Test TC-55A - Cruise Control Switch Always Low

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST TC-1A  before proceeding. After each repair, perform TEST SC-VER  .
NOTE: For connector terminal identification, refer to CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAM  .
  1. Turn ignition switch to OFF position. Disconnect and inspect cruise control RES/ACCEL/SET/COAST switch 2-pin connector. If connector is not okay, repair connector as necessary. If connector is okay, using DRB in ohmmeter mode, check resistance of cruise control RES/ACCEL/SET/COAST switch connector terminal No. 1 (White wire).
  2. If resistance if more than 500 ohms, cruise control RES/ACCEL/SET/COAST switch is okay. Problem does not exist at this time. If resistance is less than 500 ohms, turn ignition switch to OFF position. Disconnect and inspect cruise control ON/CRUISE/OFF switch 2-pin connector. If connector is not okay, repair connector as necessary.
  3. If connector is okay, check resistance of cruise control ON/CRUISE/OFF switch connector terminal No. 1 (White wire). If resistance is more than 500 ohms, replace cruise control ON/CRUISE/OFF switch. If resistance is less than 500 ohms, turn ignition switch to OFF position. Disconnect and inspect clockspring 4-pin connector. If connector is not okay, repair connector as necessary.
  4. If connector is okay, check resistance of clockspring 4-pin connector terminal No. 2 (Red/Light Green wire). If resistance is more than 500 ohms, replace clockspring. If resistance is less than 500 ohms, turn ignition switch to OFF position.
  5. Disconnect and inspect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. If connector is not okay, repair connector as necessary. If connector is okay, use DRB to check resistance of clockspring 4-pin connector terminal No. 2 (Red/Light Green wire).
  6. If resistance is more than 500 ohms, replace PCM. If resistance is less than 500 ohms, repair short to ground in Red/Light Green wire.
