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 left front seat back cover and reposition seat back cushion material to access seat air bag module connector. Disconnect left side air bag module connector. Connect SRS Load Tool (8310) Brown cable and appropriate jumper to harness side of left side air bag connector. Connect DRB to DLC. Turn ignition switch to ON position. Connect negative battery cable. Read left SIACM DTCs. If DRB displays LEFT SEAT SQUIB CIRCUIT SHORT, go to next step. If DRB does not display LEFT SEAT SQUIB CIRCUIT SHORT, replace left side air bag module. See SIDE AIR BAG MODULE under REMOVAL & INSTALLATION.
- Turn ignition switch to OFF position. Disconnect negative battery cable and wait at least 2 minutes. Access and disconnect left SIACM connector. See SIDE IMPACT AIR BAG CONTROL MODULE (SIACM) under REMOVAL & INSTALLATION. Measure resistance between SIACM connector terminals No. 3 (Light Green-Orange wire) and No. 4 (Light Green-White wire). If resistance is less than 5 ohms, repair short in wiring harness between left side seat squib Light Green-Orange and Light Green-White wires. See WIRING DIAGRAMS . If resistance is more than 5 ohms and no other malfunctions are detected, replace left side impact air bag control module.
