Extracted TCM calibration file, edited it, flashed it back in, no problem. On the second write I received the error message
Eraser: x7F Negative Response Code
Whether I write or skip the ECM file first it gives the same error when trying to access the TCM, repeatedly.
The TCM uses the 8R29-7J104-AB Operating System
Vehicle is a 2008 FG XR6 Turbo sedan
Any assistance would be great, Thanks
Sasha.
