VTSS Test 7A - VTSS Indicator Light Driver Circuit
NOTE:
Perform VTSS TEST 1A
before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION
. For wiring diagrams, refer to WIRING DIAGRAMS
. Perform, after each repair, VERIFICATION TEST VER-1A - VERIFICATION PROCEDURE
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition on. Once BCM has completed light check, determine if VTSS indicator light is on. If light is illuminated, go to VTSS TEST 7B . If light is not illuminated, go to next step.
- Turn ignition off. Disconnect Body Control Module (BCM) connector "A". BCM is located with junction block under driver's side instrument panel. See Figure . Connect jumper wire between ground and terminal No. 16 (Black/Orange wire) on connector "A". If VTSS indicator light illuminates, replace BCM. If light does not illuminate, go to next step.
- Disconnect information center harness connector. Inspect circuit board. Replace as needed. Remove VTSS indicator light bulb. Replace bulb as needed. Go to next step.
- Using scan tool in voltmeter mode, measure voltage at terminal No. 12 (Pink wire) on information center connector. If voltage is more than 10 volts, repair open Black/Orange wire between information center and BCM. If voltage is 10 volts or less, repair open Pink wire.
