Pre-Collision System (w/ Driver Monitor Camera)

PRE-COLLISION: PRE-COLLISION SYSTEM (w/ Driver Monitor Camera): C1A01: Driving Support ECU
C1A01 - Driving Support ECU

DESCRIPTION

The driving support ECU uses the front millimeter wave radar sensor, object recognition camera sensor and driver monitor camera to detect obstacles in front of the vehicle and the direction that the driver's head is facing.

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.
