AUTO-CRUISE CONTROL SYSTEM <4G69-Vehicles with auto-cruise control system>

GENERAL INFORMATION
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. CONSTRUCTION DIAGRAM
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.
