This circuit provides power to operate the distance control ECU.

Using the intelligent tester, read the Data List ().

The distance control ECU sends the vehicle speed and estimated curve information to the millimeter wave radar sensor. The millimeter wave radar sensor sends information about whether another vehicle is present in front of the vehicle, the distance between the vehicles, relative speed, etc. to the distance control ECU. The distance control ECU sends this information to the ECM and performs control of cruise control.

The ECM sends the cruise control main switch signal, vehicle speed signal, etc. to the distance control ECU. The distance control ECU sends the acceleration signal, deceleration request signal, etc. to the ECM. The ECM controls cruise control according to these signals.

The distance control ECU sends general vehicle control information, such as vehicle speed, steering angle, etc., to the millimeter wave radar sensor. The millimeter wave radar sensor sends information about whether another vehicle is present in front of the vehicle, the distance between the vehicles, relative speed, etc. to the distance control ECU. The distance control ECU sends this information to the ECM and performs control of cruise control.

The ECM sends the cruise control main switch signal, vehicle speed signal, etc. to the distance control ECU. The distance control ECU sends the acceleration signal, deceleration request signal, etc. to the ECM. The ECM controls cruise control according to these signals.

This DTC may also be stored when there is a vehicle stability control system malfunction.

Using the intelligent tester, perform the Active Test ().

This DTC is stored when there is a problem with the millimeter wave radar sensor beam axis adjustment.

The millimeter wave radar sensor emits radar waves towards an object in front and measures the distance and direction of the object by receiving the wave reflections. Based on the reflections, the sensor calculates the difference in speed between your own vehicle and an object in front. This data is transmitted to the distance control ECU.
