Steering wheel out of calibration

[KarolGT]

Another question regarding my 4WAS problems.

What could be causing my steering wheel to become out of calibration?

I've calibrated it three times now, and after a few days, the steering wheel is turned about 5-10 degrees to the left to drive straight.
I did a Consult3 calibration, and it was fine for a few days, but now it's the same, but to the right.

No error codes.

Thanks in advance

Sounds like maybe your Steering Angle Sensor is losing its brains. The RAS unit and ABS both get the front wheel angle via CAN from the SAS in the steering column. The SAS calibrates through ABS work support but it has its own calibration memory. I've seen numerous examples on Nissans where an SAS seems to calibrate okay but then the memory corrupts. Since the SAS and ABS are unaware that the SAS is lying, all kinds of weird symptoms can occur, sometimes with no codes at all.

Thanks. So should I replace the Steering Angle Sensor in the steering column or other ECU?

btw. this is my orignal problem with 4WAS 4was-working-continuously-t635237.html

The SAS.
