Test 7A: Seat Squib Short To Ground

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. 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 SEAT SQUIB CIRCUIT SHORT TO GROUND 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 side air bag and disconnect harness connector. See SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Connect appropriate SRS load tool to side air bag harness connector. Turn ignition switch to ON position. Connect negative battery cable. Using DRBIII, read SIACM DTCs. If DRBIII displays SEAT SQUIB CIRCUIT SHORT TO GROUND, go to next step. If DRBIII does not display SEAT SQUIB CIRCUIT SHORT TO GROUND, replace faulty side 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. Measure resistance between ground and appropriate side air bag line 1 circuit on harness side of side air bag connector. See WIRING DIAGRAMS  . Measure resistance between ground and appropriate side air bag line 2 circuit on harness side of side air bag connector. If resistance is more than 10 k/ohms in both circuits, replace appropriate SIACM. If resistance is less than one 10 k/ohms in either circuit, repair short to ground in appropriate circuit.
