Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

I'm thinking the dealer didn't want to touch it for many reasons, most likely because of safety. Wouldn't want the liability if your brakes failing. As for retro fitting to have the stop go feature, there is a possibility for it to be added to the module but it could also need other hardware like many others have found with the difference in the module part numbers. This would be one of those trial and error project to find out. I don't know the sales code off by heart, but if you talk to ur dealer's parts guy that has good experience with starparts, could find out by filtering parts by sales code if any hardware is different from yours. I could try asking the engineers but they wouldn't be much help, since they don't know much about retrofitting an option such as this that was not factory installed. I will also look into any info I can get through my login for dealer connect. Any tsbs or star cases I can look into also. Will keep you posted on my findings.

Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

Looking more into it, do u have a Forward Facing Camera (FFC)?
I found some info on the FCW+ system and on how it is intended to work.
Hardware (2014 Grand Cherokee, Cherokee, and Durango only)
The primary sensors used for this feature include the forward facing radar located in the front of the vehicle in the grill texture and the forward facing camera located inside the vehicle near the rear view mirror. The forward facing radar using input from several other sensor to understand both driver intent and vehicle dynamics. These sensors included steering wheel angle, vehicle yaw rate, brake switch status, and throttle input. If the system determines the driver is actively driving and aware of the environmental conditions, it will suppress the warning assuming the driver is in control. Environmental factors also have impact on the function including snow, rain, fog, road condition and road slope.
To enable the feature
- The small LED on the Forward Collision Warning button on the center stack must not be lit.
- The vehicle must be traveling greater than 5mph.
The Forward Collision Warning system is not intended to do the following.
- The system will not bring the vehicle to a complete stop!
- The system cannot account for all driving scenarios!
- The Active Braking will not react on stationary licensable vehicle unless determined by both the Forward Facing Camera and Radar.
- The Active braking will not react on Street Signs, Guard Rails, Pedestrians, Animals, or other stationary objects. You will receive an audible and visual alert only for these objects if conditions are met.
Radar/Camera Fusion
To reduce the number of false positives in previous systems we have integrated Forward Facing Camera information with radar information to improve the robustness of the system.
- These improvements include redundant information to confirm automatic braking on stationary licensable vehicles which are classified as Cars, Trucks, Motorcycles, and Trailers.
- The forward collision warning system will still provide an audible/visual warning only on stationary objects which are not classified as vehicles if the conditions are met.
- Automatic Braking will be provided on moving objects with Radar only classification. This is the same amount of braking as maximum ACC braking.
NOTE: The system is not designed to replace attentive driving, it is only provided as assistance to the driver. Please see the owner’s manual for more information.

I took what training course they have for this system, and i remember in it saying this will not completely stop the vehicle if you do not react, it will however add aditional braking force if thinks you are not apply enough pressure to the brake pedal for the vehicle to stop without hitting the other vehicle.

And as for the tsb on the ACC, all i see is one for it not operating over 55 mph. Just a flash update.

Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

Good point,

I believe the camera that you are talking about is the triangle shaped form seen in this picture, behind the rear view mirror. I also have some other sensor by the mirror, which probably controls the automatic lights and wipers.

Seen better in this picture...



whereas by comparison, the 2011-2013 vehicles do not have that kind of mirror assembly. I think this Forward Facing Camera we got covered.

Your factory connection is our best bet for this endeavor.

I do not have a factory connection. I just happen to have come across forward thinking people. Getting a dealer to cooperate with your request is dependent on a number of things: making it clear who foots the bill; showing that you are not replacing intended basic function; that the parts you are requesting are bolt-on identical parts, though one is an upgrade. Then, there's the other thing: parts can be added to your VIN - all those little things you get added as a dealership option. Could be fog lights; could be roof bars could be the upgraded navi (like a 730 unit of the older Jeeps swapped over a 430 - or a new RA3 which gets the navi portion activated later). Flashes are NOT VIN dependent but components dependent. The VIN acts like a catalog of components making it easy to keep track of firmware upgrades. Again...depends on the unique relationship you have with your dealer. I will continue to pursue this though.

Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

If anyone else wants to help, I would like you guys to check on the rest of the components: Master Brake Cylinder; ABS Sensors; this Forward Facing Camera. There's more work to be done...but we are already seeing that it is not about sensitivity of detection but rather brake modulation. Please use the VIN used in POST # 10.

Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

This is interesting since I did not think that the vehicle would actually stop without the ACC with stop feature. Could it be that the Overlands have this built in pre July and the software update activated it?

No, read the very first post, it was a hardware change mid year.

Understood. However the link above claims the jeep came to a full automatic stop with the pre July NH1 hardware.

If I am not mistaken, the run-of-the-mill Overlands do not have this technology. It has to be purchased as Advanced Technology Group.
I doubt the full stop. I know mine doesn't.

Anyways, since I am getting zero help from no-one else, this project is going slowly. I have not had time to check back from the dealership. The Bosch folks were unhelpful and asked me to check back with Jeep though they admitted it is their product. I have also filed a case with the Jeep tech support. I have not heard from them back, but it's only been 2 days. The lady over the phone was not sure what exactly I want and why am I not asking the dealership. I explained that the dealership doesn't know and this has to be asked of engineers at the factory.

Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

ACC with stop not stopping anymore


This thread ^ seems to have exactly what we're looking for but in reverse? He somehow went from ACC w/stop to ACC w/o stop.

Re: CROWD PROJECT: Retrofitting "STOP" on the 2014 JGCs with ACC

Interesting, I hope the guy keeps us informed.
I have done little progress - well maybe considerable progress depending how you look at it.

- Bosch told me that I should call Jeep.
- After I called Jeep, several days later I received a message along these lines: "Currently Chrysler does not have a retrofit kit to add STOP functionality to vehicles that did not come with it. Jeep engineers do not recommend installing components to the car that were not part of the original specification".
- I have sold some old Subaru car parts to acquire funds for the ABS control module.

This statement did not answer my question which was very specific as to what parts were different between different vehicles. I did not really expect the answer, as the question came from a consumer not from a dealer tech. The good news, as I interpreted the answer, is that it can be done, otherwise the answer would have been along the lines that the work involved so obscure that it cannot be done and it would void the warranty. I am still working the dealer angle.
