IMPORTANT
When reprogramming onboard, please always make sure the vehicle battery is fully
charged and in good working condition to avoid the operation failure caused by the
abnormal voltage below the proper operating voltage. Sometimes the failure can be
recovered, but the failed reprogramming can also cause a fault in the control module.
We recommend connecting an external battery maintainer to the vehicle to ensure a
steady voltage is maintained throughout programming. The required voltage differs
by the vehicle manufacturer. Consult vehicle manufacturer for correct voltage to be
maintained.
Occasionally a flash update procedure may not complete properly. Common causes of
flash errors include poor cable connections between the tablet, VCI, and vehicle, the
vehicle ignition is switched off before the flash procedure is complete, or low vehicle battery
voltage.
If the process quits, recheck all the cable connections to assure good communications
and initialize the flash procedure. The programming procedure will automatically repeat if
the previous operation does not succeed. Please use this feature with caution and it is not
recommended for non-professionals.
