C1A10 - Front Radar Sensor

DESCRIPTION

The driving support ECU uses the millimeter wave radar sensor assembly, lane recognition camera sensor assembly*1 and driver monitor camera*2 to detect obstacles in front of the vehicle and the direction that the driver 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 millimeter wave radar sensor assembly, DTC C1A10 is stored.
