Hello,
Your file virgin OK

[workshop bot]

Nicely done. It worked perfectly. Was able to write key tracks and coding. Unfortunately, I think the donor ME is bad. Setting codes for terminal 87 low voltage. Verified power and grounds to ME again. All good. Do you think I could use the same virgin file on the 2nd donor ME?

My first donor ME is no good. I have a 2nd I need virgin please.

It is running. Blown capacitor in original ME. Had to replace front SAM also due to low voltage to injectors, coils, cam adjusters, etc. All started with a dead battery before it came to workshop.
