Test TC-52A - Cruise Control Power Relay Circuit
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 TC-1A
before proceeding with this test. After each repair, perform TEST VER-4A
.
- Turn ignition switch to OFF position. Remove cruise control relay from junction block. See Figure . Junction block is located under left side of dash behind kick panel. Inspect relay connector. If connector is not okay, repair connector as necessary.
- If connector is okay, turn ignition switch to ON position. Using scan tool in voltmeter mode, check voltage on cruise control relay connector terminal No. 16 (Dark Blue/White wire). If voltage is less than 10 volts, go to TEST TC-52B .
- If voltage is more than 10 volts, using an external ohmmeter, check resistance between cruise control relay connector terminals No. 16 and No. 17. See Figure . If resistance is more than 100 ohms, replace cruise control relay.
- If resistance is less than 100 ohms, 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 an external ohmmeter, check resistance of Tan/Red wire between PCM connector terminal No. 55 and cruise control relay connector terminal No. 17.
- If resistance is more than 5 ohms, repair open in Tan/Red wire. If resistance is less than 5 ohms, turn ignition switch to OFF position. Using scan tool in ohmmeter mode, check resistance of PCM connector terminal No. 55 (Tan/Red wire).
- If resistance is more than 5 ohms, replace PCM. If resistance is less than 5 ohms, repair short to ground in Tan/Red wire.
