EPB Safety
It may be dangerous to perform Electronic Parking Brake (EPB) system maintenance, so
before you begin the service work, please keep these 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 be required to be deactivated 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 Electronic Parking Brake system.
Battery Management System (BMS) Service
The BMS (Battery Management System) allows the scan tool to evaluate the battery
charge state, monitor the close-circuit current, register the battery replacement, and
activate the rest state of the vehicle.
NOTE
1. This function is not supported by all vehicles. The screens shown in this section are
examples.
2. The sub functions and actual test screens of the BMS may vary for different test
vehicles, please follow the on-screen instructions to make correct option selection.
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 the replacement aftermarket battery has the same specifications,
such as capacity and type, with 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.
