See SIDE IMPACT AIR BAG CONTROL MODULE (SIACM) under REMOVAL & INSTALLATION. Connect SRS Load Tool (8443) SIACM adapter to right SIACM harness connector. Turn ignition switch to ON position. Connect negative battery cable. Measure voltage between ground and right SIACM harness connector terminal No. 3 (Orange-Yellow wire). See Figure . If voltage is present, repair short to battery in Orange-Yellow wire. See WIRING DIAGRAMS . If voltage is not present, go to next step.
Measure voltage between ground and right SIACM harness connector terminal No. 4 (Yellow-Orange wire). If voltage is present, repair short to battery in Yellow-Orange wire. If voltage is not present and no other malfunctions are detected, replace right side impact air bag control module.
