Test TC-87A - Speed Control Switch Always Low

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.
  1. Turn ignition off. Disconnect 2-pin SET/RESUME switch connector (located behind speed control SET/RESUME switch). Using scan tool in ohmmeter mode, check resistance of 2-pin SET/RESUME switch connector signal circuit Red/Light Green wire. If resistance is less than 500 ohms, go to next step. If resistance is 500 ohms or more, speed control switches are in normal range. No problem exists at this time. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  2. Disconnect 2-pin ON/OFF switch connector (located behind speed control ON/OFF switch). Using scan tool in ohmmeter mode, check resistance of 2-pin ON/OFF switch connector signal circuit Red/Light Green wire. If resistance is less than 500 ohms, go to next step. If resistance is 500 ohms or more, replace ON/OFF switch. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  3. Disconnect 4-pin clockspring connector. Using scan tool in ohmmeter mode, check resistance of speed control switch signal circuit at clockspring connector. See CLOCKSPRING CONNECTOR WIRE IDENTIFICATION  table. If resistance is less than 500 ohms, go to next step. If resistance is 500 ohms or more, replace clockspring. Perform TEST VSS-VER - ROAD TEST VERIFICATION .
  4. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of speed control switch signal circuit between 4-pin clockspring connector and PCM connector terminal No. 41. See CLOCKSPRING CONNECTOR WIRE IDENTIFICATION  table. If resistance is less than 500 ohms, repair short to ground on speed control switch signal circuit. Perform TEST SC-VER - SPEED CONTROL VERIFICATION . If resistance is 500 ohms or more, replace PCM. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
