VTSS Test 2A - VTSS Module No Response
WARNING: This page is about a different car, the 1995 Dodge Stratus and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform VTSS TEST 1A before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION in BODY CONTROL COMPUTER INTRODUCTION. Perform TEST VER-1A
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Disconnect BCM 20-pin connector and ensure connector is clean and not damaged. See Figure in CHIME TEST 3A. If BCM 20-pin connector terminal No. 1 is not used, vehicle is not equipped with VTSS. If BCM 20-pin connector terminal No. 1 has a Violet/Yellow wire, go to next step.
- Using scan tool in voltmeter mode, measure voltage at BCM 20-pin connector terminal No. 1 (Violet/Yellow wire). If scan tool voltage is less than 11 volts, go to VTSS TEST 3A. If scan tool voltage is greater than 11 volts, go to next step.
- Reconnect BCM 20-pin connector. Connect a jumper wire between BCM 20-pin connector terminal No. 1 (Violet/Yellow wire) and ground. Turn ignition on. Using scan tool, select BODY. Select BODY CONTROL MODULE and actuate VTSS. If VTSS did not actuate, replace BCM. If VTSS actuated, remove jumper wire and repeat VTSS TEST 1A .
