Test 76A - Inoperative Key-In Lamp

WARNING: This page is about a different car, the 1997 Eagle Vision, 1997 Dodge Intrepid, 1997 Chrysler LHS, and 1997 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST 75A  before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION  . For wiring schematics, see WIRING DIAGRAMS  in this article. Perform TEST VER-1 - VERIFICATION PROCEDURE  after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Turn ignition off. Close all doors, wait 60 seconds. Open and close left front door. If key-in lamp illuminates, then goes off after 30 seconds, system is operating properly at this time. If key-in lamp does not illuminate, and courtesy lamps do not illuminate when left front door is open, go to TEST 34A  . If courtesy lamps illuminate when left front door is open, go to next step.
  2. Turn ignition on. Using scan tool, actuate key-in lamp. If key-in lamp flashes on and off, replace BCM. If key-in lamp does not flash on and off, go to next step.
  3. Using scan tool, stop key-in lamp actuation. Remove key-in lamp and inspect key-in lamp and socket. If lamp is open or socket is damaged, repair as necessary. If lamp and socket are okay, go to next step.
  4. Reinstall key-in lamp. Disconnect key-in lamp connector (on steering column). Using scan tool in voltmeter mode, measure voltage at terminal No. 1 (Pink wire) on key-in lamp connector. If voltage is 10 volts or less, repair open Pink wire. If voltage is more than 10 volts, go to next step.
  5. Reconnect key-in lamp connector. Disconnect Body Control Module (BCM) Bone connector. BCM is located behind right kick panel. Using scan tool in voltmeter mode, measure voltage at terminal No. 5 (Yellow/Red wire) on BCM Bone connector. If voltage is more than 10 volts, replace BCM. If voltage is 10 volts or less, go to next step.
  6. Disconnect key-in lamp connector (on steering column). Using an external ohmmeter, measure resistance between terminal No. 2 (Yellow/Red wire) on key-in lamp connector and terminal No. 5 on BCM Bone connector. If resistance is 5 ohms or greater, repair open Yellow/Red wire. If resistance is less than 5 ohms, replace key-in lamp assembly.
