Possible Causes
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
A passenger-side air bag ignitor circuit shorted to battery or ignition voltage could be caused by a short to battery or ignition voltage in Light Blue/Orange wire (circuit No. 607), a short to battery or ignition voltage in Pink/Black wire (circuit No. 616), a short to battery or ignition voltage in passenger-side air bag module or RCM internal fault.
- 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 B1925 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1925 was not retrieved, fault is intermittent. Go to step 5 . - Check passenger-side air bag
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. See ON-DEMAND SELF-TEST under DIAGNOSTICS. If DTC B1925 is retrieved, go to next step. If DTC B1925 is not retrieved, replace passenger-side air bag module. See PASSENGER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION. Go to step 6 .NOTE: Do not remove or separate shorting bars from RCM harness connector. - Check passenger-side air bag circuit
Turn ignition switch to OFF position. Disconnect air bag simulator from passenger-side air bag harness connector. Access RCM and disconnect harness connector. See RESTRAINTS CONTROL MODULE (RCM) under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Measure voltage between ground and RCM harness connector terminals No. 6 (Light Blue/Orange wire) and No. 7 (Pink/Black wire). See Figure . If voltage is more than 0.2 volt in either wire, go to next step. If voltage is less than 0.2 volt in both wires, replace RCM. Go to step 6 . - Check passenger-side air bag wiring
Disconnect passenger-side air bag module connector. Inspect all crimps, terminals, fuses, wires and connectors feeding RCM harness connector terminals No. 6 (Light Blue/Orange wire) and No. 7 (Pink/Black wire). See WIRING DIAGRAMS . Also, check for pinched wires and damaged connector terminals. If any damage is found, repair/replace as necessary and go to step 6 . If no damage is found, go to step 6 . - 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 short to battery or ignition voltage in Light Blue/Orange wire and Pink/Black wire. 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. DO NOT clear any DTCs until all DTCs have been resolved. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table. If no continuous DTCs were retrieved, reconnect air bag system. Activate air bag system. See ACTIVATING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Perform system operation check. See SYSTEM OPERATION CHECK . Clear all DTCs. See CLEARING FAULT CODES under DIAGNOSTICS.
