Test SC-1C - Checking Speed Control Operation
WARNING: This page is about a different car, the 1996 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform TEST SC-1A before proceeding.
- Inspect throttle cable. If throttle cable is damaged or misadjusted, repair as necessary. Perform TEST SC-VER. If throttle cable is okay, go to next step.
- Turn ignition off. Disconnect speed control servo connector. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of speed control vacuum solenoid control circuit between PCM connector terminal No. 78 and speed control servo connector. See SPEED CONTROL SERVO 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 speed control vacuum solenoid control circuit. Perform TEST SC-VER.
- Using an external ohmmeter, check resistance of speed control vent solenoid control circuit between PCM connector terminal No. 80 and speed control servo connector. See SPEED CONTROL SERVO CONNECTOR WIRE IDENTIFICATION table for wire color identification. If resistance is less than 5 ohms, replace speed control servo. Perform TEST SC-VER. If resistance is 5 ohms or more, repair open speed control vent solenoid control circuit. Perform TEST SC-VER.
