Test SC-1D - Checking Speed Control Operation

WARNING: This page is about a different car, the 1996 Eagle Vision, 1996 Dodge Intrepid, 1996 Chrysler New Yorker, 1996 Chrysler LHS, and 1996 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST SC-1A  before proceeding.
  1. Turn ignition off. Disconnect brake switch connector. Brake switch connector is located near top of brake pedal. Inspect brake switch connector for damaged or pushed out terminals. Repair as necessary. Perform TEST SC-VER . If wiring and connectors are okay, go to next step.
  2. Ensure scan tool is still actuating speed control vent solenoid. Using scan tool in voltmeter mode, check voltage of speed control power supply circuit at brake switch connector. Refer to the BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION . If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, go to step 4).
    BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION

    Application Wire Color
    Brake Switch Sense Circuit White/Pink
    Brake Switch Ground Circuit Black
    Speed Control Power Supply Circuit Yellow/Red
    Switched Speed Control Power Supply Circuit Dark Blue/Red
    Brake Light Switch Output Circuit White/Tan
    Fused B+ Circuit Pink/Dark Blue
  3. Turn ignition off. Using an external ohmmeter, check resistance of speed control power supply circuit between brake switch connector and speed control servo connector. Refer to the BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION  for wire color identification. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open switched speed control power supply circuit. Perform TEST SC-VER.
  4. Turn ignition off. Disconnect the Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of the speed control power supply circuit between the brake switch connector and PCM connector terminal No. 5. Refer to the BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION  for wire color identification. If resistance is less than 5 ohms, replace PCM. Perform TEST SC-VER . If resistance is 5 ohms or more, repair open speed control power supply circuit between brake switch connector and PCM. Perform TEST SC-VER .
