Cruise Control System Description
2000 Saturn LW1 L4-2.2L VIN FSECTION Cruise Control System Description
The electronic cruise control is a speed control system which maintains a desired vehicle speed under normal driving conditions.
The cruise control system has the following capability:
^ To cruise/maintain speed
^ To coast
^ To resume speed
^ To accelerate
^ To tap-up and tap-down.
The cruise control system contains the following main components:
^ The PCM
^ The cruise control switches
^ The cruise control module
^ The cruise brake switch
^ The cruise clutch switch
^ The stoplamp switch
^ The cruise throttle cable
The cruise control system uses a cruise control module in order to control the desired vehicle cruise operation. The module consists of the following two important components:
^ An electronic controller
^ An electric stepper motor
The controller performs the following functions:
^ Monitors the vehicle speed
^ Operates the electronic stepper motor This motor moves the connecting strap and the cruise control cable, in response to the controller. The desired cruise speed will be maintained.
The cruise control module contains a low speed limit that will prevent system engagement below a minimum speed of 39 km/h (24 mph).
The functional control switches, located on the steering wheel control the operation of the controller.
A cruise brake switch and stoplamp switch disengage the cruise system by means of the brake pedal. The switch is mounted on the brake pedal bracket assembly.
The cruise clutch switch, located on the clutch pedal bracket, will also disengage the system.
When the brake/clutch pedal is depressed, the following actions occur:
^ The cruise control system electronically disengages.
^ The throttle returns to the idle position.
