Interesting phone call, service manager quoted me 7k to install adaptive cruise control on my 2018 compass.... for non Trailhawk compasses, 1700 to change front ends to trailhawk with steel impact bar, they also have to calibrate the radar if it’s removed. Putting on bigger tires? 97 dollars to calibrate speedo, that lets you keep the warranty on everything. The ACC they said they have to change the body control module as well as the drive train module as well.

The only Jeep vehicle that you can calibrate the speedo for bigger tires is a wrangler

Do you have the front collision warning/breaking system (with the radar eye, etc)? I think if those parts are installed, the car should already have all the hardware required for ACC.

The dealership said they would calibrate the speedo for my compass, when it comes to the ACC, the manager was a major dick about it, saying yeah they could, but putting an outrageous price on it so that most people won't think twice. I told him I have the Forward Collision Warning Plus, he still said he would have to install new body modules and drivetrain modules and that apparently adds up to 7k.... No other dealership will look at it though, so i'm going to ask for an estimate lol. I'll keep people updated as I go, but for right now, i'm saving up to do the tires and front end swap and adding the skid plates. 2500 dollars later, i'll see where I am at lol.

You can ask for the part numbers as well. If they need to install a different body modules and drivetrain module, their part numbers should be different than what is now on the car.

For what I learn playing with AlfaOBD is that the body module is the same for all models. What it changes is the vehicle configuration.
In simple answer. Even with the new module. Jeep won't turn in adaptive cruise control. Because those functions are turned on by the VIN configuration.

In other words. Get yourself some AlfaOBD. And turn on the feature your self.

This is the route I'll be taking with AlfaOBD. Just working on other cars so not getting to it anytime soon.

I am 99.9% that what your dealer is asking for is wrong. There is no procedure for retrofitting the ACC, so he just made stuff up. I've seen this with my dealers up here a few times, but little did they know that I knew more about the car than they did ... sad ...

I'm willing to bet that as Jaime said, it just needs to be turned on, and maybe a module or 2 need to be flashed.

Haven't posted in a while. Been busy with other stuff. I bought the new steering wheel controls for ACC. Haven't got a chance to install them yet. Once I do, I'll enable ACC in the BCM and see if they work. My Jeep doesn't have the radar distance sensor, so that might be next if things go well with the buttons. At the very least my wheel wont have depressing blank spacers.

Hey n4cr2k, By any chance, do you have the part numbers for ACC controls.

I was impatient and bought the part for the Cherokee instead of waiting for the part number for the 2019 compass. The wiring harness looks correct and seems like it should be a drop in replacement. Just haven't had a chance to pull the steering wheel to try it out.
