Test SC-2A - Cruise Control On/Off Switch
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 SC-1A
before proceeding with this test. After each repair, perform TEST VER-4A
.
- Turn ignition switch to ON position. Using scan tool, read cruise control switch voltage. If voltage is more than 4 volts, go to step 4). If voltage is less than 4 volts, disconnect cruise control SET/RESUME switch connector.
- Using scan tool, read cruise control switch voltage. If voltage is more than 4 volts, replace cruise control SET/RESUME switch. If voltage is less than 4 volts, turn ignition switch to OFF position.
- Disconnect Powertrain Control Module (PCM) 60-pin connector. PCM is located under air cleaner. Using scan tool in ohmmeter mode, check resistance of PCM 60-pin connector terminal No. 23 (Red/Light Green wire). If resistance is less than 5100 ohms, repair short to ground in Red/Light Green wire. If resistance is more than 5100 ohms, replace PCM.
- If voltage is more than 4 volts in step 1), disconnect cruise control ON/OFF switch. Connect a jumper wire between cruise control switch connector terminals No. 1 (Black wire) and No. 2 (White wire). Using scan tool, read cruise control switch voltage. If voltage is less than one volt, replace cruise control ON/OFF switch.
- If voltage is more than one volt, remove jumper wire. Using scan tool in voltmeter mode, check voltage on cruise control switch connector terminal No. 2 (White wire). If voltage is more than 4 volts, repair open Black wire. If voltage is less than 4 volts, replace PCM.
