Test TC-56C - Cruise Control Solenoid Circuits

NOTE: Perform TEST TC-56B  before proceeding. After each repair, perform TEST SC-VER  .
NOTE: For connector terminal identification, refer to CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAM  .
  1. Using DRB in voltmeter mode, check voltage on Powertrain Control Module (PCM) connector terminal No. 53 (Light Green/Red wire). If voltage is more than 10 volts, replace PCM. If voltage is less than 10 volts, disconnect and inspect cruise control servo 4-pin connector.
  2. If connector is not okay, repair connector as necessary. If connector is okay, turn ignition off. Using DRB in ohmmeter mode, check resistance of cruise control servo connector terminal No. 3 (Light Green/Red wire). If resistance is less than 5 ohms, repair short to ground in Light Green/Red wire.
  3. If resistance is more than 5 ohms, using an external ohmmeter, check resistance of Light Green/Red wire between PCM connector terminal No. 53 and cruise control servo connector terminal No. 3. If resistance is less than 5 ohms, replace cruise control servo. If resistance is more than 5 ohms, repair open in Light Green/Red wire.
