C1A30 - Driver Monitor ECU

DESCRIPTION

The driving support ECU uses the millimeter wave radar sensor assembly, driver monitor camera and lane recognition camera sensor assembly to detect obstacles in front of 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 driver monitor ECU, DTC C1A30 is stored.
