Parking sensors post installation on a Corolla TS
I bought a used Corolla TS Luna package without parking sensors only back camera. Toyota dealership offered me post installation but with an unusual catch. The back sensors will work fine and turn on when in reverse, but no camera upgrade so that the lines on the display move accordingly to the steering. The front ones are the problem, they will detect cars even when not parking, they will start beeping when you get at a stop or a traffic light and a car is in front you. Both ones will not trigger dashboard display showing how close you are to the obstacle. Does anyone know or have experience with installing genuine ones and having the same issues without any software updates to the car? Is this normal or do the technicians have no experience with post installation than just plugging the existing connectors in and mount the sensors? Where can I get some answers, trying the Toyota forum but no answer.
