Test SC-52C - Code 34, Cruise Control Vent Solenoid Control Circuit

NOTE: Perform TEST SC-52B before proceeding.

Put DRB-II in voltmeter mode. Using DRB-II, check voltage at Powertrain Control Module (PCM) 60-pin connector terminal No. 53, vent solenoid control circuit (Light Green/Red wire). If voltage is more than 10 volts, replace PCM. Perform VERIFICATION PROCEDURE SC-VER . If voltage is less than 10 volts, disconnect and inspect cruise control servo 4-pin connector.
If connector is not okay, repair connector as necessary. Perform VERIFICATION PROCEDURE SC-VER . If connector is okay, turn ignition off. Put DRB-II in ohmmeter mode. Using DRB-II, check resistance at cruise control servo connector terminal No. 3, vent solenoid control circuit (Light Green/Red wire). If resistance is less than 5 ohms, repair short to ground in Light Green/Red wire. Perform VERIFICATION PROCEDURE SC-VER .
If resistance is more than 5 ohms, using an external ohmmeter, check resistance of vent solenoid control circuit (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. Perform VERIFICATION PROCEDURE SC-VER . If resistance is more than 5 ohms, repair open in Light Green/Red wire. Perform VERIFICATION PROCEDURE SC-VER .
