Battery reset first.

I’ll replace the battery now. And try read faults again.
Thank you for your support.

Another malfunction is the buttons on the steering wheel do not work at all.

After replacing battery, l do clear fault code and try make parking brake calibration it’s give calibration error. After that I do diagnostic and still have faults.

You should never run a calibration on the handbrake.

it stretches the cable and locks up the ecu/drive unit.

handbrake off, adjust them manually through the disc hole till they lock then back off 3 flicks.

That’s it, set, also make sure your handbrake linings are good and not come adrift and the tin shield that the tops push off is not fractured or broken
