Is there any way to get the daytime running lights to go off when you put the vehicle in park? My 05 silveraldo did this but it seems that the ones on my Tahoe stay on all the time during the day. Is there a way to reprogram these to only come on when you shift out of park?

From 2007 Tahoe Manual:

 

The DRL system will come on when the following conditions are met:

 

 

• The ignition is on.

 

 

• The exterior lamps control is in AUTO.

 

 

• The transmission is not in PARK (P).

 

• The light sensor determines it is daytime.

 

If you Tahoe lamps are always on (including park, get your vehicle to the dealership, may be the BCM that needs updating)

what is a BCM? My 08 tahoe has what i believe to be an issue. the dashboard (cluster) lights will not turn off except at night. in other words i can not turn off the light to the cluster except at night. i can not even lowere the intensity. they showed me another 08 and it worked the same way..

BCM= Body Control Module, controls alot of the stuff that is body related (not engine and transmission) such as mirrors, memory settings, communications between various sensors, lighting control (not just flipping a switch anymore), radio/navigation control etc. I can look around for any tsbs and see if there are any solutions, my 2006 Silverado's DRLs turn on only when it is daylight and turn off and headlights turn on automatically (as well as the cluster), but I have not heard of the cluster lighting up unless the parking/headlights were on.

spoke with my local service manager and one of the techs, they have seen the drl's remain on in park have heard of the cluster remaining on when the headlights/parking lights are off, both the service manager and tech said that reflashing the BCM should take care of this problem. Take your truck in for the service visit for the DRLs. As for the cluster remaining on, I would first try to turn down the instrument panel brightness with the dial:

J: Dome Lamp Override Button/Instrument Panel Brightness Control

 

If that does not work, take it back in and insist on a solution. Ask to speak with the service manager, ask if this was a change, and where it is stated in the owner's manual (I did not find anything about this in the 2008 Tahoe's owner's manual)

turning down the intensity control has no affect. i was using the car yesterday and turnedoff the DRL. when it got dark enough to need lights the dash lights turned off too. pretty funny

Your cluster lights stay on all the time? I wish mine did..on my 2007 Yukon Denali with the dark colors of the backing and the dash itself, its hard to read the gauges during the day...one you can't even see!.Maybe thats why they are on all the time now, alot of complaints. Iam going to ask my dealer to make mine stay on all the time.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      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. 😉
