Do you have a code for yaw rate undone ?

Calibration

Enter Dealer Mode (Calibration) and clear the memorized steering sensor zero point, yaw rate and acceleration sensor zero point and system information, and then perform yaw rate and acceleration sensor zero point learning and system information memorization.

When I look on live data says yaw rate undone

I will take screen shots will do in 20 mins

Open TS and run a health check, what codes do you have

have you tried a zero point with the autel

[Abid ABS]

I tried exactly that both with techstream and autel . Just don't seem to work when looking at live data I can see speed on each wheel sensor.  But when I look at live data stationer says out of controlling to everything... what I've read says I shoukd drive it at 12 mph with brake switch off u heard of that ?

Yes, clear the C052f14 take it for a drive (do not have the scan tool plugged in)

[Abid ABS]

Ok just to let u no the code never clears its instantly comes back 

[flash22]

Used or new ABS pump ?
