How to: Add Adaptive Cruise Control, Lane assist, FCW & Auto Hi-beam to Ram 1500

[hammersfd]

Well, I went for it and had the ABS recall done, and so far everything is still working as intended. I did tell them I changed the ABS module, and the paperwork notes a mismatch. Fingers crossed, but seems to be good!!

i recently purchased most of the parts to do the swap. the acc switch is currently on b.o. through fca forewarning y'all, lucky for me i have a not so pretty one to get me by for testing purposes . my local dealer friend said 9 in the country and only dealers have them. but can someone shed some light on the semi auto park? i know you need a new harness and valances after reading the 68 pages. i did not see a definitive answer on if you need 4 new park sensors for the rear or if the ones i have now will work. i ran a vin from a truck with the semi park/ fca/acc/lka and came up with part numbers 68404408ab and 68404409ab for the valences and 6860453ad for the harness. i checked the sensors and all 4 show to be different then my 2020 BH with factory front and rear park sensors w/ rear park sense. my vin is 1C6RREBT3LN128815.i ordered a used abs module from lkq that is due in later today supposedly from vin: 1c6srfjt0kn787071 and a used dasm from vin: 1C6SRFU95NN227812 due in hope fully the next day or two. lets see if lkq has them inventoried correctly. new trims and bracket for dealer, i ran the vin from the abs module and it shows the same part number for my factory BH rearview mirror so i believe i should be good on that as long its not a catalog error. I upgraded to UC5 on my truck a while back so i have a used screen coming for that not due until after Christmas. the last piece to the puzzle is the windshield and the install. cheapest i have found is safelite running at about 435 installed. list on a new one from the dealer is 1125.00 /part number 68275585ag part number pulled from same vin as abs module.

There isn't a definite answer on needing to replace the sensors. But you do need the outboard sensors in the rear. My posts tells you what you need.

okay thank you. for future reference part number for valance pieces
the number with the CH's is the aftermarket part number for those on a budget.
single exhaust: 68404394aa and 68404395aa (ch1147112/ch1146112)
dual exhaust: 68404392ab and 68404393ab (ch1147108/ch1146108)
park sensor: 6mk25tzzaa
harness: 68360453ad

So in the end it took a while but everything works as it should ... thank you very much for your help once again

How did you get it to show up?

Looks like you are at the same stage as
Me, got a used dasm and jimmy making me a harness, I want to assume that the high beam and rain sensor I currently have on my truck will attach the same to the new windshield, lucky for me when I upgraded to uc5 the lane on off button was installed. I think I will get the dasm pre cabled then get windshield replaced then work on trying to figure out the abs modules. Does your truck have high beam and rain sensor already installed

The rain sensor and high beam sensor are 2 different modules. The rain sensor will work no matter what windshield. The high beam will be replaced with the DASM. Your current high beam sensor is attached to your mirror. It will be removed when you put on the new mirror. Then the camera in the DASM will be used for high beams.

I got the windshield installed today. Played with trying to get the DASM hooked up, but for some reason cannot get it to communicate or I am assuming that it is not communicating. I have my power ran to pin number one ground ran to pin number Four can high on six and can low on seven. I could be flipping those two around. I am currently driving so cannot verify at the moment I should reach my destination in about a hour and a half. I will keep playing with it then but my question is is there any way to verify that the DASM is communicating? I am getting an adaptive cruise control message. ? I am getting a adaptive cruise control message and lane departure warning message as well as for collision warning message oh, and a service trailer brake model message.

 

[tristainbdts]

OK, got to stopping point to double checked all my connections verified that I do have power and ground at the DASM verified I have can high going to Pin 6 and can low to pin 7 on the dasm I do not have any stored fault codes in the BCM. But still getting a ACC/FCW UNAVAILABLE SERVICE REQUIRED. KEEP IN MIND THESE ARE USED PARTS. I do not have the lane. Keep assist switch installed unfortunately that won’t be delivered until Thursday. The following day after Christmas is that what’s causing my messages so far? Any help would be greatly appreciated.

You had the dealership run the alignment on the DASM, correct?
Did you swap out the ABS/HCU module?

Abs yes,align no. Unless I misunderstood the pdf thought it said I should only have the fcw off error.

If you install a dasm on a truck that hasn’t had one, it’ll need to be aligned by the dealer.
If the dasm is used, you have to make sure they follow these instructions:

I can now confirm that a used DASM can be used for this project. I successfully calibrated 2 used ones in my truck this weekend.
When you have the dealership do the calibration, tell the tech to perform the following on the DASM:
1) Perform the enter plant mode routine
2) Clear all DTCs. This will get rid of the vehicle configuration mismatch, and allow the calibration to be run.




Then they can run the calibration like they normally would:

After doing some research on the used side of things model years 19,20,21 all have different part numbers and 22-24(possibly 25) used a different number.

19:68320948AF( n )
20:68454267ac
21:68475159AE(f,g)
22-24: 04672891AB(c)

I was having issues with communication on 22-24 module in my 2020.

I ordered ones from a 19 and 21 from Lkq let’s see how that goes. Will up date after the new year.

yes to both but not from the factory. The auto high beam use a different kinda light sensor that is attached to the rearview mirror if you don’t have fcw. If you do have fcw the dasm is used for it. I found some info out on used parts and part number be sure to check it out.

got everything all working today. while installing the plastic covers i noticed the windshield i got installed has lines for defrost like the back glass. what would be the process for hooking that up?

It’s never really been addressed, but another harness would need to be built for it. I would need you to look at some connectors to see if any/how much of the wiring for it is present.
Is there a 10 amp fuse present in F41 of the engine bay fuse box?

I've never seen a need for it.

Which method did people do for the hcu abs relacement, was it from the wheel well or from underneath

 

[Jimmy07]

Which method did people do for the hcu abs relacement, was it from the wheel well or from underneath

Most of the work is done through the wheel well (easiest to remove the liner, but not necessary), and through the top of engine bay. Really, the only thing I do from underneath is pull the wire harness tree off the bracket, and the last bolt off the bracket to pull the module out from underneath, and shove the new one back up there.

no to the fuse. looked at some diagrams from pro demand and the wire is ran from the fuse box but terminates in the connector for the headliner harness( on the left side of the dash cluster area)
