Test 145A - Repairing VTSS Indicator Light
NOTE:
Perform TEST 141A
before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION
. For wiring schematics, see WIRING DIAGRAMS
in this article. Perform TEST VER-3A - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Using scan tool, read VTSS status. If scan tool displays engine controller 1) NO RESPONSE / 2) NO RESPONSE, go to TEST 155A . If scan tool does not display engine controller 1) NO RESPONSE / 2) NO RESPONSE, go to next step.
- If VTSS indicator light stays on constantly, go to TEST 145B . If VTSS indicator light does not stay on, turn ignition switch to OFF position. Disconnect Body Control Module (BCM) Black connector. Ensure connector is clean and undamaged. BCM is located behind right kick panel. Connect jumper wire between terminal No. 10 (Black/Orange wire) on BCM Black connector and ground. If VTSS indicator light stays on, replace BCM. If indicator light does not stay on, go to next step.
- Disconnect Automatic Temperature Control (ATC) Sun Sensor/VTSS indicator light connector. Ensure connector is clean and undamaged. Using scan tool in voltmeter mode, measure voltage at terminal No. 1 (Pink wire) on ATC Sun Sensor/VTSS indicator light connector. If voltage is 10 volts or less, repair open Pink wire. If voltage is more than 10 volts, go to next step.
- Using an external ohmmeter, measure resistance between terminal No. 10 (Black/Orange wire) on BCM Black connector and terminal No. 2 on ATC Sun Sensor/VTSS indicator light connector. If resistance is 5 ohms or greater, repair open Black/Orange wire. If resistance is less than 5 ohms, replace VTSS indicator light.
