Possible Causes

Driver-side air bag low resistance could be caused by short circuit in clockspring windings, short circuit in wiring harness, low resistance in driver-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 B1934 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1934 was not retrieved, fault is intermittent. Go to step  6 .
   NOTE: Shorting bars may be accessed by prying out Blue cover from harness side of connector.
2. Check RCM connector
   
   Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Access Restraints Control Module (RCM) and disconnect connector. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Inspect RCM, component side of connector, for worn or damaged camming beam and/or any foreign material. See Figure . Inspect RCM connector for worn, damaged or dislodged shorting bars. If camming beams and shorting bars are okay, go to next step. If camming beams and shorting bars are defective, repair or replace as necessary and go to step  7 .
3. Check driver-side air bag
   
   Turn ignition switch to RUN position. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1934 is retrieved, go to next step. If DTC B1934 is not retrieved, replace driver-side air bag module. See DRIVER-SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  7 .
   NOTE: By disconnecting RCM connector, Gray/Orange and Gray/White wires are shorted together by shorting bar. Do not remove shorting bar.
4. Check driver-side air bag circuit
   
   Turn ignition switch to OFF position. Disconnect air bag simulator from driver-side air bag harness connector. Zero ohmmeter. Measure resistance between Gray/Orange and Gray/White wires on harness side of upper clockspring connector. If resistance is less than 10 k/ohms, go to next step. If resistance is more than 10 k/ohms, replace RCM. Go to step  7 .
   NOTE: By disconnecting lower clockspring harness connector, connector terminals are shorted together by shorting bar. Do not remove shorting bar.
5. Check clockspring
   
   Disconnect lower clockspring connector located at bottom of steering column. Zero ohmmeter. Measure resistance between Gray/Orange and Gray/White wires on RCM side of lower clockspring connector. If resistance is less 10 k/ohms, repair Gray/Orange and/or Gray/White wires as necessary. See WIRING DIAGRAMS  . Go to step  7 . If resistance is more than 10 k/ohms, replace clockspring assembly. See CLOCKSPRING  under REMOVAL & INSTALLATION. Go to step  7 .
6. Check for intermittent fault
   
   Refer to continuous DTCs recorded in step  1 . If DTC retrieved in step  1 was an intermittent fault, check for cause of intermittent low resistance in Gray/Orange wire, Gray/White wire and clockspring. 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.
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 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.
