COMPONENT PARTS AND FUNCTION OUTLINE

COMPONENT PARTS AND FUNCTION OUTLINE CHART

CRUISE CONTROL

Cruise control system is engaged by "ON/OFF" main switch located on right of steering wheel column. System
has the capability to cruise, coast, resume speed, and accelerate, and raise "tab-up" or lower "tab-down" set
speed.

It also has a safety interrupt, engaged upon depressing brake or shifting select lever.

ECM is a speed control system that maintains a required vehicle speed at normal driving conditions.

The main components of cruise control system are mode control switches, transaxle range switch, brake switch,
vehicle speed sensor, ECM and ETS motor that connect throttle body.

ECM contains a low speed limit which will prevent system engagement below a minimum speed of 40km/h
(25mph). The operation of the controller is controlled by mode control switches located on steering wheel.

Transaxle range switch and brake switch are provided to disengage the cruise control system. The switches are
on brake pedal bracket and transaxle. When the brake pedal is depressed or select lever shifted, the cruise
control system is electrically disengaged and the throttle is returned to the idle position.

Cruise main switch

Cruise control system is engaged by pressing "ON/OFF" push button. Releasing "ON/OFF" push button release
throttle, clears cruise memory speed, and puts vehicle in a non-cruise mode.

COAST/SET switch located on right of steering wheel column has two positions - "Normal" and "Depressed".
The set position - With COAST/SET switch depressed and then released the cruise speed will be set at the
speed the vehicle was going when COAST/SET switch was released. The coast position - With COAST/SET
switch fully depressed, driver can lower cruise speed. To decrease cruise speed, COAST/SET switch is held in,
disengaging cruise control system. When vehicle has slowed to required cruise speed, releasing COAST/SET
switch will re-engage speed at new selected speed.

The tab down - To lower vehicle speed, cruise must be engaged and operating. Tab down is done by quickly
pressing and releasing COAST/SET switch. Do not hold COAST/SET switch in depressed position.

Tab down is a function which will cause the cruise control's speed of vehicle to decrease by 1 MPH (1.6 km/h)

Resume/Accel switch

RES/ACCEL switch located on right of steering wheel column has two positions - "Normal" and "Depressed".

The resume position - With RES/ACCEL switch depressed and then release, this switch also returns cruise
control operation to last speed (Which is temporarily disengaged by Cancel switch or Brake pedal), setting
when momentarily operating RES/ACCEL switch by constant acceleration.

The accel position - With RES/ACCEL switch depressed and held in, disengaging cruise control system, when
vehicle has accelerated to required cruise speed, releasing RES/ACCEL switch will re-engage speed at new
selected speed.

The tab up - To increase vehicle speed, the cruise must be engaged and operating.

Tab up is done by quickly pressing and releasing RES/ACCEL switch less than 0.5 second. Do not hold
RES/ACCEL switch in depressed position. Tab up is a function in which cruise speed can be increased by 1
MPH (1.6 km/h).

Cancel switch

Cruise control system is temporarily disengaged by pressing "CANCEL" switch.

Cruise speed canceled by this switch will be recovered by RES/ACCEL switch
