Back Up Lights Stay On

Truck in question is an 07 yukon xl. Intermittently, the back up lights will stay on. Engine can be running, in park, drive etc. More often, it happens when parking/locking the truck. Lock with the key fob, back up lights stay on. Has run the battery dead twice, now my wife checks that they go out before she walks away. When they do stay on, you can often get them to shut off by repeatedly unlocking and re-locking the truck with the key fob. Occasionally, if that doesn't work, starting the truck and shutting off gets them off. Once, nothing would work, so i disconnected the battery for a min or so, and then when i reconnected, they were off.

 

Truck is under warranty, unfortunately, dealer 'can not duplicate' problem, and is unwilling to do anything without seeing the issue.

Any help appreciated, first american car in quite a while, and looking like the last one too.

Sounds like there's a bad connection in the switch. Get the schematics and look them over. If that loses ya, then just start at the switch and check everything out.

Then it's clear the dealer has no interest and perhaps you should instead find someone else. Dealers aren't gods of any sort, and if you don't like the way they do their work, find someone else.

the yukon xl replaced a land cruiser that was darn near perfect, and trouble free(for 170k miles), but we wanted the extra space behind the third row that the toyota didn't have.

 

But yeah, otherwise you're right on the money, a car that leaves my wife stranded is worthless imho.

 

 

And yes, this dealer obviously doesn't care much about customer service. Unfortunately, the other gmc dealership in the area closed down.

So, the back-up lights left her stranded? :cheers::fume:

Grab a video camera and take a video when it happens to show the dealer when it happens next. Also try to notice if there is any sequence of actions that are similar when the problem occurs.

 

It sounds like there is an issue with the BCM and the timer for controlling the lights when locking and unlocking the doors via the fob.

That's funny, just today I saw a newer model Sienna driving down the road, it's back-up lights stuck on as well, looked pretty retarded :lol::lol::lol: but then again most of Toyota's vehicles (not all, just most) look retarded.

Do you have an aftermarket nav system or mod wired into it installed?

 

I only ask because I had a similar complaint that turned out to be from that. Normaly leaves comm codes a tech can see though.

Also, easyest thing to do is swap the relay(underhood fuse block) for a known good one, pretty easy and you can do it yourself... See if it was sticking. I have had that happen before too, sometimes on newer vehicles but mostly on older ones. If its not that your looking more toward it being a BCM problem.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
