Test 33B - Checking For Open Key-In Light Circuit
WARNING: This page is about a different car, the 1994 Plymouth Voyager, 1994 Plymouth Grand Voyager, 1994 Dodge Grand Caravan, 1994 Dodge Caravan, and 1994 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
in this article. For wiring diagrams, see WIRING DIAGRAMS
in this article.
CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.
- Disconnect Blue Body Control Module (BCM) connector. BCM is located behind center console. Check connector, and clean or repair connector as necessary. Perform TEST VER-1B . If connector is okay, go to next step.
- Using DRB in voltmeter mode, check voltage on key-in light driver circuit (Yellow/Red wire) at Blue BCM connector terminal No. 19. If voltage is more than 10 volts, replace BCM. Perform TEST VER-1B. If voltage is less than 10 volts, go to next step.NOTE: Key-in ignition switch connector MUST remain connected during following steps.
- Gain access to key-in ignition switch connector. Using DRB in voltmeter mode, backprobe key-in light driver circuit (Yellow/Red wire) at key-in ignition switch connector terminal No. 4. If voltage is more than 10 volts, repair open Yellow/Red wire. Perform TEST VER-1B. If voltage is less than 10 volts, go to next step.
- Backprobe courtesy light switch output circuit (Pink/Light Blue wire) at key-in ignition switch connector terminal No. 3. If voltage is less than 10 volts, repair open Pink/Light Blue wire. Perform TEST VER-1B. If voltage is more than 10 volts, repair or replace key-ignition bulb or socket as necessary. Perform TEST VER-1B
