Mazda CX-5 Service & Repair Manual: Front Body Control Module (Fbcm) Removal/Installation
CAUTION:
-
If configuration is not performed when the front body control module (FBCM) is replaced with a new one, the vehicle specification information is not stored in the front body control module (FBCM) and the system will not operate normally.
-
When performing configuration, it is necessary to read the vehicle specification information from the front body control module (FBCM) before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the front body control module (FBCM). The vehicle specification information is temporarily stored in the M-MDS.
NOTE:
-
The front body control module (FBCM) prior to replacement stores the vehicle specification information.
-
A new front body control module (FBCM) does not store any vehicle specification information.
-
If the vehicle specification information from the front body control module (FBCM) prior to replacement cannot be read, perform the configuration using As-Built data.
