I'm sure Tony will correct if needed...

It's not just NefMoto, but the protocol itself. The act of a successful flash using it clears the error flag. I know this from threads here.  Pretty fundamental to know if you're doing OBD tuning I'd say!

Sorry. I agree, it is critical to know this stuff Smiley

So: more dumb questions: The protocol used by NON bootmode flashers?

I don't know 100%. take a peek at the NefMoto log to check or see if you can find the thread where Tony discussed this issue. Sorry, I'd check myself buy I'm on my phone and it's a ballache.

To clear the invalid checksum error code you have to flash using the VAG programming protocol and then successfully disconnect. In the KWP2000 message handler for the StopCommunication message, it handles clearing the invalid checksum error code when successful programming has occurred.

Boot mode allows you to flash the flash memory, but it doesn't do anything to the eeprom where the error codes are stored.

Thanks for the clarification, Tony. I need to add a note to the S4wiki to that effect.

Successful disconnect! That's the key then.  I reflashed a couple of times and it didn't clear the code, mustn't have disconnected buy cycled the ignition instead?

Once flashing completes, you need to click the disconnect button. The disconnection process is what clears the error code.

The next release of the NefMoto flasher has changes to auto disconnect when flashing completes.

The changes for the next release have been going and going and going. I have a stable release that just adds support for premium fast flashing, but I am still working on fixing a number of communication issues before officially releasing the next version.

Hello.

I have the same problem. I have flashed my friends car with my custom map. Car drove perfectly for five days and next morning he couldnt get it to start. we counted he had started the car 17 or 18 times before dtc came up.
i pulled of the code P0601- Internal Control Module - Memory Checksum error.

car had an unknown remap on it before that had rsa failure when cheched. also boost sensor and throtle sensor map where ff-ed and some other maps have been modified in an unusal way.
we agreed to make a whole new map from ori file from web. its a seat cupra 1.8t 180 2006 ecu 06A906032RP 371739.

map i have uploaded is attached - can someone verify checksum please?

car alows me to read/write but doest let me cleard DTC p0601.  I have read most of the threads on here regrading p0601 and im still not sure which route to go to solve it?

thank you for your help

So nobody is going to paste the output of me7sum? Just make us do the work? Or mention if the NLS script was used on it?
