Rear Body Control Module (RBCM) Removal/Installation

WARNING: This page is about a different car, the 2017 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

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.

NOTE:

The rear body control module (RBCM) prior to replacement stores the vehicle specification information.
A new rear body control module (RBCM) does not store any vehicle specification information.
If the vehicle specification information from the rear body control module (RBCM) prior to replacement cannot be read, perform the configuration using As-Built data.

When replacing the rear body control module (RBCM), perform the configuration. (See REAR BODY CONTROL MODULE (RBCM) CONFIGURATION (USING READ/WRITE FUNCTION) .)
