Test 26A: Right 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. Right seat squib circuit wires change color at connector C208 (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 right side air bag module 4-pin connector C208 located at base of seat. Connect SRS Load Tool (8443) passenger cable and appropriate jumper to harness side of right side 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 SEAT SQUIB CIRCUIT SHORT, go to next step. If DRB does not display RIGHT SEAT SQUIB CIRCUIT SHORT, replace right 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 right SIACM connector. See SIDE IMPACT AIR BAG CONTROL MODULE (SIACM) under REMOVAL & INSTALLATION. Connect SRS Load Tool (8443) SIACM adapter to harness side of right SIACM connector. Measure resistance between SIACM connector terminals No. 3 (Orange-Yellow wire) and No. 4 (Yellow-Orange wire). See Figure . 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 right side impact air bag control module.
