Coding The Grand Cherokee

I am frequent visitor to a few BMW forums and they always have coding discussions that I would think would apply to, at least, the 2014+ Grand Cherokees. They are able to change a lot of the settings that are set regionally, such as US spec and EU spec brake lights and even change the traction control to EU settings(much less intrusive). That example is just scratching the surface, more examples can be found here . (BMW Forum)

My question is, does anything like that exist for the Jeeps? I feel like it would be possible to do the same type of coding on the Jeeps. I'm just curious if anyone has seen any tools to do this on the Jeeps? It's pretty cheap,relatively speaking, to do on the BMWs even if you buy your own tools to do it and not rely on a vendor.

Something like that would make a lot of mods much simpler and allow people to really customize settings of their cars how they want.

Just throwing this out as a discussion. I personally have not found anything outside of going to the dealership. I'm sure they have the capacity to do this but I would rather be able to do the customization myself.

EDIT:

With the coding, they are also able to get rid of hyper flashing with the LED lights without having to resort to resistors. Just one potential use for being able to code the car.

I'm not sure exactly how much you could change, but it is possible. Here's an example for ya.. I recently had an OEM remote start installed on my '11 Laredo at my work (CJDR dealership), and the tech who installed it activated the courtesy lighting in my door handles and door pockets simply by turning it on when he had it plugged in. I had no idea they were even there until he turned the option on..

If I have a chance, I'll hook the WiTech system back up to my jeep and see what else can be changed. No guarantees, but if you can activate interior lighting, I'm sure there's other options that can be changed as well.

Hope this helps!!

Re: Coding The Grand Cherokee

Definitely see what can be done with the factory tools. Mainly, I'm curious about changing the rear turn signals to amber instead of having 4 rear back up lights. My guess is that it can changed in the coding along with light bulb swap and no actual wire changes. The region code may need to be changed vs just a single option though. All speculation though at this point without actually seeing what the dealers are able to change.

It would be interesting to see what options are available to the dealers. Would you be able to get a 14+ on there as well?

Re: Coding The Grand Cherokee

It would be nice if you could code it to fold the mirrors when you lock the doors. That is something you can code on the X5. Our mercedes lets you set that option from the settings menu.

That would be nice, yes.

A couple of others:
> allow QL to lower suspension to Entry/Exit Mode even when doors are open
> change turn signals to five blinks instead of three for the quick lane change mode (unsure as to its 'official' name - when you tap the turn signal stalk)
