Possible Causes

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

An incorrect module design level code could be caused by an RCM installed on wrong vehicle, an incorrectly programmed RCM or vehicle ID terminals not connected as expected.

  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 FAULT CODES  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC C1414 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC C1414 was not retrieved, fault is intermittent. Go to step  3 .

  2. Check vehicle identification PIDs

    Using scan tool, select PID/DATA MONITOR AND RECORD. Select PID VEHID. If PID is correct for vehicle configuration, replace RCM. Go to step  4 . See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. If PID is not correct for vehicle configuration, repair appropriate circuit or no connect condition. Go to step  3 .

  3. Check for intermittent fault

    Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Refer to continuous DTCs recorded in step  1 . If DTC retrieved in step  1 was an intermittent fault or if directed to this step from step  2 , check for cause of intermittent open in Black/Light Blue wire (circuit No. 875), Violet/Orange wire (circuit No. 298) and Blue/Light Blue wire (circuit No. 650). See WIRING DIAGRAMS  . Attempt to recreate fault by flexing wire harness and cycling ignition switch frequently. Repair any intermittent problems found. Go to next step. If DTC retrieved in step  1 was not an intermittent fault or if not directed to this step from step  2 , go to next step.

  4. 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, reactivate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
