Possible Causes

Right-side air bag circuit low 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, damaged RCM or damaged shorting bar or camming beam in RCM connector C2004 or right side air bag module floor harness connector.

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 B1999 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1999 was not retrieved, fault is intermittent. Go to step  6 .
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 B1999 is retrieved, go to step  5 . If DTC B1999 is not retrieved, go to next step.
3. Check right side air bag harness
   
   Turn ignition switch to OFF position. Ensure RCM connector C2004 is connected. Remove right side air bag simulator from harness connector. 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 10 k/ohms, go to next step. If resistance is less than 10 k/ohms, repair short between White/Yellow and Brown/Yellow wires. See WIRING DIAGRAMS  . Go to step  7 .
4. Check right side air bag harness
   
   Inspect all crimps, terminals, wires and connectors in circuit No. 1259 (White/Yellow wire) between 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 floor harness connector and RCM connector C2004, terminal No. 6. If any damage is found, repair as necessary. Go to step  7 . If no damage is found, replace RCM. Go to step  7 .
5. Check right side air bag harness
   
   Turn ignition switch to OFF position. Connect RCM connector C2004. Connect right side air bag module floor harness connector. Access and disconnect right side air bag module connector from air bag module. See SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Measure resistance between White/Yellow wire and Brown/Yellow wire on vehicle harness side of right side air bag module connector. If resistance is more than 10 k/ohms, replace right side air bag module. Go to step  7 . If resistance is less than 10 k/ohms, repair short between White/Yellow and Brown/Yellow wires (between right side air bag module connector and floor harness connector). See WIRING DIAGRAMS  . Go to step  7 .
6. 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 low 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.
7. 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.
