Lane Keep Assist "Unavailable"

Theweavman · February 19, 2020

Good luck, I’m still waiting on the parts my dealer ordered for the repair of the side detection issue..... I will post, once they come in and the parts are installed, at least I’m able to keep and use my truck in the meantime

What issue are you having with side detection? When I check my codes, I get one for side detection. I clear it and it comes back. No light though.

DIC reads “Service Side Detection System” every time truck is started, and no lane change alerts are working.....dealer said their equipment said my system needed to be reflashed, but when they tried my computer would not accept the the new reflash, they said GM told them to replace sensors and side mirror cameras, been waiting on parts now for over 2 weeks now so far

Ok thanks. I don’t have those messages and everything works fine

Great, glad your not having any similar problems, my truck was great prior to the 10 software updates that were done, thats when my problems started...... hopefully they will get them resolved soon, love this truck otherwise

Does anyone get audible alerts when nearing the edge of a lane? My lane detection icon on the gauge cluster will go from green to amber and then the electric steering will attempt to move me back into the center of my lane, but I never hear any warning or chime. Is this behavior normal?

What I found on my Tahoe is the exact same thing you experience. I do get the seat to vibrate if I am about halfway to 3/4 over the line. It doesn’t alert all the time when I go over the line. I have tried intentionally and it wouldn’t do it. I have drifted over the line and it warbled needs. I think it takes into account the force on the steering wheel. Lots of things going on behind the scenes. Also there are setting for audible alert or seat vibrate in the infotainment section under vehicle safety alerts. Hope this helps

For one drive a few months ago I changed the alert settings to have seat vibration. There is no way to have both the seat vibration and audible alert selected simultaneously in the touch screen menu, you have to pick between one or the other. I did get the seat vibrating and the red lights illuminating on my windshield somehow when I was moving into a turn lane. I was confused if this was the lane departure alert or the collision alert because I thought that the red blinking lights on the windshield were for the collision alert functionality. But have never seen them again. I went back to audible because it also uses seat vibration for the parking sensors. I prefer the audible alerts for my parking sensors.

But I have never received an audible alert for going out of my lane, and I have intentionally drifted purposefully many times. Like I said the icon turns amber from green and the electric steering tries to push me back, but if you go further out of the lane, the icon turns off and the electric steering stops trying to steer me back. No beeping, never.

Actually it isn't so bad. My wife had a 2015 and now a 2020 Nissan Rogue and the lane keep warning is very annoying so we turn it off. Constant beeps unless you're always perfect in your lane and don't move around potholes! Although if there is something out of the ordinary I would rather it be right rather than wrong. But if your GM truck is doing the same thing I'd imagine it is normal, hopefully.

It just seems odd that the seat will vibrate if you have it set that way in the menu, but I won't hear any beeps if I have it set to the audible alert. I would have thought that the seat vibrations were the precise equivalent of the audible alert, so if you received one, you would hear the other.

I’ll change to audible and see if I can get to alert tonight.

You must have LKA - Lane Keep Assist. (the one that nudges the steering)

If it and you are able to stay in the lane -- no warning from LDW (Lane Departure Warning).

LDW should give a warning if you cross the line (or at least go beyond where the LKA tries to help) without using blinker.

FWIW, vehicles without electric steering (like the HD pickups) can have LDW, but not LKA.

If it has LKA it will also have LDW, but not necessarily the other way around.

It certainly doesn't give me any warning when crossing the line. This happens all the time. Cross the line after the electric steering tries to nudge me back and then nothing happens. Normally the green or amber lane indicator on the gauge cluster also turns off at the same time since it isn't detecting a lane any longer.

However the lane keep assist electric steering is very accurate and does try to nudge me back over appropriately. And also, the green lane icon does turn amber when it senses I am getting near. There is no audible warning though what so ever and I've owned the vehicle for two months now.

I've tested it out in depth and it will always appropriately steering the vehicle back over within reason. But if you force it and cross the line without using the turn signal, nothing happens.

By the way, I'm looking at the build sheet that GM sent me.

Anything that pertains to "lane" are only these two items:

UKC - LANE CHANGE ALERT WITH SIDE BLIND ZONE ALERT
UHX - LANE KEEP ASSIST

Is it possible that the vehicle is not equipped with lane departure warning?

Thanks. Interested to hear what you hear, or don't hear.

According to this video regarding the 2015 GMC Sierra, the red lights that illuminated on my windshield awhile back were related to the collision warning system.

However, this video very clearly indicates that an audible tone should be produced when the lane keep assist icon turns from green to amber. I'm not hearing that audible alert at all, although all of my other audible alerts seem to be working properly, such as the front and rear parking assist warning. I can't imagine that sound just wouldn't be working if all of the other audio works fine.

But then you see this video here with a 2018 GMC Yukon Denali, you can see his lane keep icon switching from green to amber and there is definitely no audible alert being produced. Although he does get an alert to "retake steering" when he takes his hands off of the wheel, which I have never seen either. Of course the Denali has an entirely different gauge cluster as well.

And then here we have a 2016 Tahoe being tested and there's no audible alert for his lane keep assist or collision warning. Just amber icons.

Theweavman · February 20, 2020

Can’t speak to an audio alert for lane change system as all I remember is that the little yellow light in my outside side view mirrors used to light up yellow on start up and again if another vehicle was approaching on either side..... now I have no illumination in ether mirror at all, and the DIC warning that my side detection needs service, which just by the way, my service advisor just left me s message that the parts they were waiting on have now arrived, and I need to make an appt to have them installed... probable will get my truck back in next week, hope it all works
