Possible Causes

Right-side air bag circuit high resistance could be caused by damaged White/Yellow wire (circuit No. 1259), damaged Brown/Yellow wire (circuit No. 1260), damaged right side air bag module or 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 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  7 .
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 retrieved, go to step  5 . If DTC B1998 is not retrieved, go to next step.
3. Check right side air bag in-seat harness for high resistance
   
   Turn ignition switch to OFF position. Access and disconnect right side air bag module in-seat harness connector from air bag module. See SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Measure resistance in White/Yellow wire between seat harness side of right side air bag module floor connector and harness side of right side air bag module connector. If resistance is more than one ohm, repair open in White/Yellow wire. See WIRING DIAGRAMS  . Go to step  8 . If resistance is less than one ohm, go to next step.
4. Check right side air bag harness for high resistance
   
   Measure resistance of Brown/Yellow wire between right side air bag module floor harness connector and right side air bag module connector. If resistance is more than one ohm, repair open in Brown/Yellow wire. Go to step  8 . If resistance is less than one ohm, replace right side air bag module. Go to step  8 .
   NOTE: By disconnecting RCM connector C2004, circuit No. 1259 (White/Yellow wire) and No. 1260 (Brown/Yellow wire) are shorted together with shorting bar. Do not remove shorting bar.
5. Check right side air bag harness for high resistance
   
   Turn ignition switch to OFF position. Access RCM and disconnect harness connector C2004. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Remove right side air bag simulator from harness connector. Zero ohmmeter. Measure resistance between White/Yellow wire and Brown/Yellow wire on vehicle harness side of right side air bag module floor harness connector. If resistance is more than one ohm, repair open in appropriate wire. See WIRING DIAGRAMS  . Go to step  8 . If resistance is less than one ohm, go to next step.
6. Check right side air bag circuit to seat harness
   
   Inspect all crimps, terminals, wires and connectors in circuit No. 1259 (White/Yellow wire) between right side air bag module floor harness connector and RCM connector C2004, terminal No. 5. Inspect all crimps, terminals, wires and connectors in circuit No. 1260 (Brown/Yellow wire) between right side air bag module floor harness connector and RCM connector C2004, terminal No. 6. Also, check for pinched wires and damaged connector terminals. If any damage is found, repair or replace as necessary. Go to step  8 . If no damage is found, replace RCM. Go to step  8 .
7. 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 in White/Yellow and Brown/Yellow wires. 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.
8. 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. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
