Possible Causes

A passenger-side air bag module circuit shorted to battery or ignition could be caused by a short to battery or ignition in Light Blue/Orange wire (circuit No. 607), short to battery or ignition in Pink/Black wire (circuit No. 616), short to battery or ignition in passenger-side air bag module or an RCM internal fault.

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 DIAGNOSTIC TROUBLE CODES (DTCS)  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC C1925 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC C1925 was not retrieved, fault is intermittent. Go to step  5 .
2. 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. 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  5 .
   NOTE: Do not remove or separate shorting bars from RCM harness connector C2041A.
3. Check for short to battery
   
   Turn ignition switch to OFF position. Disconnect passenger-side air bag simulator from harness connector. Access RCM and disconnect harness connector C2041A. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Measure voltage between ground and harness side of RCM connector C2041A, terminal No. 6 (Light Blue/Orange wire). See Figure . Measure voltage between ground and harness side of RCM connector C2041A, terminal No. 7 (Pink/Black wire). If voltage is more than 0.2 volt in either circuit, repair short to battery or ignition in Light Blue/Orange or Pink/Black wires. Go to step  6 . If voltage is less than 0.2 volt in both circuits, go to next step.
4. Check passenger-side air bag module wiring
   
   Disconnect passenger-side air bag simulator from harness connector. Inspect all crimps, terminals, wires and connectors in circuit No. 607 (Light Blue/Orange wire) feeding RCM connector C2041A, terminal No. 6. See WIRING DIAGRAMS  . Inspect all crimps, terminals, wires and connectors in circuit No. 616 (Pink/Black wire) feeding RCM connector C2041A, terminal No. 7. Check for pinched wires and damaged connector pin terminals. If any damage is found, repair as necessary. Go to step  6 . If no damage is found, go to step  6 .
5. Check for intermittent fault
   
   If DTC retrieved in step  1 was an intermittent fault, check for cause of intermittent short to battery or ignition in Light Blue/Orange and Pink/Black wires. 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 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.
