Test 11A: Orc, Driver Squib 1 Circuit Short To Battery (Active Code)
NOTE:
Prior to performing any air bag system test, go to PRETEST INSPECTION & DIAGNOSTIC PROCEDURE
under DIAGNOSTICS. Perform TEST VER-1: AIR BAG VERIFICATION TEST
after all repairs unless otherwise directed.
- Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Remove driver-side air bag module. See DRIVER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION. Connect SRS Load Tool (8310) Brown cable and appropriate jumper to clockspring side of clockspring-to-air bag module connector. Connect DRB to DLC. Turn ignition switch to ON position. Connect negative battery cable. On DRB display, read active air bag DTCs. If DRB displays DRIVER SQUIB 1 CIRCUIT SHORT TO BATTERY, go to next step. If DRB does not display DRIVER SQUIB 1 CIRCUIT SHORT TO BATTERY, replace driver-side air bag module.
- Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access and disconnect clockspring lower connector. See CLOCKSPRING under REMOVAL & INSTALLATION. Connect SRS Load Tool (8310) Black cable and appropriate jumper to harness side of clockspring lower connector. Turn ignition switch to ON position. Connect negative battery cable. On DRB display, read active air bag DTCs. If DRB displays DRIVER SQUIB 1 CIRCUIT SHORT TO BATTERY, go to next step. If DRB does not display DRIVER SQUIB 1 CIRCUIT SHORT TO BATTERY, replace clockspring.
- Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access and disconnect ORC connector. See OCCUPANT RESTRAINT CONTROLLER (ORC) under REMOVAL & INSTALLATION. Connect SRS Load Tool (8310) ORC adapter to harness side of ORC connector. Turn ignition switch to ON position. Connect negative battery cable. Measure voltage in Black-Light Blue wire between ground and harness side of clockspring lower connector. See WIRING DIAGRAMS . If voltage is less than 0.5 volt, go to next step. If voltage is more than 0.5 volt, repair short to battery in Black-Light Blue wire.
- Measure voltage in Dark Green-Light Blue wire between ground and harness side of clockspring lower connector. If voltage is less than 0.5 volt and no other malfunctions are detected, replace ORC. If voltage is more than 0.5 volt, repair short to battery in Dark Green-Light Blue wire.
