been trying to read the ECU in a 2000 1.8T GTI. but i keep getting "ECU reports that security access is not supported" i tried 2 different ECU's and no luck. the car runs fine and there is no aftermarket programming done to it. i could not access the ECU at all unless i pulled the cluster fuse. i pulled the ECU and the chip inside is a 29F400BB. am i doing something wrong or will this tool not work with this ECU?
here's a log from NEFMOTO.
here's the ECU info.

It's failing because of this:
"Start diagnostic session failed, ECU reports conditions not correct or sequence error"
Can you go to the file menu in the flashing software, and then open the log file location. Then please post that log file so we can see the detailed information of what may have gone wrong.

That's enough info.
hmmm... preconditions met, but can't start programming session...
The ECU is installed in the car, and the engine was not running correct?

no, i have them out on the bench with a harness i made. im using a computer power supply to to power the ECU and all that fun jazz.

My best guess at this point, is that the ECU wants to be installed in the car talking to the immobilizer, even though it says all of the programming preconditions have been met.

well i am working on adding the connectors in for an instrument cluster so that it has access to it and i can recode my cluster to the ECU im working with. seems like the only option i have to be able to access an ECU without a car.

If you can disable the immobilizer coding in the ECU, then that should also allow you to connect.

Hey Tony, I've been lurking here a bit, but finally posting. I am trying to clone a replacement ECU for a family members A4. I need to do this on the bench as they live a ways from me. Could you elaborate on how to disable this immo coding on the bench so that I can utilize your software to complete this. I'll also open this up to anyone else reading, if you can help me get squared away I would appreciate it. As of now I am thinking I need to purchase some sort of SO8 test clip to read out and modify an eprom on the bottom of the ECU. Is there a better method? Thanks in advance... Sean |

If you're doing a true clone of an ECU there is no need to disable the immobilizer.
Either way, cloning the ecu or disabling the immobilizer does require you to be able to read/write the serial eeprom. I use a UPA-USB with an SOIC-8 clip to read/write them in circuit.
btw 337 FTW !

Thanks kls, So all I really need to do is copy the contents of the original serial eeprom off the back off the ecu and flash that onto the replacement ECU. This is going to transfer all of the immo settings, VIN # etc correct? Edit - and to keep this relevant to the original thread, this would be where the immo could be disabled if needed? Sean |

Yes, if you use an eeprom reader/writer and copy the entire serial eeprom it will preserve all settings.
To disable the IMMO change the $01 to $02 at addresses $12 and $22.
Then correct the checksums at addresses $1E and $2E by subtracting one from each.
I have verified this to work on both ME7.1.1 and ME7.5

From what I have seen, if the ECU has an immobilizer, then you can only flash it in car where it can talk to the immobilizer. To allow flashing on the bench, the immobilizer must be disabled. This of course only applies to flashing with the KWP1281 or KWP2000 protocols, because flashing with bootmode bypasses everything. |
