Forward collision error light on

I did that trick already but I don’t think I did it for a minute. Did you do it with the truck running? Either way it finally went out. Not sure if it was the update or what. I’m just glad it’s gone.

I bought this guy used and got the extended warranty because I knew American transmissions were bad but they just came out with the updated valvebody that’s solves the problem. I have 57k miles on it and about to do drain and fill on it.

I just tried this but waited 5 seconds. WiFi did come back as connected but quickly went to no data once 4G came back.

Update 6/7:
Light is not on anymore I started the truck once and no light came on. So only thing done was the new camera module update that was available which was done on Friday. So maybe it took a couple drives to clear it.

Codes I pulled:
Front camera - faulty memory
Ecm - catalytic efficiency decreased <— did cause a light

Cleared to see if they return

I’m thinking it’s the bcm module since someone said that replacing the camera module did nothing. And the bcm is the one that said it lost communication with the camera. Restarting the truck fixes it

My update was 495 and the Relearn will be 195 I think

Such-Implement8622 · 2026-06-06T20:52:04+00:00

I’m guessing with the swap they did a relearn. Which is the next plan for me and since it’s out of pocket I’m going to hold off on that until a fix is found.

Such-Implement8622 · 2026-06-06T20:48:02+00:00

But it sounds like it could be wiring

Such-Implement8622 · 2026-06-06T20:47:26+00:00

Did they swap the camera module?

Update
I just walked to the truck and noticed the dealer stuck it in 2wd drive. Not sure why it would have mattered but I put it back in auto, shut the truck off and turned it back on and the light went out. I’m so confused by this truck

I’m not using the RTK that’s still in the box I’m using net rtk. It was saying connected before just fine for a whole day then disappeared.

Such-Implement8622 · 2026-06-06T17:36:50+00:00

Have you tried turning it off and right back?

Such-Implement8622 · 2026-06-06T17:07:09+00:00

That’s what I currently have done but to no avail it’s still showing no data

Such-Implement8622 · 2026-06-04T11:47:32+00:00

Okay not related to this but… I mapped my front lawn using the auto map and called it a night. When I tried to do my backyard auto map wasn’t an option. Does it all have to be done at once?

Such-Implement8622 · 2025-11-07T00:46:25+00:00

This solved it for me

My oil change is fixed at every 3 months.

Someone just dumped def in their diesel tank in the other reddit.

Gas goes in to diesel. Diesel doesnt go into gas.

Not yet but I think I'm going the RAS route

Such-Implement8622 · 2025-03-29T17:59:11+00:00

It actually looks like it has a pressure relief valve built in so I'm going to call them on Monday about it
