ACC/FCW Unavailable Service Required

[RamCares]

I see this is an older thread I am having the same issue with my 2021 Laramie. My dash shows the following message. " AUTO EMERGENCY BRAKING (AEB) UNAVAILABLE WIPE FRONT RADAR SENSOR" Where is the Front Radar Sensor location. I CAN NOT find anything on the web to assist,. Dealer stated " That wont be covered by your extended warranty"

Please Help. If you need more info to assist me please let me know.

THANK YOU

Hello,

We're sorry to hear about this issue. If you decide to move forward in working with the dealer on this, we'd be happy to offer an extra layer of support. Please feel free to reach out via private message. Additionally, per page 147 of your Owner's Manual, "The sensor is located in the camera in the center of the windshield, on the forward side of the rearview mirror."

TLDR; After dealer visit my Adaptive Cruise isn’t working with the error in the title. Anyone else have issues?

Took my truck to the dealer to finish some “We Owe” stuff and do a couple TSB’s.

Work Done:
Installed Power Side Steps and flashed sales code.
Installed Trailer Brake Controller

TSB for HK Volume
TSB for sudden brake assist when in reverse
Asked them to inspect Lane Sense to see if camera can be recalibrated after lift as it does not work as well as before the lift.
Alignment

Somewhere in there (Lane Sense would be my guess) they have completely disabled the Adaptive Cruise Control and the Forward Collision Warning. Shortly after the truck starts I get the two orange icons in the picture below that appear to show them as disabled. If I attempt to turn on FCW in the UConnect settings it checks the box and after about 2 seconds beeps at me and unchecked it. If I attempt to turn on ACC while driving I get the message “ACC/FCW Unavailable Service Required”.

They are aware of the issue and have ordered a new “module”. They said it would take a week to get the part and then they would need to keep it for a week so they can drive it everyday to program it. They already put over 80 miles on my truck in the 2 days it was there.

Outside of letting them do their thing I just wanted to reach out to see if others have had issues with either ACC or FCW and how it was remedied because it seems to be a grasping at straws situation going on at my dealership and ACC was the single most important must have when I purchased this truck.

For a little more backstory, this is my second 19. I traded in a Limited to go to the Laramie because I had all kinds of problems with the 12 inch screen and finally just had enough. I hope this is an easy fix and will be behind me in 2 weeks time but I envision a scenario where this drags on and I ultimately get sick of this truck too. Which would be unfortunate because this is the first vehicle I have had where I went all out to get it to how I wanted it to be.

Oh, and as you can see in the picture on my drive home from the dealership I received an error to service the Tire Pressure System as one of the wheels just completely fell off the map. This came back after a battery pull and a couple of starts and a trip around the block.

Did you ever get the acc fixed I’m having the same problem

My 2500 Larami keeps dropping out of cruise control and now has a ACC FCW error. Have it going to the dealer tomorrow.

Is there anything I can check to resolve?

How did everyone make out on this? I have the same exact issue on a 2023 with 8,000 mi on it. I made an appointment with the dealer but they are a month out before they can even look at it. We've got a road trip coming up, looks like we're going to have to take the old trusty Kia.

I don’t have this vehicle anymore but whatever module the dealer replaced fixed this issue. I didn’t have any problems with it after that.

Did you ever figure any more out with this issue. I'm having the same exact issue on 2021 1500 Laramie?

I've had the alert come and go many times now and it just cleared again last week. I removed the cover behind the rear view mirror, cleaned the windshield and then also cleaned the lens on the module. After about 30 miles, it cleared. Stayed cleared for a week, then came on for a week and now is cleared again for the past few days. I recently got an OTA update on my Uconnect and the alert cleared soon after.

If it continues to come on, I'll see if AlfaOBD or someone with a tool can disable the option on my truck so it never comes back!!!

 

[scottmoyer]

Ok, I drove about 65 miles towards Tampa yesterday and the lights came on again. I stopped at Lakeland Dodge to see if they could tell me if I have a code. The service writer didn't tell me any codes came up, but gave me a printout stating that I have the ABS module recall that needs to be done.

Based on an earlier post in this thread, it was mentioned that the ABS sensor was sending bad signals causing this error. I wonder if that's the issue with mine. Driving at slower speeds, the alert goes away. It came back on two weeks ago after driving at 75mph to Daytona. It then went away, but came back on yesterday while driving 75mph towards Tampa. Hmmmm.
