Test 22A: ACM, Passenger Squib Circuit Short To Battery (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. Disconnect passenger-side air bag module connector located above glove box. Connect SRS Load Tool (8310) Brown cable and appropriate jumper to harness side of passenger-side air bag module connector. Connect DRB to DLC. Turn ignition switch to ON position. Connect negative battery cable. On DRB display, read active air bag DTCs. If DRB displays PASSENGER SQUIB CIRCUIT SHORT TO BATTERY, go to next step. If DRB does not display PASSENGER SQUIB CIRCUIT SHORT TO BATTERY, replace passenger-side air bag module. See PASSENGER-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 ACM connector. See AIR BAG CONTROL MODULE (ACM) under REMOVAL & INSTALLATION. Connect SRS Load Tool (8310) ACM adapter to harness side of ACM connector. Turn ignition switch to ON position. Connect negative battery cable. Measure voltage in Black-Yellow wire between ground and harness side of passenger-side air bag module connector. If voltage is less than 0.5 volt, go to next step. If voltage is more than 0.5 volt, repair short to battery in Black-Yellow wire. See WIRING DIAGRAMS .
- Measure voltage between ground and harness side of passenger-side air bag module connector Dark Green-Yellow wire. If voltage is less than 0.5 volt and no other malfunctions are detected, replace ACM. If voltage is more than 0.5 volt, repair short to battery in Dark Green-Yellow wire.
