Hello Everyone,
I just received my ECU back from Tim and I am not able to enter the Diagnostic mode to reset the codes.
If I press & hold the two buttons and turn on the ignition, I see the Er-4 (Error 4) on the screen and blinking temperature gauge.
I don't have the immobilizer connector under the right scoop, so it's not that.
Did anyone face the same issue?
