Model: Sprinter 2.9TD
Motor capacity: 2.9 TD
Diesel/Gasoline: diesel
Production year: 1998
ECU type and number: MSA 25.3 0281001643
Memories of ECU: 24C04
Description: Spare ECU Number 2: MSA 25.3

I bought two Julie light emulators to fit into two spare ECUs from Ebay with full Horsepower.
The original ECU with reduced 75 HP is working with Immo and cruisecontrol. (No modifications done to this.)

I equipped both spare ECUs with Julie. Using the Immo Off modifications*) to 24C02 Eprom did not work. Julies LED flash indicate no connection to CAN-Bus. The car does not start.
There is no separate Immobox in my car.

I need help to get Julie working with my car/ECU combination!

I searched for a separate Immobox as described in your manual, but I did not find a separate Box. My Mercedes Dealer told me, that there are versions of the car with a separate Box and without.

How should the LED response of the Julie LEDs should be, If the ECU is not in the car? I powered up the ECU on my workbench with +12V and Ground with buildin Julie and the modified Eprom. The result was a fast blinking. Is this normal?

I hope to make the next step to find the problem.

Hi.
Which ECU is the original ECU from the car? ECU with number 0 281 001 643 or 0 281 001 644?

Both ECUs are not from my car. I have three alltogether.
My original box is in the car.

I can give you the ECU number if you need it. It is a MSA 25.2.
I am not at home until sunday to fetch the complete numbers.
I do not have the Eprom content of my original box.

Did you receive and test both ECUs? Is the blinking behavior of Julie correct?

There is no CAN trace for the immobilizer in the ECUs you sent us. CAN is working properly. We are not able to do anything, because our emulator will work only when there is a CAN trace. CAN is not damaged, probably the ECUs program is damaged. That's why we're sending everything back to you.
