Help Truck Wont Start - Flash messed up somehow?

[BlownAlaskan]

I changed a shift point the other night and then hit the flash cal button just like normal and it erased memory, started to write and then froze about 4 seconds in. After I waited for several minutes to be sure it had indeed froze, I went ahead and hit the stop button. Now the truck will not start and when I try to read or flash and gives the message:

pcm did not accept the bootloader, reason: efilive could not unlock pcm. Then it wants me to enter the unlock code.

What does this mean? Did I cook the pcm? Any way to fix it? I have never locked the pcm.

Best regards,

Ben,

If this was a cal only flash then you should always be able to recover.
'Worst case', this should not be needed, but pull the fuse for the PCM power for a minute or so then retry.
If the PCM is missing the calibrations then when you try to flash the program it should just give a message that the PCM is missing the calibrations and will be recovered.
If this does not work look in the folder -
\My Documents\EFILive\V7\Bug reports
for the last 'download' blx file that was created and Email it through to us.
either ross@efilive.com or support@efilive.com

Okay, that fixed it. Forgot about those fuses. Thanks Ross.

Ben,

The fuses should not need to be pulled to retry a failed flash, they should never be pulled on a full flash fail.
But sometimes these things happen and I can't explain them :roll: :oops:

Cheers,
