PRE-COLLISION: PRE-COLLISION SYSTEM: C1A01: Driving Support ECU

DTC C1A01 - Driving Support ECU

DESCRIPTION

The driving support ECU uses the front millimeter wave radar sensor to detect obstacles in front of the vehicle.
Based on this information, the driving support ECU calculates the risk of a collision and operates the pre-collision system when it determines that the risk is high.
When DTC C1A01 is detected, the driving support ECU only detects the "Pre-Collision 2" DTC malfunctions.
