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

[vincentw56]

I have a new Dasm on my truck as i already purchased, i have no idea it it will work for some reason i now have a electronic stability warning light on.
Dealership is in the morning, by the time this works i will probably crash my truck

Needs calibration and removed from plant mode.

Trucks been at dealership for 8 hours and as promised they screwed it all up, i wonder if i can just pick it up now and re add all the changes with alpha obd

Yes, they updated something which reset your settings. Nothing they will do so you have to add it back.

Yes, I suspect they performed the restore vehicle configuration, and reverted all your alfaobd changes. The alignment completed and passed, so that’s all good and won’t need to be done again. I’d say just grab the truck back and check all the settings with alfaobd.

I wish you could save a setup in JScan (maybe you can in alfa?) so you can just reupload all your changes.

You can in Alfa easily.

Can't in JScan, sadly.

In settings, trace and restore.

In settings, trace and restore.

Damn! I will check that out. Thank you

Hello, good day; Thank you for your support on this forum, especially Jimmy07 and FM45. I've already installed trailer brakes, Vision 360, adaptive cruise control, auto park, and lane sense. But I'd like to know how to fix the humidity sensor, the rearview mirror auto-dimming, and the rain sensor?

Follow the first post. The PDF has the info on the rain sensor and settings for the auto dim headlights.

Thank you very much, what happens is that when I activate the rain sensor the handbrake warning light comes on, and until I turn it off it goes away, and on the scanner it appears as bcm impassable, that there is no connection with the interior mirror, nor with the sensor, not humidity sensor, and I don't know if it refers to the lines like defrosted that are in front of the DASM?

Do you have the rain sensor installed?

Yes

I got a interesting issue maybe it pertains to this. I completed the adaptive cruise control upgrade things worked great for about 2 months. within the last couple weeks I've had a interment communication issue with the abs/hcu module. Originally i purchased used through lkq so warranty covered the replacement(win lol) . yesterday i finally got around to swapping the parts out. I got all the lights to clear with the exception of the service esc light/message and service trailer brake warning message. i only have one code stored in the abs module a u1216, i verified the connections for the dasm they are good. i haven't attempted to use the adaptive cruise yet so I'm not sure if that function still works. can any one point me in the right direction?

You didn't tell us the year and model. Did you replace it with the correct module?

i have a 2020 1500 came off a 21 1500 . i ran the vin from the donor truck and it showed to have adaptive cruise.

If your truck came factory equipped with FCW but not ACC, you need the following: (see attached file for additional information).

HCU: 68415320AA ACC w/Stop and Go - $265.55

ABS Module: 68436462AJ Adaptive Cruise Control w/Stop and Go], [Adaptive Cruise Control w/Stop and Go] After 06/06/2018 - $200.64

ACC Button - 68309592AD SWITCH. Speed Control. Right. = $57.05



Lane Keep for 2021 RAM

Requires:

Center Stack 68312620AG – $468.60

Thanks for this summary. I have FCW but not ACC. It looks like ABS Module: 68436462AJ are no longer available. Some website says 68436462AJ is replaced by 68728726AA. Can anyone confirm 68728726AA works? Thank you!

I am looking too and getting the same thing. Though it doesn’t seem like the HCU or ABS module are in stock anywhere.

So i had a issue of the abs module saying it lost communication with the dasm but everything worked as intended, i just had a pesky esc light that came about after changing the abs module. Not having esc was fun for a whole 45 minutes ( leaving parking lots sideways without throttle cut woohoo). But come to find out I added a fuse to the wrong circuit in the fuse box. BE SURE TO USE FUSE 66. I had it in the position right above it. NO BUENO
