Test 145A - Repairing VTSS Indicator Light

CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.

NOTE: Perform TEST 141A before proceeding with this test.

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 BCM Black connector terminal No. 10 (Black/Orange wire) 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, check voltage on ATC Sun Sensor/VTSS indicator light connector terminal No. 1 (Pink wire). If voltage is less than 10 volts, repair open Pink wire. If voltage is more than 10 volts, go to next step.
Using an external ohmmeter, check resistance of Black/Orange wire between BCM Black connector terminal No. 10 and ATC Sun Sensor/VTSS indicator light connector terminal No. 2. If resistance is more than 5 ohms, repair open Black/Orange wire. If resistance is less than 5 ohms, replace VTSS indicator light.
