Test 2A - No Response From Air Bag Control Module
- Remove and inspect fuse No. 4 from junction block. Junction block is behind right kick panel. If fuse is open, go to TEST 2B . If fuse is okay, go to next step.
- Using scan tool in voltmeter mode, measure voltage at voltage input side of fuse No. 4 socket. If voltage is 10 volts or less, repair open ignition switch output circuit. If voltage is more than 10 volts, go to next step.
- Turn ignition off and wait 2 minutes. Install fuse No. 4. Disconnect Air Bag System Control Module (ABSCM) connector. ABSCM is located under center console. Turn ignition on.
- Using scan tool in voltmeter mode, measure voltage at terminal No. 17 (Dark Blue/White wire) on ABSCM connector. If voltage is 10 volts or less, repair open Dark Blue/White wire. If voltage is more than 10 volts, go to next step.
- Turn ignition off. Using scan tool in ohmmeter mode, measure resistance at terminal No. 10 (Black/Pink wire) on ABSCM connector. If resistance is 15 ohms or greater, repair open Black/Pink wire. If resistance is less than 15 ohms, go to next step.
- Using scan tool in voltmeter mode, measure voltage at terminal No. 19 (Violet/Brown wire) on ABSCM connector. If voltage is not 1.8-2.6 volts, repair open Violet/Brown wire. If voltage is 1.8-2.6 volts, go to next step.
- Using scan tool in voltmeter mode, measure voltage at terminal No. 18 (White/Black wire) on ABSCM connector. If voltage is not 1.8-2.6 volts, repair open White/Black wire. If voltage is 1.8-2.6 volts, see the AIR BAG RESTRAINT SYSTEM article.
NOTE:
For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAM. Perform VERIFICATION TEST VER-1 after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
