For 1990-2009 cars

The electronic cruise control system is a speed control system that maintains a desired speed under normal driving conditions. However, steep grades up or down may cause variations in the selected speeds. The electronic cruise control system provides the following features:

• | Cruise

• | Coast

• | Resume speed

• | Accelerate

• | Decelerate

The cruise control system consists of the following main components:

• | The cruise control actuator (which contains the control module and the stepper motor)

• | The cruise control cable

• | The cruise control release switch

• | The lever mounted functional control switches

• | The EBTCM (which provides the vehicle speed input)

An electronic controller and an electric stepper motor in the actuator function to obtain the desired vehicle cruise operation. The controller monitors the vehicle speed and operates the stepper motor. The motor then moves a ribbon which is connected to the cruise control cable and the throttle linkage in order to maintain the desired cruise speed. The cruise control module contains a low speed limit which will prevent system engagement below a minimum speed of 40 km/h (25 mph). The functional control switches on the turn signal lever control the controller operation.

### Description

#### SET/ACCEL

The SET/ACCEL switch activates the cruise control system which will only activate if the vehicle speed is at or above 40 km/h (25 mph). This switch also serves to accelerate the vehicle once the system is engaged. If the switch is held in the ACCEL position for more than one second, the system goes into the acceleration mode. The button is held until the desired speed is reached. When the switch is released, the system will maintain the desired speed. The SET/ACCEL switch can also be used to tap up the vehicle speed. Each tap on the switch will increase the vehicle speed in 1.6 km/h (1.0 mph) increments.

#### RESUME/DECEL

The RESUME/DECEL switch allows the cruise control system to return to the last speed setting recorded since the vehicle was last put in PARK, such as after momentarily braking. All cruise control information is erased when the vehicle is put in PARK. This switch will only work after an initial speed has been set using the SET/ACCEL switch. Do not hold the RESUME/DECEL switch in the RESUME position. This switch also decelerates the vehicle with the system operating. Holding the switch in the DECEL position lowers the vehicle speed. When the switch is released, the system will maintain the new cruise speed. The switch can also be used to tap down the vehicle speed in the same manner as the SET/ACCEL speed taps up the vehicle speed.

#### OFF

The OFF switch, located on the turn signal lever, disengages the cruise control operation. The previous speed setting in the memory is then erased.
