Test 34A: Orc, Passenger Squib 1 Circuit Open (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. Disconnect dual-stage passenger-side air bag module connector located above glove box. Connect SRS Load Tool (8443) to harness side of dual-stage passenger-side 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 PASSENGER SQUIB 1 CIRCUIT OPEN, go to next step. If DRB does not display PASSENGER SQUIB 1 CIRCUIT OPEN, replace dual-stage passenger-side air bag module. See DUAL-STAGE PASSENGER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION.
- 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 ORC adapter to harness side of ORC connector. Measure resistance between SRS load tool adapter and passenger-side air bag module connector terminal No. 1 (Black-Yellow wire). See Fig 1 . See WIRING DIAGRAMS . If resistance is less than one ohm, go to next step. If resistance is more than one ohm, repair open or high resistance in Black-Yellow wire.
- Measure resistance between SRS Load Tool adapter and passenger-side air bag module connector terminal No. 2. (Dark Green-Yellow wire). See Fig 1 . If resistance is less than one ohm and no other malfunctions are detected, replace ORC. If resistance is more than one ohm, repair open or high resistance in Dark Green-Yellow wire.
