Possible Causes

A driver-side air bag ignitor circuit shorted to battery or ignition voltage could be caused by a short to battery or ignition voltage in Gray/Orange wire (circuit No. 614), a short to battery or ignition voltage in Gray/White wire (circuit No. 615), a short to battery or ignition voltage in clockspring, a short to battery or ignition voltage 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 B1916 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1916 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 B1916 is retrieved, go to next step. If DTC B1916 is not retrieved, replace driver-side air bag module. See DRIVER-SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  6 .
   NOTE: Do not remove or separate shorting bars from RCM harness connector.
3. Check driver-side air bag circuit
   
   Turn ignition switch to 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. Turn ignition switch to RUN position. Measure voltage between ground and RCM harness connector terminals No. 3 (Gray/Orange wire) and No. 4 (Gray/White wire) separately. See Figure . If voltage is more than 0.2 volt in either wire, go to next step. If voltage is less than 0.2 volt in both wires, replace RCM. Go to step  6 .
4. Check driver-side air bag wiring & clockspring
   
   Disconnect lower clockspring connector located at bottom of steering column. Inspect all crimps, terminals, fuses, wires and connectors feeding RCM harness connector terminals No. 3 (Gray/Orange wire) and No. 4 (Gray/White wire), clockspring and clockspring connectors. See WIRING DIAGRAMS  . Also, check for pinched wires and damaged connector terminals. If any damage is found, repair/replace as necessary and go to step  6 . If no damage is found, 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 short to battery or ignition voltage in Gray/Orange wire, Gray/White wire and clockspring assembly. 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.
