The passenger's side BSM light doesn't turn on even if there is a vehicle in the way. The driver's side has no issues so I'm hoping to clean/check the sensor. Would anyone happen to know exactly where the sensor is located? Is it on the rear bumper? Many thanks in advance!

 

The sensors are located behind the rear bumper. Did you turn on the system? Does the lights come on when you turn on the car (self check)?

 

I did turn the system on manually -- the driver's side light works as expected. The passenger's side light does come on when the car is started... will do some more investigating! Thank you for your help!

 

The I bet the LED in the mirror is out or fell down. Probably they would need to replace the whole thing.
