Possible Causes

Passenger-side air bag low resistance could be caused by short in wiring harness, low resistance in passenger-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). Turn ignition switch to ON 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 B1935 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1935 was not retrieved, fault is intermittent. Go to step  5 .
2. Check passenger-side air bag
   
   Turn ignition switch to ON position. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1935 is retrieved, go to next step. If DTC B1935 is not retrieved, replace passenger-side air bag module. See PASSENGER-SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  6 .
3. Check RCM circuits
   
   Access RCM and disconnect harness connector C2041. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Measure resistance between component side of RCM connector terminals No. 3 and 4. See Figure . If resistance is more 10 k/ohms, repair low resistance in Light Blue/Orange and Pink/Black wires. Go to step  6 . If resistance is less than 10 k/ohms, replace RCM. Go to step  6 .
4. Check circuits between passenger-side air bag & RCM
   
   Turn ignition switch to OFF position. Disconnect air bag simulator from passenger-side air bag harness connector. Measure resistance between Light Blue/Orange and Pink/Black wires on harness side of passenger-side air bag module harness connector. If resistance is less than 10 k/ohms, repair low resistance in Light Blue/Orange and/or Pink/Black wires. See WIRING DIAGRAMS  . Go to step  6 . If resistance is more than 10 k/ohms, replace RCM. Go to step  6 .
5. Check for intermittent fault
   
   Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Turn ignition switch to ON position. Perform on-demand self-test. If DTC B1935 was retrieved during on-demand self-test, check for intermittent fault at or near affected air bag or connector. Repair any intermittent problems found. If intermittent problems are found and repaired, go to next step. If intermittent problems are not found, go to step  4 . If DTC B1935 was not retrieved, check for cause of intermittent fault. Attempt to recreate fault by flexing wire harness and cycling ignition switch frequently. Activate systems in same wire harness. See WIRING DIAGRAMS  . Repair any intermittent problems found. 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 continuous DTCs were retrieved, reconnect air bag system. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Perform system operation check. See SYSTEM OPERATION CHECK  . Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
