WARNING: This page is about a different car, the 2008 Lexus LS 600hL. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When the front millimeter wave radar sensor is replaced with a new one, adjustment of the radar sensor beam axis must be performed (see REMOVAL ).

Country specification information for vehicle and front millimeter wave radar sensor match	A
Country specification information for vehicle and front millimeter wave radar sensor do not match (Japan*↔Europe, Japan↔North America)	B
Country specification information for vehicle and front millimeter wave radar sensor do not match (North America*↔Europe)	C

HINT:

The country specification information of the driving support ECU is decided by the combination meter Even if the vehicle and sensor country specification information match, if the country specification information for the vehicle and ECU/meter do not match, it is necessary to replace the ECU and meter.
When the country specification information (North America*→Europe) for the vehicle body and sensor do not match, the sensor's information can be overwritten by performing the sensor's axis adjustment.
