Possible Causes

A passenger-side air bag ignitor circuit shorted to battery or ignition voltage could be caused by short to battery or ignition voltage in Light Blue/Orange wire, short to battery or ignition voltage in Pink/Black wire, short to battery or ignition voltage in passenger-side air bag module 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 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 .
2. Check passenger-side air bag module
   
   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.
3. Check passenger-side air bag circuit
   
   Turn ignition switch to OFF position. Disconnect passenger-side air bag simulator from 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 harness side of RCM connector terminals No. 6 (Light Blue/Orange wire, circuit No. 607) and No. 7 (Pink/Black wire, circuit No. 298) separately. See Figure . If voltage is less than 0.2 volt on either wire, replace RCM. Go to step  6 . If voltage is more than 0.2 volt on both wires, go to next step.
4. Check passenger-side air bag wiring
   
   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, circuit No. 616). 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 .
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 short to battery or ignition voltage in Light Blue/Orange wire (circuit No. 607) and Pink/Black wire (circuit No. 616). 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.
6. 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.
