5.5 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 done.
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, 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.
