Automatic check failed

With my hand, I see that one sensor doesn't work as parking sensor.

With the laser tester, I've hidden one by one the sensor with à piece of paper.

With the laser tester, I've hidden one by one the sensor with à piece of paper.- Paper does not completely block Infrared photons, some can still pass through & some will scatter for the other sensor to receive & will cause alert. The AL-P sensors are very,very sensitive to receive a small amount of IR signal from the Tester.

1. Did you label the cables like I asked you to do ?
Just as you posted before when you started this Thread, what were the results you got when you looked at the ALP report like in your Post #1 ?
