Ok so has anyone replaced their rear sonar sensor? I am also noticing that when I am backing up to a wall in a parking garage sometimes the proximity beep sounds and sometimes it doesn't. Bad sensor maybe? Based on the system description at the site page below:

My system isn't even close to working correctly. I get an occasional single beep.

If you're sure it has sonar (warts on the rear bumper) then you should probably get it scanned for codes, some MY's will warn you in the cluster if it's inop but some won't. Most stuff from '13 up has MOD (Moving Object Detection) even if it doesn't have sonar. MOD will give you a single beep, but it won't go off for a wall or garbage can, only something that's moving behind you like a car or pedestrian. The bumper warts mean a car has sonar, no warts means it only has MOD.

VStar650CL. No warts. I just did a walk and there aren't any. This 2017 SV does have RTCA and blind spot warning alert but no driver assist auto braking or anything like that. It does have the look around cameras system with one under each side mirror and one in the back liftgate. I'm not sure what kind of sensors are required for RTCA and BSW but I don't see any external sensors other than the cameras. I found a liftgate sensor on eBay:

I'm assuming that is the sensor responsible for triggering the liftgate but I'm not sure what "brain" it connects to. Any idea which FSM chapter covers these sensors?

Topic split to create it's on thread. Please try to avoid thread hijacking.

No, the liftgate kick sensor is a third animal altogether, it's embedded in the rear under-cover and has its own brain. RCTA and BSW primarily use the side radars underneath your rear fenders coupled with the side and rear cameras, while MOD is purely optical using the cams alone. Neither system uses sonar. The beep you're hearing occasionally is probably MOD.

My questions were in a thread that was regarding the rear liftgate. It was an old thread I thought was relevant to my problem which is my rear liftgate is not operating. I didn't think I was hijacking anything and frankly don't like being accused of such. Why don't you just clear my registration and I'll find another forum which is not so pissy. Have nice day moderator.
