Test SC-4A - Cruise Control Brake 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
table. For wiring diagrams, see WIRING DIAGRAM
.
- Disconnect brakelight switch connector. Turn ignition switch to ON position. Using DRB in voltmeter mode, check voltage on brakelight switch connector terminal No. 3 (White/Pink wire). If voltage is less than 10 volts, go to step 3).
- If voltage is more than 10 volts, connect a jumper wire between brakelight switch connector terminals No. 3 (White/Pink wire) and No. 6 (Black/Light Green wire). Using DRB, read brake switch input status. If DRB displays BRAKE SWITCH RELEASED, replace brakelight switch. If DRB does not display BRAKE SWITCH RELEASED, repair open Black/Light Green wire.
- If voltage is less than 10 volts in step 1), turn ignition switch to OFF position. 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 DRB in ohmmeter mode, check resistance of PCM connector terminal No. 29 (White/Pink wire). If resistance is less than 5 ohms, repair short to ground in White/Pink wire. If resistance is more than 5 ohms, replace PCM.
