Possible Causes

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

  1. Check for hard or intermittent DTC

    Ensure ignition is off. Connect NGS tester to DLC. See USING NGS TESTER  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 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 off. Disable air bag system. See DISABLING SYSTEM  under DIAGNOSTICS. Turn ignition switch to RUN position. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1932 is retrieved, go to next step. If DTC B1932 is not retrieved, replace driver-side air bag module. See DRIVER-SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  6 .
    NOTE: By disconnecting RCM harness connector, circuits 15S-JA8 (Green/Red wire) and 91S-JA8 (Black/Orange wire) are shorted together by shorting bar. DO NOT remove shorting bar.

  3. Check driver-side air bag circuit

    Ensure ignition is off. Access RCM and disconnect harness connector. See RESTRAINTS CONTROL MODULE  under REMOVAL & INSTALLATION. Disconnect driver-side air bag simulator. Zero ohmmeter. Measure resistance between Green/Red and Black/Orange wires on clockspring side of upper clockspring connector. If resistance is more than 1.4 ohms, go to next step. If resistance is less than 1.4 ohms, check wiring harness for corrosion. If wiring harness is damaged, repair/replace as necessary. Go to step  6 . If wiring harness is okay, replace RCM. Go to step  6 .

  4. Check air bag clockspring

    Ensure ignition is off. Disconnect lower clockspring connector located at bottom of steering column. Measure resistance between Green/Red and Black/Orange wires on RCM side of lower clockspring connector. If resistance is less than 0.5 ohm, replace clockspring assembly. See CLOCKSPRING  under REMOVAL & INSTALLATION. Go to step  6 . If resistance is more than 0.5 ohm, repair Green/Red and/or Black/Orange wires as necessary. Go to step  6 .

  5. 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 high resistance on Green/Red wire, Black/Orange wire and clockspring. 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.

  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. 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. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
