Test 43A: Right SIACM, Curtain Squib Circuit Open (Active Code)
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.
- Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Remove right and left C-pillar trim panels. Remove rear shelf trim panel. Disconnect right curtain air bag module connector. Connect SRS Load Tool (8443) and appropriate jumper to harness side of right curtain air bag connector. Connect DRB to DLC. Turn ignition switch to ON position. Connect negative battery cable. Read right SIACM DTCs. If DRB displays RIGHT CURTAIN SQUIB CIRCUIT OPEN, go to next step. If DRB does not display RIGHT CURTAIN SQUIB CIRCUIT OPEN, replace right curtain air bag module. See CURTAIN (HEAD IMPACT) AIR BAG MODULE under REMOVAL & INSTALLATION.
- Turn ignition switch to OFF position. Disconnect negative battery terminal and wait at least 2 minutes. Access and disconnect right SIACM connector. See SIDE IMPACT AIR BAG CONTROL MODULE (SIACM) under REMOVAL & INSTALLATION. Connect SRS load tool adapter to right SIACM connector. Measure resistance of Light Blue-Yellow wire between SRS load tool adapter and harness side of right curtain air bag module connector. See WIRING DIAGRAMS . If resistance is less than one ohm, go to next step. If resistance is more than one ohm, repair open or high resistance in Light Blue-Yellow wire.
- Measure resistance of Light Blue-White wire between SRS load tool adapter and harness side of right curtain air bag module connector. If resistance is less than one ohm and no other malfunctions are detected, replace right side impact air bag control module. If resistance is more than one ohm, repair open or high resistance in Light Blue-White wire.
