VTSS Test 6A - Headlight Circuit

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.
  1. Turn low beam headlights on. If headlights do not come on, check headlight power and ground circuits, headlight and dimmer switches, and/or broken headlight circuit connectors or splices. If headlights come on, turn headlights off. Turn ignition on. Using scan tool, read key in ignition switch status. If scan tool displays SWITCH: CLOSED, go to next step. If scan tool does not display SWITCH: CLOSED, go to VTSS TEST 6B.
  2. Using scan tool, actuate headlight relay. If headlights toggle on and off, replace BCM. If headlights do not toggle on and off, locate headlight delay relay in junction block. See Figure in CHIME TEST 3A. Remove headlight delay relay and ensure connector is clean and not damaged. Turn headlights on and go to next step.
  3. Using scan tool in voltmeter mode, check voltage on headlight delay relay cavity No. 5. See Figure in CHIME TEST 3A. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair open in headlight switch output circuit from junction block to splice.
  4. Turn headlights off. Using scan tool in voltmeter mode, check voltage on headlight delay relay cavity No. 3. See Figure in CHIME TEST 3A. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair Red/White wire between Power Distribution Center (PDC) and junction block.
  5. Using scan tool voltmeter, check voltage on headlight delay relay cavity No. 1. See Figure in CHIME TEST 3A. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, replace junction block.
  6. Turn ignition off and disconnect BCM. Using external ohmmeter, check resistance between BCM connector terminal No. 5 and headlight delay relay cavity No. 2. See Figure in CHIME TEST 3A. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, replace junction block.
  7. Install previously removed headlight delay relay. Using scan tool in voltmeter mode, check voltage on BCM connector terminal No. 5. See Figure in CHIME TEST 3A. If voltage is greater than 10 volts, replace BCM. If voltage is less than 10 volts, replace headlight delay relay.
