Note

•  The vehicle control module (V/C-module) prior to replacement stores the vehicle specification information.

•  The new vehicle control module (V/C-module) does not store any vehicle specification information.

•  When the ignition is switched ON after the vehicle control module (V/C-module) is replaced, the vehicle control module (V/C-module) reads the vehicle specification information sent via CAN transmission from the instrument cluster, and stores the vehicle specification information.

•  The automatic configuration function is only performed when the vehicle control module (V/C-module) is newly replaced.
