Possible Causes

Driver-side air bag circuit failure can be caused by a short to ground or battery in circuits No. 614 (Gray/Orange wire) or No. 615 (Gray/White wire), short to ground or battery in clockspring or short to ground or battery in driver-side air bag module.

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 B1915 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1915 was not retrieved, fault is intermittent. Go to step  6.
2. Check driver-side air bag module
   
   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 B1915 is retrieved, go to next step. If DTC B1915 is not retrieved, replace driver-side air bag module. Go to step  7.
   NOTE: Do not separate or remove shorting bars from ECS module connector.
3. Check driver-side air bag circuit for short to ground
   
   Turn ignition switch to OFF position. Access and disconnect ECS module harness connector. See ELECTRONIC CRASH SENSOR (ECS) MODULE  under REMOVAL & INSTALLATION. Measure resistance between harness side of ECS module connector terminals No. 1 (Gray/Orange wire) and No. 21 (Black/Light Blue wire, circuit No. 875). See Figure. If resistance is less than 10 k/ohms, repair short to ground in Gray/Orange or Gray/White wire. See WIRING DIAGRAMS . Go to step  7. If resistance is more than 10 k/ohms, go to next step.
   NOTE: Do not separate or remove shorting bars from ECS module connector.
4. Check driver-side air bag circuit for short to battery
   
   Turn ignition switch to RUN position. Measure voltage between ground and harness side of ECS module connector terminal No. 1 (Gray/Orange wire). If voltage is more than 0.2 volt, repair short to battery in Gray/Orange or Gray/White wire. Go to step  7. If voltage is less than 0.2 volt, go to next step.
5. Check driver-side air bag circuits & clockspring
   
   Disconnect air bag simulator from upper clockspring connector. Access and disconnect lower clockspring harness connector. See CLOCKSPRING  under REMOVAL & INSTALLATION. Inspect all crimps, terminals, wires and connectors in circuits 614 (Gray/Orange wire) and 615 (Gray/White wire) feeding ECS module connector and upper and lower clockspring connectors. See WIRING DIAGRAMS . Check for pinched wires and damaged connector pins and terminals. If damage is found, repair/replace as necessary. Go to step  7. If no damage was found, go to next step.
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 causes of intermittent short to ground or battery in circuit No. 614 (Gray/Orange wire) and circuit No. 615 (Gray/White wire) and clockspring assembly. See WIRING DIAGRAMS . Attempt to recreate fault by flexing wire harness and cycling ignition key frequently. Repair any intermittent problems. Go to next step. If no intermittent problems are found, 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. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION  table. DO NOT clear any DTCs until all DTCs have been resolved. 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.
