Then I’ll try it again at 360 V. If it’s already defective, it doesn’t matter.

Every used SDU has already been run at 400 V, so the 50 V test mentioned in the forum is explicitly intended only as a gentle trial, while the unit is stationary at low speed and should not be considered a test drive ...

Yes, it could be possible. The diode test is fine, though. It was just a short ride on a flat street. The power was turned off after it stopped — but who knows?

What I have done so far:
udcmin 0
udcsw 0
Voltage 50 V
Motor rotates
Then motor installed in the car, drive shafts and wheels mounted, car lifted on a jack.
udcmin 0
udcsw 0
Voltage 83 V
Motor rotates with the wheels
Then motor in the car, drive shafts and wheels mounted, car lifted on a ...

I managed the download. Here are my values:

udcnom = 300V

How can I create this .json-file?

Thanks, I found it. It’ll be some work, but I hope the engine runs again.

Hello Johannes, thanks for the tip. Unfortunately I didn’t fully understand it and couldn’t find any information about it. Do I need to take the SDU apart and remove a jumper on the board?

Thank you very much for the help. I performed the diode test. The positive‑negative terminals show from 2V to zero, and with reversed polarity I get 0.7 V. All three phases show from 2V to zero, and with reversed polarity I get 0.35 V.
I calibrated the throttle – minimum value 414 and maximum 2356 ...

I tested my SDU while the car was stationary and the motor spun up successfully. After that I drove about 50 meters and everything was fine. Later I tried to drive again, but nothing happened—no throttle response.
I had set the parameters 45 udcmin and 72 udcsw to zero.
An E46 throttle pedal is ...
