Possible Causes

Driver-side air bag high resistance could be caused by poor connection or corrosion in driver-side air bag module circuits or clockspring, open circuit or high resistance in clockspring windings, open circuit or high resistance in wiring harness, open or high resistance in driver-side air bag module or an internal RCM fault.

  1. Check for hard or intermittent DTC

    Ensure ignition is off. 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 DIAGNOSTIC TROUBLE CODES (DTCS)  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1932 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1932 was not retrieved, fault is intermittent. Go to step  5 .

  2. Check driver-side air bag

    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 B1932 is retrieved, go to next step. If DTC B1932 is not retrieved, replace driver-side air bag module. Go to step  6 .
    NOTE: By disconnecting RCM connector, Gray-Orange and Gray-White wires are shorted together by shorting bar. Do not remove shorting bar.

  3. Check driver air bag module circuit

    Turn ignition switch to OFF position. Access RCM and disconnect harness connector. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Disconnect driver-side air bag simulator. Zero ohmmeter. Measure resistance between Gray-Orange and Gray-White wires on clockspring side of upper clockspring connector. If resistance is more than 0.5 ohm, go to next step. If resistance is less than 0.5 ohm, replace RCM. Go to step  6 .
    NOTE: By disconnecting clockspring connector, Gray-Orange and Gray-White wires are shorted together by shorting bar. Do not remove shorting bar.

  4. Check clockspring circuit

    Disconnect lower clockspring connector located on underside 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 than 0.5 ohm, repair Gray-Orange (circuit No. 614) or Gray-White wires (circuit No. 615) as necessary. See WIRING DIAGRAMS  . Go to step  6 . If resistance is more than 0.5 ohm, replace clockspring. See CLOCKSPRING  under REMOVAL & INSTALLATION. 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 Gray-Orange wire (circuit No. 614), Gray-White wire (circuit No. 615) 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 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 appropriate test. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION  table. DO NOT clear any DTCs until all DTCs have been resolved. 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 DIAGNOSTIC TROUBLE CODES (DTCS)  under DIAGNOSTICS.
