Test 4A: Curtain Squib Circuit Open

WARNING: This page is about a different car, the 2002 Dodge Durango and 2002 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 CURTAIN SQUIB CIRCUIT OPEN is active or stored Diagnostic Trouble Code (DTC). If left or right Side Impact Air Bag Control Module (SIACM) is generating an active DTC, go to next step. If left or right SIACM is generating a stored DTC, go to TEST 1B: REPAIRING STORED CODES  .
  2. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Access appropriate curtain air bag and disconnect harness connector. See CURTAIN (HEAD IMPACT) AIR BAG MODULE  under REMOVAL & INSTALLATION. Connect appropriate SRS load tool to curtain air bag harness connector. Turn ignition switch to ON position. Connect negative battery cable. Using DRBIII, read SIACM DTCs. If DRBIII displays CURTAIN SQUIB CIRCUIT OPEN, go to next step. If DRBIII does not display CURTAIN SQUIB CIRCUIT OPEN, replace faulty curtain air bag module.
  3. Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access appropriate SIACM and disconnect harness connector. See SIDE IMPACT AIR BAG CONTROL MODULE (SIACM)  under REMOVAL & INSTALLATION. Connect appropriate SRS load tool adaptor to SIACM harness connector. Disconnect SRS load tool from curtain air bag harness connector. Measure resistance in appropriate curtain air bag line 1 circuit between load tool adaptor and curtain air bag harness connector. See WIRING DIAGRAMS  . Measure resistance in appropriate curtain air bag line 2 circuit between load tool adaptor and curtain air bag harness connector. If resistance is less than one ohm in both circuits, replace appropriate SIACM. If resistance is more than one ohm in either circuit, repair open in appropriate circuit.
