Lane Departure Alert System

CRUISE CONTROL: LANE DEPARTURE ALERT SYSTEM: C1A0C: Object Recognition Camera Region Code Mismatch
C1A0C - Object Recognition Camera Region Code Mismatch

DESCRIPTION

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 the country specification information from the main body ECU (multiplex network body ECU). When the country specification information in the lane recognition camera sensor assembly and driving support ECU do not match, DTC C1A0C is stored.
