Cruise Control for 2GR–FE
System Outline
The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makes
it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal.
1. Set Control
When the –SET switch is turned from ON to OFF during driving with the main switch ON, the vehicle speed at that time is
registered and the vehicle is controlled at that constant speed.
2. Coast Control
When the –SET switch is kept ON during driving with the cruise control, the cruise control required opening gets zero to
reduce the vehicle speed. If the SET/COAST switch is turned OFF, the vehicle speed at that time is registered and the
vehicle is controlled at the constant speed.
3. Tap Up Control
Whenever +RES switch is tapped ON instantaneously (For approximately 0.5 sec.), the registered vehicle speed increases
by about 1.6 km/h.
4. Tap Down Control
Whenever the –SET switch is tapped ON instantaneously (For approximately 0.5 sec.), the registered vehicle speed
decreased by about 1.6 km/h.
5. Accel Control
When +RES switch kept ON during driving with the cruise control, the engine control module controls the throttle valve to
accelerate the vehicle.
It also registers the vehicle speed when +RES switch is turned OFF and controls the vehicle at the constant speed.
6. Manual Cancel Mechanism
If any of the following signals is input during cruise control travelling, the cruise control is cancelled.
∗ The stop lamp SW is turned on.
∗ The CANCEL SW is turned on.
∗ The ON–OFF SW is turned off.
∗ Gear is shifted from D position to other positions than D.
7. Auto Cancel Function
If any of the following conditions is encountered, the cruise control is automatically cancelled.
∗ The stop light SW wiring is faulty or short–circuited.
∗ The vehicle speed signal is faulty.
∗ The electronically controlled throttle malfunctions.
8. Other Cancel Function
If any operate VSC system the cruise control is cancelled.
9. Overdrive Control Function
The overdrive control may be cancelled if the vehicle travels on the slope during cruise control travelling. After the overdrive
control has been cancelled, when climbing hill is judged to finish from throttle opening information, the vehicle returns to the
overdrive control mode again after the overdrive return timer is completed.
