Rear Body Control Module (RBCM) Removal/Installation

CAUTION:

If configuration is not performed when the rear body control module (RBCM) is replaced with a new one, the vehicle specification information is not stored in the rear body control module (RBCM) and the system will not operate normally.
When performing configuration, it is necessary to read the vehicle specification information from the rear body control module (RBCM) before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the rear body control module (RBCM). The vehicle specification information is temporarily stored in the M-MDS.
