Test 13A: Driver Squib 1 Circuit Open

WARNING: This page is about a different car, the 2004 Dodge Dakota. 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.
  1. Turn ignition switch to ON position. Using DRBIII, determine if DRIVER SQUIB 1 CIRCUIT OPEN is an active or stored Diagnostic Trouble Code (DTC). If DRIVER SQUIB 1 CIRCUIT OPEN is an active DTC, go to next step. If DRIVER SQUIB 1 CIRCUIT OPEN is a stored DTC, go to TEST 1B: REPAIRING STORED CODES .
  2. 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 appropriate SRS load tool to driver-side air bag module harness connectors. Turn ignition switch to ON position. Connect negative battery cable. On DRBIII, read active DTCs. If DRBIII displays DRIVER SQUIB 1 CIRCUIT OPEN, go to next step. If DRBIII does not display DRIVER SQUIB 1 CIRCUIT OPEN, replace driver-side air bag module.
  3. Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access clockspring and disconnect lower clockspring harness connector. See CLOCKSPRING  under REMOVAL & INSTALLATION. Connect appropriate SRS load tool to harness side of lower clockspring connector. Turn ignition switch to ON position. Connect negative battery cable. On DRBIII, read active DTCs. If DRBIII displays DRIVER SQUIB 1 CIRCUIT OPEN, go to next step. If DRBIII does not display DRIVER SQUIB 1 CIRCUIT OPEN, replace clockspring.
  4. Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access and disconnect Air Bag Control Module (ACM) connector. See AIR BAG CONTROL MODULE (ACM)  under REMOVAL & INSTALLATION. Connect appropriate SRS load tool adapter to harness side of ACM connector. Remove load tool from lower clockspring harness connector. Measure resistance in driver-side air bag module line 1 circuit (Black/Light Blue wire) between load tool adapter and clockspring connector. See WIRING DIAGRAMS . Measure resistance in driver-side air bag module line 2 circuit (Dark Green/Light Blue wire) between load tool adapter and clockspring connector. 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.
