Man TGL 12.250 - error 3257, 3650, 3209, 3519, 3207, 3522, 3002

Hello
I'm having trouble with bugs in Man TGL 12.250. Errors 3257, 3650, 3209, 3519, 3207, 3522, 3002, probably several of them are from one fault, but I don't know which one exactly.

Mistake:
3257 - applies to EBS, pressure control module, rear axle right; impulse ring error
3209 - pressure regulation module, rear axle on the left; no valid definition
3207- pressure regulation module, rear axle on the left; impulse ring error, left wheel sensor
3002 - damaged control device; unknown uC interrupt, timeout during data exchange, uC active or passive
3519 - Wheel rotation sensor, error during the last connection cycle
3522 - diagnostic mode active
3650 - CAN semi-trailer interface, partial or complete failure of the tractor-semi-trailer interface.
All errors are related to EBS.

Thanks a lot. What can I do with it or replace it?

Such a flood of errors concerning one system is probably not a coincidence. What has been done so far?

Discs and pads replaced.

Check:
- EBS sensors for resistance and damage on both sides, right / left
- wires of these sensors for damage, abrasions, breaks
- impulse rings in both hubs, whether they are not damaged, crooked, corroded
- there are no play in the hubs, because maybe the bearings are ending and thus the gap between the sensor and the impulse wheel has increased
- EBS socket and cable semi-trailer - tractor for abrasions and corrosion, if the EBS socket or plug is green, it must be repaired / replaced.

That's it for the beginning. Oh, and check the brake pad wear sensors and their wiring.

Thank you very much, I'll check it tomorrow and let you know.

By my understanding, when removing or installing the brake disc, you damaged the pulse generator ring or you did not clean it with a wire brush. If rust gets into the pulser wheel gap, the sensor will read it as an error or even if you accidentally treated the ring with a hammer, the effect will be the same.

I have a problem with the EBS 3522 error and I do not know where to look for the cause.

I know, I read it before and my point is that I don't know where to look for the cause of this error.

Plug in your computer, preferably MAN Cats, and you'll know where the cause is. The scope of this error can be extensive.

To my eye, the controller under the pedal (burnt?). Were there any adventures with the so-called boot device? Any visible symptoms? Check that the brake lights do not go out sometimes.
