Normal Operation
The speed control actuator receives a signal from the speed control switches through circuit 8-PG13 (WH) and sends a return signal through circuit 9-PG13 (BN). Voltage is supplied to the speed control switches through circuit 15-PG13 (GN/YE). Voltage to the speed control actuator is supplied through circuit 15-PG12 (GN/WH) from the battery junction box (BJB). Ground for the speed control actuator is supplied through circuit 91-PG12 (BK/WH).
The speed control actuator adjusts the speed control cable, which controls the throttle body.
Voltage is supplied to the speed control deactivator switch through circuit 15-PG6 (GN/YE). The speed control deactivator switch sends a voltage signal through circuit 15S-PG16 (GN/YE) to the speed control actuator. When the brake pedal is applied, the voltage signal is removed from the speed control actuator and the speed control is deactivated.
A clutch pedal position signal is sent to the speed control actuator through circuit 15S-PG17 (GN/BU). When the clutch pedal is applied, the speed control is deactivated.
The speed control actuator sends and receives signals to the speed control switch through circuits 8-PG13 (WH) and 9-PG13 (BN). The speed control switch receive voltage through circuit 15-PG13 (GN/YE).
Immediately (0.25 second) after the static test has passed, the speed control actuator will carry out a dynamic test automatically by actuating the throttle lever from 1 to 10 mm (0.04 to 0.39 inches) of travel from the idle position.
The speed control actuator receives a voltage signal through circuit 15S-PG17 (GN/YE) from the stoplamp switch when the brake pedal is applied and the clutch pedal (if equipped) is released.
Voltage is supplied to the speed control deactivator switch through circuit 15-PG6 (GN/YE). The speed control deactivator switch sends a voltage signal through circuit 15S-PG16 (GN/YE) to the speed control actuator. When the brake pedal is applied, the voltage signal is removed from the speed control actuator and the speed control is deactivated.
The speed control actuator receives a vehicle speed signal from the powertrain control module (PCM) through circuits 8-RE22 (WH/VT) and 8-PG18 (WH/BU).
