Possible Causes

Right-side air bag circuit high resistance could be caused by damaged White/Yellow wire, damaged Brown/Yellow wire, damaged right side air bag module or damaged 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 B1998 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1998 was not retrieved, fault is intermittent. Go to step  5 .
2. Check right 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. If DTC B1998 is not retrieved, replace right side air bag module. See SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  6 . If DTC B1998 is retrieved, go to next step.
   NOTE: By disconnecting RCM connector C2041B, circuit No. 1259 (White/Yellow wire) and No. 1260 (Brown/Yellow wire) are shorted together with shorting bar. Do not remove shorting bar.
3. Check right side air bag harness for high resistance
   
   Turn ignition switch to OFF position. Access and disconnect RCM connector C2041B. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Remove air bag simulator from floor harness connector. Zero ohmmeter. Measure resistance between White/Yellow wire and Brown/Yellow wire on RCM side of right side air bag module floor harness connector. If resistance is more than one ohm, repair open in appropriate wire and go to step  6 . See WIRING DIAGRAMS  . If resistance is less than one ohm, go to next step.
4. Check right side air bag circuit wiring
   
   Disconnect right side air bag module simulator from floor harness connector. Inspect all crimps, terminals, wires and connectors in White/Yellow wire between right side air bag module floor harness connector and RCM connector C2041B, terminal No. 5. See Figure . Inspect all crimps, terminals, wires and connectors in Brown/Yellow wire between right side air bag module floor harness connector and RCM connector C2041B, terminal No. 6. 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, replace RCM. Go to step  6 .
5. Check for intermittent fault
   
   Refer to continuous DTCs recorded in step  1 . If DTC retrieved in step  1 was a intermittent fault, check for cause of intermittent high resistance on White/Yellow wire (circuit No. 1259) and Brown/Yellow wire (circuit No. 1260). 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 a 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. DO NOT clear any DTCs until all DTCs have been resolved. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION  table. If no DTCs were retrieved, reconnect air bag system. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Prove out system. See PROVE OUT SYSTEM  under DIAGNOSTICS. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
