ACC (Adaptive Cruise) Retrofit >> Underway, PSA

[DC3]

It seems my OCD and my curiosity have me retrofitting a bunch of stuff to my Gladiator (Paddle Shift Steering wheel, Selec-Trac, and now ACC).

There have been several posts questioning whether the adaptive cruise can be added after purchase. It seems it can. But it is definitely better to buy the Jeep with this option rather than retrofitting. My Gladiator is so modified that trading it for a new Gladiator just didn't make sense. I also enjoy a challenge and it has been fun to understand the Gladiator/Wrangler electronics systems.

I will update this post with additional findings, photos, and answers to questions regarding the swap. The main components required for the ACC swap are:

Required Components (~$1,600) (~$2,000) with price increases since the original post. Updated 01.22.23

• Camera/control module
• camera jumper harness
• ABS Module $250$370
  • Part# 68461644AC*
• ABS Controller ~ $150 $190
  • Part # 68438383AA*
• ACC Steering wheel switch

"Optional" components - These are not required for the ACC to function

• Heated windshield jumper harness
• heated windshield (specific to ACC)
  • ~$800

* Please confirm the part numbers are appropriate for your VIN, there are several versions of the components.


As I began installing components, I discovered numerous error codes which resulted in additional components (to comprise the list above). I do not have adaptive or standard cruise functioning currently. I have to calibrate the ACC ABS valves and the ACC system. I haven't discovered how to do this with either Jscan or ALFA OBD, I may need to use the Micropod with Witech 2.0.

While I don't have the system functioning, I remain confident it will soon be operational.

I realize this swap is not for most but I couldn't help but embark on the project as a challenge and opportunity to answer the feasibility question once and for all. The worst part is that I am running out of things to retrofit.

I admire your persistence. Good luck.

Best of luck!
Really curious if this will include the emergency braking feature.

So how far have you gotten on your acc/fcw retrofit? I’m on that road now have configuration problems I’m currently dissecting. I’ve found the radar camera on eBay for $180, which is way I figured it was worth a shot. Why are you replacing the abs module and and controller? Are they different?

the overhead wiring which includes the radar camera connector is68357530AD.

Yes the emergency braking feature works, as does the automatic brights

The ABS module and controller are different, I imagine it is for emergency braking. I am fairly certain the system will not work without it.

My system is fully functional, the only error I have is an error with the radio frequency hub module but this has no apparent impact on function

did you have to use the dealer at all? I keep getting a configuration error with the dynamic cruise configuration and adaptive cruise configuration. . It may have to do with the not having the correct abs module. Can you give me a dump of your settings from alpha OBD?

 

[DC3]

If you didn't replace the abs module, I am certain that is the issue. I didn't change mine at first either, same issues. The jeep I swapped is currently out of commission and I hope to have it running "soon" but I am not able to connect to it now. (Long story). I have another gladiator with the factory acc and will pull logs from that today. I will pm them to you

I did need to use the FCA micropod and witech to finally activate the cruise and go through the calibration. This is the same device the dealer uses.

I have another aftermarket programmer but the jeep control modules wouldn't let me make changes

Impressive project. Nice work.

Thanks! It took some perseverance and digging to get it done.

Thank you, this is good info. However, it can't be done without the expensive dongle right?

or going to the dealer. I have contemplated renting out my adapter (dongle just doesn't feel right in this context) for those who need it, but I haven't gotten past the concept.

If not the FCA dongle, then an equivalent master tech diagnostic computer would work (Bosch, Snap-on, other similar tools). I tried using my Launch x431 Pro+ but I couldn't get it to work, even though it is designed to work with the FCA SGW. When I had my windshield replaced, they used a Bosch computer.

Good, if we find a Wrangler that meets my wife's demands but is lacking the "advance safety group" we could hire you to fix that little problem.
I've found several close matches but most Wranglers were ordered by dealers without that group - or they could not get it because of shortages. (instead they got the stupid sky roof - seems they are stuck with those)

I doubt you’ll be able to use a used DASM (radar camera). That’s how it is with doing this on a Ram, and it’s basically the same DASM. The original VIN and current VIN stored in the DASM are locked, and unlike most other used modules, it will not pick up the VIN of the next vehicle it’s installed on. This stores a configuration mismatch in the DASM, and it can’t be calibrated. I’ve tried everything I could on a used DASM, but even CDA 6 doesn’t even give the option to write to the VIN counter.
