Rear Body Control Module (RBCM) Removal/Installation

WARNING: This page is about a different car, the 2014 Mazda 3. 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.
The rear body control module (RBCM) stores personalization setting information. The stored information is not cleared even if the battery power is disconnected.
Because the personalization setting information stored in the rear body control module (RBCM) cannot be written to a new rear body control module (RBCM), if the rear body control module (RBCM) is replaced, the personalization setting information is at the initial setting. Therefore, before replacing the rear body control module (RBCM), verify the personalization setting information and reset the replaced rear body control module (RBCM) with the information.

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