The console (2) will now display information as the flash process progresses.
As the vehicle enters the proper flash state all CAN BUS traffic will stop and modules will shut down.
You may see some communication errors regarding certain modules displayed while gaining security access, this is normal.
Once access is granted the flashing procedure will commence and a completion percentage will update in real time.
As the flash is wrapping up you may again see some communication issues with certain modules, again this is normal.
When the flash routine is finalizing modules will come back online and alarms may once again sound. This is normal.
When prompted cycle the key off and on and click ok.
The flash is now successful and you’re all set! See special precautions at the end of this section for other important data.
Warning |
---|
It’s possible for the fuel gauge, TPMS, steering wheel, or other systems to show errors after the flash process. There is nothing to be alarmed about. You can start by performing a “Clear Faults” action via M-Tuner. Driving around the car for a few miles and insuring full lock to lock with the steering wheel can help clear these faults as well. They just need some time to reset and relearn. |
ECU Recovery
In the very rare instance a flash were to fail due to low battery voltage, turning the car off during a flash, etc, we have built a recovery mode that can flash your ECU even if the flash was inhibited while in progress.
Now, if for any reason discussed above the flash fails you can now simply flash your M-Tuner(F) file to the vehicle and it will recover and you’ll be on your way.
