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.
A right seat belt pretensioner circuit short to ground fault can be caused by short to ground in Yellow/Red wire, short to ground in Yellow/Black wire, short to ground in right seat belt pretensioner or faulty RCM.
- 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 . - 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 . - 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 terminals No. 15 (Yellow/Red wire, circuit No. 1081) and 16 (Yellow/Black wire, circuit No. 1082) separately. See Figure . If resistance is less than 10 k/ohms in either circuit, repair short to ground in appropriate circuit. See WIRING DIAGRAMS . Go to step 5 . If resistance is more than 10 k/ohms in both circuits, replace RCM. Go to step 5 . - Check for intermittent fault
Refer to continuous DTCs recorded in step 1 . If DTC retrieved in step 1 was an intermittent fault, check for cause of intermittent faults in Yellow/Red wire (circuit No. 1081) and/or Yellow/Black wire (circuit No. 1082). 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. 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.
