record any continuous DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES (DTCS)  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B2444 was retrieved during on-demand self-test, fault is hard. Replace left side crash sensor. See SIDE CRASH SENSOR  under REMOVAL & INSTALLATION. Go to next step. If DTC B2444 was not retrieved, fault is intermittent. Replace left side crash sensor and go to next step.

  2. 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 DTCs were retrieved, reconnect air bag system. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
