BMS

The BMS (Battery Management System) allows the scan tool to evaluate
the battery charge state, monitor the close-circuit current, register the battery
replacement, activate the rest state of the vehicle, and charge the battery
via the diagnostic socket.
NOTE
This function is not supported by all vehicles. The screens shown in this
chapter are examples; actual test screens may vary for each vehicle being
tested. Observe the menu titles and onscreen instructions to make correct
option selection.

General Battery Information

The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed
Glass Mat) battery. Lead acid battery contains liquid sulphuric acid and can
spill when overturned. AGM battery (known as VRLA battery, valve
regulated lead acid) also contains sulphuric acid, but the acid is contained
in glass mats between terminal plates.
It is recommended that a replacement aftermarket battery has the same
specifications, such as capacity and type, of the battery used in the vehicle.
If the original battery is replaced with a different type of battery (e.g. a lead-
acid battery is replaced with an AGM battery) or a battery with a different
capacity (mAh), the vehicle may require reprogramming the new battery type
in addition to performing the battery reset. Consult the vehicle manual for
additional vehicle-specific information.
NOTE
Reprogramming is not supported by the scan tool currently.

Battery Operation

The Battery function allows you to evaluate the state of the battery charging
and register the battery replacement.
Take BMW as an example.
