Possible Causes

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

A right seat belt pretensioner circuit short to ground fault can be caused by short to ground in Yellow/Red wire (circuit No. 1081), short to ground in Yellow/Black wire (circuit No. 1082), short to ground in right seat belt pretensioner or faulty RCM.

  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 B1883 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1883 was not retrieved, fault is intermittent. Go to step  4.

  2. Check right pretensioner

    Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Turn ignition switch to RUN position. Perform on-demand self-test. If DTC B1883 was retrieved during on-demand self-test, go to next step. If DTC B1883 was not retrieved, replace right seat belt pretensioner. See SEAT BELT PRETENSIONERS  under REMOVAL & INSTALLATION. Go to step  5.

  3. Check right pretensioner circuits

    Turn ignition switch to OFF position. Access RCM and disconnect harness connector. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Remove right pretensioner simulator from harness connector. Measure resistance between ground and harness side of RCM connector terminal No. 15 (Yellow/Red wire). See Figure. Measure resistance between ground and harness side of RCM connector terminal No. 16 (Yellow/Black wire). If resistance is less than 10 k/ohms in either circuit, repair short to ground in appropriate wire. See WIRING DIAGRAMS . Go to step  5. If resistance is more than 10 k/ohms in both circuits, replace RCM. Go to step  5.

  4. Check for intermittent fault

    Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Perform on-demand self-test. If DTC B1883 was retrieved during on-demand self-test, check for cause of intermittent faults at or near right seat belt pretensioner harness connector. Repair any intermittent faults found. If intermittent faults are found and corrected, go to next step. If intermittent faults are not found, go to step  2. If DTC B1883 was not retrieved during on-demand self-test, fault is intermittent. Check for cause of intermittent short to ground in Yellow/Red and/or Yellow/Black wire(s). 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.

  5. 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.
