NOTE:

From structure week 201020- the battery monitoring sensor (BMS) is LIN-connected to Central electronic module (CEM) instead of to Engine control module (ECM) as before. (For D4164T the battery monitoring sensor is still connected to Engine control module (ECM).)

The battery monitoring module is fitted on the battery's negative terminal and its main function is to monitor battery status.
