I recently bought a 2017 Sierra that came from Canada. I tried to turn off the lights to just the running lights and they wouldn't switch this morning. Pulled out the owner's manual and says right in there that you can only turn them off in park.

 

My question is: Anyone have a mod or work around to be able to switch to running lights when not in park?

We do a fair amount of camping and I always like to switch on running lights when pulling in at night.

Where do people ge this info? So the E85 station in Calgary is illegal... or Vancouver lol.  Come on.. the trucks here can run E85 just like anywhere else.  I can run e85 through my 2017 all day every

As I said many times already GM locks out the off function on their vehicles because it shuts off the DRLs on the US models which does not pass Canadian safety regulations.  Auto headlamps as of now a

Read this thread guess you’ll have to call Whites and see when they are going to do BCMs again?

Whites is not tuning BCM's and has no ET on when they will be again either.

He has a post on here about 3 weeks ago that he does program them all the time and what options are avail and what he has done so far. there is a picture of a new truck he got to test with for more features. I know it isn't no the wesite, well it is but only with the direct link. 

 

Gave it some thought and if you wanted to and are handy a simple relay on the headlight wire would do. Hardest part is removing the upper dash top trim to get to the light sensor. the bottom wire is the auto sense output. when that energizes the relay it powers the head lights. just a thought.

I contacted them last week and posted their reply in the other thread which is exactly what I said.  If you haven't spoke to them then you wouldn't know...

 

So from March 19th....

 

We are not taking any BCM work at this time. Please sign up for the notifications under that product on the website if you're interested in that service.

That's weird he posted a pic of his new truck and said for 14-18 the features available. Said they are working on more and to let them know what you want when you order.
I cant work the stupid search here but I remember it.
To bad.

What I find comical is the sign up for notifications thing.  I actually inquired for both my 2013 and my 2017... well you can sign up for notifications under the 2014+ but according to the site you can order a BCM for my 2013 no issue...even though you cannot and thus there is no notifications lol. Oh well.

I think I see what you are saying, just cut power/signal from the light sensor before it gets to the BCM?  Tricking BCM into thinking it is daylight.

On the schematic, it shows that some HVAC stuff would be affected as well?

GM has no availability for a reprogram.  Functioning as designed:

#PIT3219E: DRLs or Auto Headlights Will Not Disable with Headlamp Switch - (Apr 4, 2018)

 

Supersession Statement

This PI was superseded to update model years and condition. Please discard PIT3219D.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern

Some customer may state that the Daytime Running Lamps (DRL’s) or the auto headlamps will not shut off when using the daytime running lamp disable switch (Which is part of the headlamp switch). Vehicles that were built for Canada (RPO Z49) have different software that doesn’t allow the DRL’s or Auto headlamp to be shut off. Canada law prohibits disabling daytime running lamps (DRL’s) or auto headlamps.

Recommendation/Instructions

This is a normal operation of the vehicle and no repairs should be attempted.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

 

Gonna have to get a bit creative perhaps.  You could try to trick the light sensor to think its daylight all the time, but your DRL will still turn on in gear.

Seems like a lot of work just to get some headlights to turn off

 

I have a Canada truck and don't mind it at all

No I saying cut the headlight wire and use the light sensor wire to trigger the relay to then turn on the headlight wire. The bcm would have no idea it wasn't turning the headlights on. And the reset of the truck wouldn't know the difference.

It's a safety feature here. Your low beams and orange markers are always on. On my old 98, you used to be able to click the parking brake just slightly and they would shut off the low beams while driving, not anymore. You can't trick the daylight sensor, as the low beams are always on anyway so that would not work. I am stupid with wiring but I wonder if you can install an aux. switch in the main headlight harness? Or find a wrecked American truck and swap the BCM, but that may be a huge headache, I am sure there would be pinning and reprogramming involved?

      This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
