Hi

I just tested it in the car and unfortunately having issues.

There is one fault U3000:49-D0 CMDTCs control module.

Any idea what could be causing that problem? Is there any way to solve this fault?

Thanks

Check drivers on board, look closely with microscope and check, any time burn a little hole in driver and this need to change.

I did not find any burn marks on the drivers.

I will look again. I guess if ever it's burnt it would require a driver which would be difficult to find and probably require a new board.

Anyone can possibly try to clear the original file again? maybe it was not cleared properly. the error U3000:49 was not present when i first scan the car before i worked on it.
