Test SC-2A - Cruise Control On/Off Switch
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 SC-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
.
- Turn ignition switch to ON position. Using DRB, 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 DRB, 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) connector. PCM is located under air cleaner. Using DRB in ohmmeter mode, check resistance of PCM 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 DRB, 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 DRB 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.
