How to disable RAB & Rear beeping

I recently had a eco hitch installed and am very happy with the hitch. Thanks to everyone here that recommended the eco hitch. Now that I have a hitch I have been using my bicycle rack. Unfortunately, when the 2018 OB limited is put into reverse, the RAB has activated 2 times. It stops the car very abruptly with a loud noise. In addition, it beeps. If I leave it in reverse but do not back up after about 15-20 seconds the RAB disables and I get a message on the dash board that says RAB disabled and P disabled. Can someone explain how they handle bike racks with this feature in the OB. Thanks in advance

When put in reverse, look to the lower right corner of the infotainment screen. There should be a digital button that you can press to turn off the beep. As far as I know, you have to do this everytime when you uave your hitch loaded.

Actually, you have to do it every time you shift into reverse. I believe others here have found a longer lasting solution.

I just checked.

Once disabled on my 2017 3.6 it stays off so long as the car is running.

I've got a 2018 2.5i with the Ecohitch installed and a bike rack mounted. When the rack is free of bikes and folded up, I start the car and put it in reverse, and I get the beeping, but the RAB is disabled without me having to do anything. I just got the rack set up, so I haven't actually tested it with bikes on it, but it seems strange that RAB is disabled automatically.

Not my 2018. If I shift out of reverse and go right back into reverse, RAB is re-enabled.

Same for me. If anyone knows a more permanent or longer lasting solution, please chime in

You could unplug the sensors.

If you want the able to switch it on and off you could build a switch that interrupts the sensors circuit and wire to the dash.

It's a single two wire plug for all the sensors on the rear bumper.

May need to review a wiring diagram for the ‘18. When we had our accident last month that busted a sensor we couldn’t turn off the beep and brakes except for the radio controls each time the car was put in reverse. The shop pulled the busted sensor out and it didn’t help. Seems if a sensor is faulty or unplugged it trips the system.

You people have it easy with just the bike rack . My rear auto brake locks every time I leave my driveway because it thinks I'm going to hit the road as our driveway has a slight incline. The only way to solve this is to trade the car in for one without RAB or push the button every time you put it in reverse.
