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
