Test 5A: Left SIACM, Seat Squib Circuit Short (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. Left seat squib circuit wires change color at connector C209 (Orange-Yellow becomes White and Yellow-Orange becomes Orange). See WIRING DIAGRAMS .

Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Disconnect left side air bag module 4-pin connector C209 located at base of seat. Connect SRS Load Tool (8443) passenger 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. Connect SRS Load Tool (8443) SIACM adapter to harness side of left SIACM connector. Measure resistance between SIACM connector terminals No. 3 (Orange-Yellow wire) and No. 4 (Yellow-Orange wire). If resistance is less than 5 ohms, repair short in wiring harness between Orange-Yellow and Yellow-Orange 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.
