Re-flash Errors

IMPORATANT

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 programming . The required voltage differs by 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, VCMI, and vehicle, the

vehicle ignition being 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.
