skydiverTX Love the 1UP, too bad it's been raining so I haven't been able to take the bike anywhere lately.

Short answer... No

The cable you are talking about is for attaching a brake controller to the controller harness connector under the dash.

The WK2 does not automatically detect a trailer via trailer signals or connections.

The sway control may notice a bit more sway to compensate for, and the transmission may notice a bit more load and adapt. But these are not a trailer attached indication.The TIPM may notice loads from trailer lights, but it doesn't notify any of the other computers.

There are vehicles that detect trailers, but that was left out of the WK2.

ColdCase Just to summarize

The lanesense uses cameras facing forward that detects lane markers. Your bikes should have no affect on lanesense.

The blind spot monitoring system uses RADARs to detect vehicles entering your blind spots. Your bikes should not be detected unless they are hanging way over the edge. Owners manual says: "If the trailer or other object (i.e., bicycle, sports equipment) extends beyond the side of your vehicle, this may result in random false detections on the trailer, and false chimes when the turn signal is used." "Do not block the area of the rear fascia where the radar sensors are located with foreign objects (bumper stickers, bicycle racks, etc.)."

Then there is the Rear Cross Path. "RCP monitors the rear detection zones on both sides of the vehicle, for objects that are moving toward the side of the vehicle with a minimum speed of approximately 5 mph, to objects moving a maximum of approximately 30mph, such as in parking lot situations.". Since the bikes are not moving at least 5 mph, it shouldn't be picking them up. RCP is only active in reverse.

Park sense is mentioned earlier, its only active in reverse (unless equipped with optional front sensors). It can be disabled via the button. "Use the ParkSense switch to turn the ParkSense system off if objects such as bicycle carriers, trailer hitches, etc. are placed within 12 inches from the rear fascia/bumper. Failure to do so can also result in the system misinterpreting a close object as a sensor problem, causing the “PARKSENSE UNAVAILABLE SERVICE REQUIRED” message to be displayed in the instrument cluster display."

When driving forward, the arrows in the mirror are blind spot system indicators, which may be what you are most concerned about. So you may want to think about how you could minimize interfering with them.

Given the number of complaints here from folks towing trailers, I don't think the WK2 does this automatically.

Thanks, that connector plugs in under the dash to the trailer control harness connector, then the wires are spliced to the connector/ harness provided by the controller vendor. Usually its easier just to buy a pre-made adapter/harness from the vendor.

Thats not going to help the OP.

ColdCase No question that adaptive cruise and blind spot are Godsends during cross country excursions.

But it sounds like your bikes are loaded wide enough that the side firing radar is picking them up. Hadn't heard of this before, my loaded bike rack does not interfere. Cross path and Blind spot (RADAR in fender) is an entirely different system than park sense (acoustic sensors in bumper) or Lanesense (camera on windshield). Trailer tow is irrelevant. Off hand, I don't think its adjustable, but there may be a menu item that turns cross path off. Or find a way to narrow the bike load or load them farther away from the tailgate as an experiment.

This load doesn't interfere with cross path (RADARs). If you're is loaded something like this, perhaps a trip to the dealer to ask if the RADARs are aligned properly.

Jaseinatl Hey all, thanks for the suggestion of turning off the parking sense. The problem is not so much with parking it's with driving on the highway. The rear motion sensors blink on and off every time I either hit a bump in the road or the bikes wiggle a little. The rack is heavy-duty, but the bikes weigh about 80lbs a piece so they tend to bounce around a little. The lights on the side mirrors register false positives repeatedly. Depending on how the bikes get loaded, sometimes one side will just always stay on.

And it wouldn't be a big deal it's just that driving from Atlanta to New Orleans is beautiful but BOOOOORING. Having the sensors and Automatic Variable Cruise Control (or whatever it's called) is a Godsend.

In our 2016 Cherokee, it would mess with variable cruise control and made the lane change indicators useless. I was told that when you have the tow package cable engaged in use (7pin?), it disables the rear motion sensors automatically because it knows there's a trailer or something behind you. That seems a lot better than just coping with the repeated and nearly random false indicators triggered by the bikes.

Our 2020 Jeep is a Grand Cherokee so it may not have the same problem since it's bigger. I'll be able to tell you after my trip to New Orleans from Atlanta next week. Thanks for the input, I am sure it seems silly to want the lane sensors to work and temporary tail lights for the bikes, but it was worth asking.

Must be a late model thing, My 2011 didn't come with a trailer brake controller cable in a bag, although it may have had some kind of trailer adapter.

jjmagoo ^^agreed all around just turn off Park Sense when the rack is on there and should shut up most of the whistles. I've got a '14 with the factory tow package.

ColdCase ^ what said, that's all I do.

What do you mean by brake kit cable? Your hitch should have a 7pin connector on the hitch and a 4 pin cable tucked under the bumper. Both of these are for trailer lights, power, brakes depending on the trailer you hook up. Some trailers have 7, some have 4 pin cables. A separate trailer brake cable is not at the rear.

I have the previous version Sherpa, a great bike rack.

Setting up Bike Rack with Towing Package

Hey all, I apologize in advance if I am in the wrong forum.

I purchased a 2020 Jeep Grand Cherokee High Altitude last year with the towing package. I have a Kuatt Sherpa 2.0 dual bike rack that I am able to use with only a couple of problems.
https://www.kuat.com/product/sherpa-2-0/

When the Bikerack is attached, the rear trigger and lane change trigger lights are constantly on. Backup up is enough to give you a migraine with all the screeching bells and whistles trying to tell you that something is behind you. I know, it's my bike rack.

We expected these problems with our first Jeep Cherokee that I installed an after-market tow package on. It worked great but the screeching bells and whistles.

Our new Jeep came with the towing package and an electric brake kit cable that I am assuming can be used to apply electric braking to an attached trailer. Surely this will bypass the warnings that there is something behind you when it is used.

Question a) Can I use this cable or another cable to somehow tell my car not to freak out about false readings that there is something behind me? b) can I use this cable to attach rear tail lights (breaking/turn signals, etc) to my bike rack?

Any suggestions or advice would be greatly appreciated. Thanks, Jase
