BMS RESET
The Battery Management System (BMS) 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.
This function enables you to perform a resetting operation on the monitoring unit of the vehicle battery, in which the original
low battery fault information will be cleared and battery matching will be performed.
Battery matching must be performed in the following cases:
⚫ The main battery is replaced. Battery matching must be performed to clear original low battery information and prevent
the related control module from detecting false information. If the related control module detects false information, it
will invalidate some electric auxiliary functions, such as automatic start & stop function, sunroof without one-key trigger
function or power window without automatic function.
⚫ Battery matching is performed to re-match the control module and motoring sensor to detect battery power usage more
accurately, which can avoid an error message displayed on the instrument cluster.
The operation guidelines of the BMS Reset function are shown as below:
1. Enter the BMS Reset menu and choose relevant models according to the vehicle being tested.
2. Turn on the ignition switch.
3. Press OK to continue the BMS function.
4. Enter battery capacity (within the given range) and press OK after the input.
