C1A20 - Object Recognition ECU
DESCRIPTION
The driving support ECU uses the millimeter wave radar sensor assembly, lane recognition camera sensor assembly and driver monitor camera* 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 lane recognition camera sensor assembly, DTC C1A20 is stored.
