Select Function menu and press Y button.
Important: To complete the brake fluid change process, make
sure vehicle battery is fully charged and is in good condition. The
brake tool keeps detecting battery voltage during the whole
process. Once the voltage is too low to support the operation, a
“STOP: Voltage at control unit SBC xx.xV” message indicating
battery low comes up as below:
If the voltage stays at a low level, the device is not able to proceed
with the service work. So stop the service by holding N button for
at least 1 second, and an “Operation failed!” message comes up.
7) Follow onscreen instructions to complete the first phase of
operation:
