Monitored & Set Conditions

The Speed Control Solenoid Circuits are monitored with the ignition key on, the speed control switched on, the SET switch pressed and the vehicle in drive gear moving above 35 MPH. The condition is set when the powertrain control module actuates the vacuum and vent solenoids but they do not respond. The Spd Ctrl Pwr Relay and S/C 12V Driver Ckt are monitored with the ignition key on and the speed control switched on. The condition is set when the speed control power supply circuit is either open or shorted to ground.
