The electronic cruise control is a speed control system
that maintains a desired vehicle speed under normal driving conditions. Steep
grades or inclines may cause variation in the selected speeds.
The cruise control system has the capability to perform the following
functions:
The cruise control system contains the following main components:
| • | The cruise control switches |
| • | The cruise control module assembly |
| • | The cruise control brake switch |
The cruise control system uses a cruise control module assembly in order
to obtain the desired vehicle cruise operation. The module assembly consists
of the following 2 primary components:
| • | An electronic controller |
| • | An electric stepper motor |
The controller performs the following functions:
| • | Monitors the vehicle speed |
| • | Operates the electronic stepper motor |
The stepper motor moves the band and the cruise control cable in response
to the controller. The desired cruise speed is maintained.
The cruise control module assembly reserves a low speed limit that
prevents system engagement below a minimum speed of 40 km/h (25 mph).
The functional control switches on the steering wheel operate the controller.
A cruise control brake switch disengages the cruise system by means
of the brake pedal. The switch is mounted on the brake pedal bracket assembly.
When the brake pedal is depressed, the following actions occur:
| • | The cruise control system electronically disengages. |
| • | The throttle returns to the idle position. |
