Pre-Collision System

PRE-COLLISION: PRE-COLLISION SYSTEM: C1A10: Front Radar Sensor
C1A10 - Front Radar Sensor

DESCRIPTION

The driving support ECU uses the front millimeter wave radar sensor, driver monitor camera and object recognition camera to detect obstacles in front of and behind the vehicle, and detect the direction that the driver's head is facing. Based on this information, the driving support ECU sends pre-collision control operation signals.

When the driving support ECU receives information that there is a malfunction in the front millimeter wave radar sensor, DTC C1A10 is output.
