Yes, changing the node Id and back also does the trick, and faster then changing the speed.

Thank you for the replies, at the moment the LDU is turning how it should and we have a relaible methode to acces the interface.

The resistance between CANH and CANL is 60 ohms and at the moment it is only the logic board and the esp module on the CAN circuit

Small update: When changing the speed from 250k to 500k, the error disappears and the interface works. However, when I start the interface at 500k, it does not work and the error remains. Is there a specific reason for this?

The resistance between CANL and CANH is 60 ohms, the grounds of the esp and the ground of the motor are connected. If I measure the voltage from the ground of the esp module and the CANL or CANH I get 2,3Vfor both. If I check the CAN lines with the oscilloscope I also get the same value of on bothe ...

It is connected via CAN.

Hello everyone,

I'm a student from UHasselt in Belgium and for my master thesis I'm converting an Opel Speedster With an internal combustion engine to an EV. I'm using an Tesla LDU and the logic board swap for this motor from the Openinverter store. After connecting the logic board and the esp I am ...
