System description

  1. Cruise control system

This system is controlled by the ecm, and is activated by the throttle position sensor and motor. The ecm controls the following functions: on-off, set / coast, resume / accel, cancel, vehicle speed operation, motor output control, and overdrive control.

  1. Limit control

  1. Low speed limit the lowest possible limit of the speed setting range is set at approximately 40 km/h (25 mph). The cruise control system cannot be set when the driving vehicle speed is below the low speed limit.

    Cruise control operation will be automatically canceled when the vehicle speed decreases below the low speed limit 40 km/h (25 mph) while the cruise control is in operation.

  2. High speed limit the highest possible limit of the speed setting range is set at approximately 200 km/h (125 mph). The cruise control system cannot be set when the driving vehicle speed is over the high speed limit.

    Also, +/res cannot be used to increase speed beyond the high speed limit.

  1. Operation of cruise control

The cruise control switch operates 7 functions: set, coast, tap-down, resume, acceleration (accel), tap-up, and cancel. The set, tap-down and coast functions, and the resume, tap-up and accel functions are operated with the same switch.

The cruise control switch is an automatic return type switch which turns on only when pressed in each arrow direction and turns off when released.

  1. Set control.

    vehicle speed is stored and constant speed control is maintained when pushing the switch to -/set while driving with the cruise control switch on (the cruise main indicator light is illuminated), and the vehicle speed is within the set speed range (between the low and high speed limits).

  2. Coast control

The ecm changes the cruise control demanding throttle opening angle to 0Рand decelerates the vehicle when -/set on the cruise control switch is pressed and held while the cruise control system is operating. When the cruise control switch is released from -/set, the vehicle speed is stored and constant speed control is maintained.

Hint:

  1. Tap-down control

When tapping down the cruise control switch to -/ set (for approximately 0.5 Seconds) while the cruise control system is in operation, the stored vehicle speed decreases each time by approximately 1.6 Km/h (1.0 Mph). When the cruise control switch is released from -/set and the difference between the driving and stored vehicle speed is less than 5 km/h (3 mph), the vehicle speed is stored and constant speed control is maintained.

  1. Accel control

The throttle valve motor of the throttle position sensor and motor is instructed by the ecm to open the throttle valve when +/res on the cruise control switch is pressed and held while the cruise control system is operating. When the cruise control switch is released from +/res, the vehicle speed is stored and constant speed is maintained.

  1. Tap-up control

When tapping up the cruise control switch to +/res (for approximately 0.5 Seconds) while the cruise control system is in operation, the stored vehicle speed increases each time by approximately 1.6 Km/h (1.0 Mph). However, when the difference between the driving and the stored vehicle speed is more than 5 km/h (approximately 3.1 Mph), the stored vehicle speed will not be changed.

  1. Resume control

If the cruise control operation was canceled with the stop light switch or the cancel switch, and if driving speed is within the set speed range, setting the cruise control switch to +/res restores the vehicle speed memorized at the time of cancellation, and constant speed is maintained.

  1. Manual cancel control

Performing any of the following cancels the cruise control system (the stored vehicle speed in the ecm is maintained).

  1. Auto cancel (fail-safe)

This system has an automatic cancellation function (failsafe) (see page cc-17).
