Test 26A: Passenger Squib 2 Circuit Open
WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
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.
Air Bag Control Module (ACM) harness connectors C2 and C2 are identical, except for wire colors and terminal usage. See WIRING DIAGRAMS .

- Turn ignition switch to ON position. Using DRBIII, determine if PASSENGER SQUIB 2 CIRCUIT OPEN is active or stored Diagnostic Trouble Code (DTC). If PASSENGER SQUIB 2 CIRCUIT OPEN is an active DTC, go to next step. If PASSENGER SQUIB 2 CIRCUIT OPEN is a stored DTC, go to TEST 1B: REPAIRING STORED CODES .
- Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Access passenger-side air bag module and disconnect harness connector. See DUAL-STAGE PASSENGER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION. Connect appropriate SRS load tool to passenger-side air bag module harness connector. Turn ignition switch to ON position. Connect negative battery cable. On DRBIII, read active DTCs. If DRBIII displays PASSENGER SQUIB 2 CIRCUIT OPEN, go to next step. If DRBIII does not display PASSENGER SQUIB 2 CIRCUIT OPEN, replace passenger-side air bag module.
- Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access Air Bag Control Module (ACM) and disconnect harness connector C2. See AIR BAG CONTROL MODULE (ACM) under REMOVAL & INSTALLATION. Connect appropriate SRS load tool adapter to harness side of ACM connector C2. Remove load tool from passenger-side air bag harness connector. Measure resistance in Tan/Yellow wire (line 2 circuit) between load tool adapter and passenger-side air bag connector terminal No. 3. See Figure . Measure resistance in Orange/Yellow wire (line 1 circuit) between load tool adapter and passenger-side air bag connector terminal No. 4. If resistance is less than one ohm in both circuits, replace ACM. If resistance is more than one ohm in either circuit, repair open or high resistance in appropriate wire. See WIRING DIAGRAMS .
