DTC U3000:41-48 General Checksum Error

Post by Storkpkp »

After flashing my firmware on my APIM I am getting this DTC. I don't see any adverse affects, but I was wondering if anyone knew more about this or had seen it.

Thanks

I just did that. It was seeing it as SYNC 1, so I had to write some values to get it to recalculate checksum. Then it allowed it to see it right. I then reloaded from my saved values. Is that the part where I am messing up. Do you have to manually write them?

if you have changed the original as built due to having modded the car then you dont load as built , you have load up the modded as built that you should have saved when you made the mods .
i am the same as you just a forscan user still learning .
The search function is there for a reason use it.
no you can no longer pm me with your 1 or 0 posts so dont try.

I have rewritten without modifies as-built, force restarted my module but error renaming! I have old style IPC version can it be that?

Its a fimrware checksum error, this means you have a corrupt module firmware. Make sure you have a battery charger plugged in and "force" program the module to the same version as it currently is. Then the DTC should clear.
