AUTO-CRUISE CONTROL SYSTEM <4G69-Vehicles with auto-cruise control system>
By using the auto-cruise control, the driver can drive at preferred speeds in a range of approximately 40 to 200 km/h without depressing the accelerator pedal.
For this auto-cruise control system, in conjunction with the electronic throttle valve control system, the engine-A/T-ECU electronically controls the throttle valve.

COMPONENTS AND FUNCTIONS
Component
Function
Accelerator pedal position sensor
Informs the engine-A/T-ECU of the accelerator pedal depression.
Auto-cruise control indicator lamp
It is included in the combination meter and illuminates when the auto-cruise control "MAIN" switch is "ON" position.
Auto-cruise control switch
"MAIN" switch
Switch for cruise control power.
"SET/COAST" switch
Vehicle speed is set with the "SET/COAST" switch and "RESUME/ACCELERATING" switch.
"RESUME/ ACCELERATING" switch
"CANCEL" switch
Cancels the cruise speed setting.
Cancel system
Stop lamp switch
Outputs a signal to cancel cruise control
Inhibitor switch
Diagnosis connector
If the MUT-II/III is connected, the diagnosis code and input check code from the engine-A/T-ECU can be read.
Engine-A/T-ECU
  • Judges how the cruise control is operating by using input signals from the auto-cruise control system and the cancel system, and sends the throttle valve opening angle signal to the throttle actuator control motor by using the accelerator pedal position sensor signal.
  • The diagnosis code and input check code are sent to the diagnosis connector.
  • When the "MAIN" switch "ON" signal is entered, a signal is sent to illuminate the auto-cruise control indicator lamp.
Throttle valve control servo
The throttle valve opens and closes in response to the throttle angle control signal from the engine-A/T-ECU.
Throttle position sensor
Informs the engine-A/T-ECU of the throttle valve opening angle.
