Test SC-1D - Checking Speed Control Operation

WARNING: This page is about a different car, the 1996 Plymouth Breeze, 1996 Dodge Stratus, 1996 Chrysler Cirrus, 1995 Dodge Stratus, and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST SC-1A - CHECKING SPEED CONTROL OPERATION  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 - SPEED CONTROL VERIFICATION . 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. See BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION  table. 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 JA Body White/Red
    Brake Switch Ground Circuit JA Body Black/Light Green
    Speed Control Power Supply Circuit JA Body Yellow/Pink
    Switched Speed Control Power Supply Circuit JA Body Dark Blue/Red
    Brake Light Switch Output Circuit JA Body White/Tan
    Fused B+ Circuit JA Body Red/Black
  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. See BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION  table 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 - SPEED CONTROL VERIFICATION .
  4. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of speed control power supply circuit between brake switch connector and PCM connector terminal No. 5. See BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION  table for wire color identification. If resistance is less than 5 ohms, replace PCM. Perform TEST SC-VER - SPEED CONTROL VERIFICATION . If resistance is 5 ohms or more, repair open speed control power supply circuit between brake switch connector and PCM. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
