Test 5A: Curtain Squib Circuit Short
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.
- Turn ignition switch to ON position. Using DRBIII, determine if CURTAIN SQUIB CIRCUIT SHORT 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 .
- 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 SHORT, go to next step. If DRBIII does not display CURTAIN SQUIB CIRCUIT SHORT, replace faulty curtain air bag module.
- 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 between appropriate curtain air bag line 1 and line 2 circuits on harness side of curtain air bag harness connector. See WIRING DIAGRAMS . If resistance is more than 10 k/ohms, replace appropriate SIACM. If resistance is less than 10 k/ohms, repair short between appropriate circuits.
