Back Up Camera Grid Lines

[Autobyfox]

So I leased 1 2020 Bolt LT in early September. I also work for a Chevrolet Dealer in Rochester Hills MI for the last 24 years. First of all the Bolt is one of the best cars I have ever owned and that covers a lot of vehicles. I have one issue though that is driving me crazy. The Back Up Camera launches immediately when I shift to reverse, problem is the grid lines do not show up. I have waited up to 20 seconds after starting before shifting to reverse and same story. As soon as I go back to park though the camera display shows the grid lines. Back to reverse and still nothing. Only way they seem to reliably work is when the vehicle is warmed up for a few minutes before trying to shift to reverse. Anyone else notice this issue? I ran it by our Service manager he looked for information about this and all he found we notes from GM about shifting from Park too quickly being the possible cause. I made a video this morning and showed it to him and now he thinks it might need an update. So I will probably put it in service after Christmas and let them check it out. I have 2 other Chevys a 19 Trax and 19 Equinox and none of them, or any other GM car I have had in the last 5 or 6 years since the Grid Lines were incorporated to the Back Up Camera have had this issue. This seems to be a cold weather issue as I did not experience this problem in September, or early October at all. My Bolt now has 5600 miles on it so it does not sit around a lot.

I have a new (purchased 1-24-2021) 2020 Bolt and just about 100 miles. My car just started doing the same thing, no gridlines on the screen. It has the option up at the bottom to switch them on and off but doesn't seem to care which setting. I guess it will go back to the dealer and see if they can fix it.

i don't know if it will help, but you can press "home" + "FF" to reset the system. Kinda like CTL-ALT-DEL on a computer.
Or, as a last resort, disconnect (use a 10mm wrench) the negative 12V battery lead for 10-15 seconds. This resets the computer.

I have a 2023 Bolt (covered 34,500 miles). Just today the reverse guidance grids did not show up on the rearview. It never happened before.
So, when I put my car in reverse, a small box diagram showed on the bottom left of the rearview. I gently touched the top right portion of the box (within the box), and the guidance grids came on. When I touched the same spot again, the guidance grids went off. By mistake, I must have touched it after putting the car in reverse. An easy solution.

Something that comes to mind is that a loss of signal from the steering angle sensor might cause the grid lines not to display. That is a qualified maybe because other systems such as StabiliTrack probably also need steering angle data and they would likely set a diagnostic code and warning light. It is still worth doing a check-out with a higher end scan tool such as an Autel which can do a deep inspection of the various ECUs.

The other possibility is that a firmware update did not execute properly. I have a 2017 Bolt, and a few weeks after battery recall replacement, the car started popping up a box every few minutes over top of anything on the infotainment screen saying that the Bluetooth had been disconnected regardless of whether anything was actually using Bluetooth. It was driving me crazy. I took the car back to the dealer who had done the battery swap. They re-flashed the software and that fixed the problem.

As other people mentioned, holding down Home and Fast Forward next to the volume control for about 10 seconds will reboot the infotainment computer. The screen should go black for a few seconds, then display the Bolt logo while it reboots.
