Hi. 2010 RSS parking sensors are not working. All errors have been cleared and it is known that one rear sensor needs to be replaced. All cameras work, but the sensors do not work. What do you recommend?

Front parking aid will be parking sensor. Put it in reverse with ignition on only preferably with someone sat in the car with foot on the brakes. Listen to the sensors they will click. You’ll find you’ve got a dud one. Cheap and easy enough to replace as I’ve done myself.

I know which sensor is broken but the question is why don't all the other sensors work?

if one is not working then the electrical circuit will not be complete so that could cause the others not to work

One Sensor will knock out front and rear

I wouldn't have believed that, but thanks for answering.

it's fine some people don't know
RRS are here to test us 😅😅
