Lost camera guidelines front and rear

2022LiftedRST · April 3

Hello all, I am wondering if anyone here can help with a fix for my issue. I have spent some time googling over the last year or so as this has been an issue on and off, it seems this issue happens across any type of GM Vehicle.

my lines have gone which tell me where I’m going when I park. The screen displays the camera just fine, but there is a blue egg time in the top left corner and the button on the bottom right that toggles the lines view on and off is greyed out.

this has been happening for more or less the whole time since I got this refreshed 2022 in 2022 however recently the lines went and never came back, usually it fixes itself.

took it to a dealer and they didn’t help, simple answer was to blame it on my lift kit. They ignored the fact that it has been working for 90% of the time, It would just glitch once in a while, not often… but this time it’s not fixed itself

I have a GM Case open too, but it’s just hard work…

Any guidance would be greatly appreciated.

With the GM case, AND the dealership, be respectful and keep asking for 'help'. If they want to push back on the lift kit, and they likely will, ask if they can share any details as to how/why it would interfere. Explain that you want to know the details so you can discuss with the kit manufacturer to get their help as well.

Dealerships like to throw blame around but don't like to have to provide the details to justify their statements. The entire reason they don't want to cover it under warranty is because they want to charge YOU for the work (GM doesn't want to pay if they don't have to, and the dealership makes more profit on non-warranty work).

Just don't argue with them or let things get emotional. Stick to facts, remain calm, and keep expressing things in terms of "I need your help here".

Thank you for the reply! Attached here is the summary from the dealer. Basically I read this as, because I had the park assist retro fitted (chip shortage when I ordered the truck) they then had to recalibrate everything, which is why the lines don’t work.

the point which is being ignored is 1) this lines issue first happened 2 years ago, the park assist was installed in November 2023. The lines have continued to work 90% of the time until last week. This is why I think they are wrong, and it’s also noting to do with the lift.

they mention a hard error in the system preventing the lines from displaying, which ‘cannot’ be cleared…

doesn’t add up to me! I’m wondering if they could just refresh? Recalibrate? Reboot the modules or something … they seemed unwilling to try, and told me I was lucky the camera even works with the truck this high up…

Ugh... Messy.

- Do you have any work orders for the lines disappearing PRIOR to Park Assist being added?

- PRIOR to the lift being installed?

Anything you can provide that shows that the problem occurred before anyone touched anything would possibly help you here.

They told you there's an error but the work order shown implies it's a "setting." Terminology matters... settings have configurable options, errors indicate problems / failures. Which is it?

It seems that the tech is acknowledging that installing the lift made no actual changes to the camera system. Once the Park Assist was installed, however, they had to re-calibrate the camera to account for the changed height of the truck. Why would raising the truck and adjusting the camera angle turn that feature off? And, can you PROVE that it worked after the Park Assist was installed at any point?

Dealership Service Writers are useless for discussing this stuff - they spew all kinds of bullshit that I swear they make up on the spot and clearly have absolutely no clue what they're talking about. The Service Manager is likely just as useless (the one at the dealership where I bought my truck tried arguing specific repair items with me claiming that GM was "never" going to address them yet I not only had them addressed, but had them addressed at -that- dealership).

Speaking to the Shop Foreman may get you some details, and the actual Tech as well. You could request through GM Customer Assistance to speak with either the Field Tech (or any field tech) or the District Manager that covers that dealership to better understand the details and the options. Anything that a Field Tech offers up is very likely backed by documented details that they could provide to you.

Unfortunately I never had any previous work orders for this - it was never something that could be recreated! It would happen one day, then seconds later go back into reverse and it would be fine again for months.

all of the explanation about the park assist was kinda pointless because, it happened on and off before, and on and off after, just for now, it seems to be off and not back on!

the fact it’s all over other forums makes me wonder what the issue really is!

it even says on the attached Cadillac bulletin ‘may be caused by a software anomaly’

just needs a ctrl+alt+delete and a reboot!!

The dealership has claimed that there's an error that "can't be cleared" and that would mean it will never work. So, all you need now is for it to work... Once... When you can get video of it working on your phone. Be sure to add commentary as to the time and date, and capture the mileage on your truck in the video. This would all potentially negate the "it will never work again" claim of the dealership.

As an aside... There's been a MASSIVE problem with GM's OTA updates for their trucks. I bought my truck in late October, there was an OTA update, and shortly after I started having weird error codes showing up and setting the Check Engine Light. The dealership dismissed it as "no code" (and they don't know how to troubleshoot without a code or a TSB that explicitly calls out the exact issue) and gave the truck back. On the way home, it "blew up" my dash with every error code known to mankind, reduced power, etc. They had to get TAC involved for very detailed troubleshooting (I took the truck back to them -immediately-) and determined that the Gateway Communication module had a corruption and needed to be re-flashed.

@2022LiftedRST Did you get any resolution to this? The dealer installed my leveling kit today and I noticed the same thing - no guidelines, disabled button for them, and the hourglass. Going to call tomorrow and see if they messed with any calibration, I can’t imagine that it can detect that it’s sitting a few inches higher. It’s a pickup, loading the bed or towing could just as easily affect its angle!

Or the setting got changed.

The are several selections available.

One of the options that can be selected is 'no guidance lines'

I don't know which one is the default.

This button on the far right that’s now disabled? Or is there some other system setting I haven’t found yet?

Hello!

I do indeed have an update!

a few weeks ago I had the front of the truck lowered back down a bit to stop a vibration I had, and the camera lines came back and have worked as normal for 95% of the time since

looks like the dealer was right! The truck was too high. I was about 12” lift on the front. I switched to adjustable struts and the shop I go to recons they lowered it back down 2-3 inches or so.

sometimes my lines disappear for a day or so, but I’m guessing that’s due to the fact I’m still around a 9” lift on 37s so that must be close to the limit for the camera knowing where it is.
