Hello, thank you for your question. The FSD was working fine until I took the car to a car wash. The radar became defective and the updates were stopping at 30%. I then purchased a replacement radar and the updates went through but the autonomous driving error message was still there. I need to do a manual calibration because I can’t currently take it to Tesla service center (where they would use toolbox) due to COVID border restrictions in my country. Do you have any recommendations on manual calibration ?How do you know you have a radar calibration issue? I get this error when a major camera is blocked by direct sunlight, dirt, bad weather, etc., or any set of circumstances where the autonomous driving does not feel it can do a good job.
Thanks a lot for your quick answer. I tried so many times this procedure for the old model but doesn’t work for me. I can’t align the horizontal position because it’s much different than the first version.Basic Calibration:
More details on how to do the Horizontal Calibration:
Horizontal Calibration
Unfortunately, to receive any feedback from the car about horizontal calibration, you need Tesla’s Toolbox software, which is not available to the general public. However, you can get close enough by hand to meet the tolerances for Autopilot.
Note: it can take up to 50 miles of driving for Autopilot to self-calibrate after a radar calibration. In such cases you will continue to see the DAFU message for some time even after the radar is properly adjusted.
- After performing vertical calibration, notice the other 3.5mm hex nut to the left of the radar. This nut is used for horizontal calibration.
- Using a combination of eyeballing and measuring the distance between the radar and radar frame at each corner, adjust the horizontal calibration nut until the radar appears horizontally centered.
- Turn on the car. Wait ten seconds. If you see a “Driver Assistance Features Unavailable” message, turn your car off and repeat step 2, ensuring it is off for at least two full minutes between tries. If the DAFU message just won’t go away, get as close as you can, and proceed to step 4.
- If you don’t receive the DAFU message, nice work! Take the car for a drive and verify that Autopilot works.
Gasket Removal (Recommended)
If your radar still has a beauty gasket around it, and you drive in subfreezing temperatures, it is recommended that you remove it. Instructions can be found here.
did you get this issue resolved? radar recalibrated?Yes The text is upside down but I can’t find a way to rotate it the reader is on one side only.
