DESCRIPTION
The driving support ECU uses the front millimeter wave radar sensor, rear 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-crash control operation signals.
When the driving support ECU receives information that there is a malfunction in the driver monitor ECU, DTC C1A30 is output.
