Pre-Collision System

PRE-COLLISION: PRE-COLLISION SYSTEM: C1A0C: Object Recognition Camera Region Code Mismatch
C1A0C - Object Recognition Camera Region Code Mismatch

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 lane recognition camera sensor assembly is replaced with a new one, it acquires the country specification information from the driving support ECU. Also, when the driving support ECU is replaced with a new one, it receives country specification information from the main body ECU. When country specification information in the sensor and driving support ECU do not match, DTC C1A0C is output.
