| Diagnosis and Testing Refer to Wiring Diagrams Section 310-03, for schematic and connector information. Principles of Operation There are two basic types of speed control: - Mechanical speed control
- Electronic speed control
MECHANICAL SPEED CONTROL The mechanical speed control system consists of one main component, the speed control actuator. Vehicles with a cable operated throttle body are equipped with this type of speed control system. The speed control actuator receives speed control commands from the steering wheel mounted speed control switches. The vehicle speed is monitored by the speed control actuator using the signal from the vehicle speed sensor (VSS). The vehicle speed is adjusted by means of a cable fitted to a cam, driven by a proportional electric motor housed in the speed control actuator. This cable is connected to the throttle body and operates the throttle linkage in the same way as a traditional accelerator cable. To prevent the vehicle engine working against the vehicle braking system, the brake pedal position (BPP) switch is used to monitor brake pedal movement. If the BPP switch is actuated, the speed control will disengage and normal engine operation will resume. To prevent uncontrolled engine acceleration with no transmission load, the clutch pedal position (CPP) switch is used to monitor clutch pedal movement. If the CPP switch is actuated, the speed control will disengage. The speed control system will not be enabled until the vehicles indicated road speed is 42 km/h (26.3 mph) or above. At this speed, the operation of the speed control ON switch will put the speed control system into standby mode. The instrument cluster speed control indicator lamp will not be illuminated. Standby mode will be maintained until the speed control OFF switch has been operated or the ignition key has been turned to position 0. Standby mode will be maintained if the vehicle indicated speed decreases below 42 km/h (26.3 mph). Speed control cruise function is disabled until the following criteria is met: - The vehicle indicated speed is above 42 km/h (26.3 mph)
- The speed control + switch is pressed
As long as these criteria are met, the instrument cluster speed control indicator lamp will illuminate to indicate the vehicle is under speed control. ELECTRONIC SPEED CONTROL The electronic speed control is restricted to vehicles with no accelerator cable. This type of speed control uses the PCM engine and transmission inputs and outputs to monitor, adjust and maintain the required vehicle speed. The PCM receives speed control commands from the steering wheel mounted speed control switches. Vehicle speed is monitored from the VSS input to the instrument cluster speedometer. Speed control is achieved by the direct input command from the PCM to the throttle body motor. The speed control system will not be enabled until the vehicles indicated road speed is 42 km/h (26.3 mph) or above. At this speed, the operation of the speed control ON switch will put the speed control system into standby mode. The instrument cluster speed control indicator lamp will not be illuminated. Standby mode will be maintained until the speed control OFF switch has been operated or the ignition key has been turned to position 0. Standby mode will be maintained if the vehicle indicated speed decreases below 42 km/h (26.3 mph). Speed control cruise function is disabled until the following criteria is met: - The vehicle indicated speed is above 42 km/h (26.3 mph)
- For vehicles with manual transaxle, third gear or above must been selected
- For vehicles with automatic transaxle, drive (D) must be selected
- The speed control + switch is pressed
As long as these criteria are met, the instrument cluster speed control indicator lamp will illuminate, indicating the vehicle is under speed control. To prevent the vehicle engine working against the vehicle braking system, the BPP switch is used to monitor brake pedal movement. If the BPP switch is actuated, the speed control will disengage and normal engine operation will resume. To prevent uncontrolled engine acceleration with no transmission load, the CPP switch is used to monitor clutch pedal movement. If the CPP switch is actuated, the speed control will disengage. Inspection and Verification - Verify the customer concern.
- Visually inspect for obvious signs of electrical or mechanical damage.
