Forward collision and lane keep assist still a problem on 2022 refresh?

[Kaylan Steen]

That's not how a 3 spade fuse works. The Micro 3 Fuse is designed to protect 2 different output circuits from a single power source. Power flows into the fuse via the middle prong and out via the 2 outside prongs. Only the middle spade is the power source, so you should only see voltage on the middle. A fuse is only as good as the system in which it is used. One aspect of the electrical system that has considerable effects on the performance of the fuse is the quality of the connection between the fuse and the cable it protects. If you don't have continuity between the power supply and circuit it feeds it will not work. All you have to do is test the middle spade. The only true test is the readings at the end of the circuit  which would be at the ecm. The ecm is what controls work properly. Hope I explained that well!

thanks for explanation.

Disconnect battery for 15 minutes reconnected and has not come back for around 100 miles so far, canceled dealer order part told head of service what i did as recommended here that worked for others and that if acts up again i will let them know. 

 

Pulling and reinstalling F11 Fuse didn't work, disconnect and reconnect battery for 15 minutes then everything works again.

I’m having the same problem on my 2022 HC.

It’s been to the dealer 3 times and I’m on my second front camera. Just picked it up tonight, they said it was fixed and it’s not. I will be calling tomorrow.

Lane Assist, high beam assist & front collision detection only worked for the first week I bought the truck

I’m a gm certified paint tech working at a Chevrolet dealer and got lucky and scored a 22 rst 4 door 1500 rst duramax fresh of the 18 wheeler for cost thanks to my general manager. Same problem so I got on the gm computer system at work and printed out the instructions to fix. Pull Right side fuse panel on dash top row from left to right 10 amp fuse pull it count to 10 install and problem is fixed

Got a new truck about a month ago… happened to me yesterday in the new truck as well. 
pulled the fuse out, bent the legs and put back. Problem solved again… hopefully it stays that way.

Good to hear that it worked on the new truck too. I sold mine a week ago. I'm going into freight hauling, so I bought 2 Ford Transits over the last few weeks. I signed a contract with a company and didn't need the truck. It only had 9k miles on it. I'm just glad my little fix is still going strong!

Man am I glad I found this discussion! Picked up my refreshed '22 Duramax less than a month ago. Just rolled over 1k on the odometer before issues began. The only light I got on my dash was during inclement weather, so I chalked it up to obstructed sensors. But days later, I noticed to lane departure on the dash, or seat feedback, no adaptive cruise, and no automatic hi/low beams. I was going page by page in the owners manual to see if I missed something before contacting the local Chevy dealership, but I'm going to try the fuse fix on my lunchbreak tonight! 

 

Thanks to Kaylan and everyone else for the discussion!

So my 2022 high country lane assist and adaptive cruise control are "not available".  Problem is fuse F11 in passenger fuse box is not the overhead camera..  mine says "seat/clm"  I do not see any fuse labeled overhead camera or anything like that...anyone got any other suggestions??

[Kaylan Steen]

It's the F10 fuse that isn't making good contact. Tweak the spades just a tiny bit, wait 10 min, and reinstall. That's what fixed mine permanently. When temps change, the fuse will not make good contact, so doing a slight twist will help to keep it tight.

[Kaylan Steen]

Just FYI, it has nothing to do with any of the cameras.

[curtisp]

Thanks. Trying now. 

[curtisp]

Didn't work. Gonna try to disconnect battery cabled for hard reset...next step will be to get the dealer involved.

FWD collision alert light appeared a cpl months ago.  All other systems working normal.  Just noticed yesterday that the cruise control system won’t work while the FWD collision is having issues.

 

Tried everything….

 

Pulled fuse 10

Pulled fuse 11

Bent the forks

Disconnected battery for 10 mins.

 

Anyone have any other ideas or is a dealer visit needed?

You'll need to reset the ecm. Remove the negative terminal from Your battery. You will need to use a socket wrench to do this. Next, flip Your headlights on. This will fully drain the computer, or ECM. Wait for around 10 to 15 minutes. Then, turn the headlights off, and reconnect the negative terminal to Your battery. Start Your engine, and the computer should be reset.

You may have a faulty fuse too. Sometimes, they won't look tripped, or damaged in any way. You can also add a little electrical grease to it as well.
