Problem:
I gave power to both sides of the FoxFlash ECU Programmer and it broke, now it is not communicating with the laptop, is it possible to fix it?
There is no visible damage on the board.
Solution:
Step 1
Check if computer identifies device
Connect Foxflash Tool via USB (do not open the program), add 12v power supply, and open windows device manager.
Check device is showing in USB list.
Feedback:
An additional driver is displayed in the list when USB to Serial Converter is connected
Step 2
Try a different USB Cable and Port and new 12v power supply as the power supply unit may be damaged as well.
Feedback:
lights are on when USB is connected LEDs are on there is no possibility to install USB drivers
Step 3.
Uninstall USB to serial converter device and delete driver, reinstall Foxflash usb driver and plug in device.
If that fails then 2 voltage regulators LM317T’s and 1 V8674120 would be initial tests, get somebody trained in PCB repairs to do these tests
Hope this helps!
