EPB Safety
It can be dangerous to perform Electronic Parking Brake (EPB) system maintenance, so
before you begin the service work, please keep the following rules in mind:
Ensure that you are fully familiar with the braking system and its operation before
commencing any work.
The EPB control system may require deactivation before carrying out any
maintenance/diagnostic work on the brake system. This can be done from the tool
menu.
Only carry out maintenance work when the vehicle is stationary and on level ground.
Ensure that the EPB control system is reactivated after the maintenance work has
been completed.
NOTE
Autel accepts no responsibility for any accident or injury arising from the maintenance of
the EPB system.
5.3 Battery Management System (BMS) Service
The BMS (Battery Management System) allows the tool to evaluate the battery charge
state, monitor the closed-circuit current, register the battery replacement, and activate
the rest state of the vehicle.
NOTE
This function is not supported by all vehicles.
The sub functions and actual test screens of the BMS may vary by vehicle. Follow
the on-screen instructions to make correct selections.
The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed Glass Mat)
battery. Lead acid batteries contain liquid sulphuric acid and can spill when overturned.
AGM batteries (valve regulated lead acid, VRLA batteries) also contain sulphuric acid,
but the acid is contained in glass mats between terminal plates.
It is recommended that the replacement aftermarket battery has the same specifications,
such as capacity and type, as the original battery. 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.
