Test TC-54A - Cruise Control Switch Always Low

WARNING: This page is about a different car, the 1995 Eagle Vision, 1995 Dodge Intrepid, and 1995 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST TC-1A  before proceeding with this test. After each repair, perform TEST VER-4A  .
  1. Turn ignition OFF. Disconnect and inspect cruise control SET/RESUME switch 2-pin connector. If connector is not okay, repair connector as necessary. If connector is okay, using scan tool in ohmmeter mode, check resistance of cruise control SET/RESUME switch connector terminal No. 2 (White wire).
  2. If resistance if more than 500 ohms, cruise control SET/RESUME switch is okay. Problem does not exist at this time. If resistance is less than 500 ohms, turn ignition OFF. Disconnect and inspect cruise control ON/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/OFF switch connector terminal No. 2 (White wire). If resistance is more than 500 ohms, replace cruise control ON/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, using scan tool in ohmmeter mode, check resistance of clockspring 4-pin connector terminal No. 2 (Red/Light Green wire). 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.
