My wife’s 2021 XLE had static yellow gridlines on the backup camera display. Since replacing her battery, however, the gridlines have disappeared, just leaving crossed blue lines in the display. She also had the diamond exclamation icon, which disappeared after I completed the steering calibration in the service menu. However, the yellow lines have yet to return despite repeating several times and driving for several days.
Any other suggestions to try? My searches keep bringing me back to videos of this same calibration process.
