Attach battery maintainer to vehicle battery to ensure a steady voltage is maintained
throughout programming. Voltage requirements differ by vehicle manufacturer. Consult
vehicle manufacturer recommendations prior to programming a module.
Do not quit the application during a module programming as the process may fail and
may also result in permanent damage to the module.
Typical reprogramming operations require you to input and validate the VIN number first.
Tap the input box and enter the correct number. The programming interface then appears.

Sample Reprogramming Operation Screen
The main section of the reprogramming interface offers information about the hardware,
the current software version and the newest software versions to be programmed into the
control units.
A series of on-screen operational instructions will display to guide you through the
programming procedure.
Carefully read the on-screen information and follow the instructions to execute the
programming procedure.

IMPORTANT
When reprogramming onboard, always make sure the vehicle battery is fully charged and in
good working condition. During reprogramming, the operation may fail if voltage falls below
the proper operation voltage. Sometimes a failed operation can be recovered, but the failed
reprogramming can also ruin the control module. We recommend connecting an external
battery maintainer to the vehicle to ensure a steady voltage is maintained throughout
