How did you read with PCMFlash after you have no comms with ECU?
Have comms, or not?

[teerak2uk]

Used pcmflash bench mode module #71 to read and gave checksum fault so wrote file back and it corrected checks and is now ok.

Apparently it was caused by a fault with TGFlash version 1.20 bug

Because of our mistake in version 1.120 update we had to cancel this update.
Mistake was in checksum calculation for protocols 003, 004, 008, 009.
If you are experiencing ECU not responding issue - you need to fix checksum via bench programming.
