Possible Causes

WARNING: This page is about a different car, the 2003 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

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, open or high 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 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. 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 614 (Gray/Orange wire) and 615 (Gray/White wire) are shorted together by shorting bar. Do not remove shorting bar.
  3. Check driver-side air bag circuit

    Ensure ignition switch is in OFF position. Access RCM and disconnect harness connector. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. 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 more than 0.5 ohm, go to next step. If resistance is less than 0.5 ohm, replace RCM. Go to step  6 .
  4. Check clockspring

    Ensure ignition switch is in OFF position. Disconnect lower clockspring connector located at bottom of steering column. Measure resistance between Gray/Orange and Gray/White 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 appropriate wire. 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 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.
  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.
