New to the forums, sorry if this is a redundant post. I've read through probably 100 power mirror threads all around the interwebs, but it's been difficult to track down a straight answer to my question/situation. Hopefully it's a simple yes/no, and we can archive this thing for future reference.

 

My truck has FOB DL3 mirrors from the factory, but does not have the memory seat option.

 

What do I need to enable aut-tilt in the DIC?

A) Have a dealer or somebody with a Tech II/GDSD2 flash the BCM to enable "memory seat" (A45?) option

B) New wire harnesses

C) Both

D) Something else??

For the sake of successful searches:

LH 23180074 & RH 23499472, LH 23171577 & RH 23171579, 15906881

Contact pgamboa. He has done TONS of work on the various mirrors and has most of the schematics figured out. If you send him your info and some pictures of the connectors he can probably help you out. He also has quite a few threads on here about the different mirrors.

Pgamboa can help with the dl8 to dl3 mirrors, but not this. It is all controlled by the bcm and last time I heard, it cannot be added to the software. Are you sure there's not a setting on the info screen if you already have the DL3's?

This is right... I have no knowledge of the requirements for auto tilt as this is a feature in the cluster.

 

In my conversations with GTPrix, at this time, it seems like there is more to it and that might be hardware dependent (Seat Memory Module and having A45). The OP is one of the few that has DL3 Mirrors Minus the A45 Seat Memory option. I find it odd on one the harness part #s though as I have 23171579 as a DL8 Harness. So I am a little confused on how the DL3 is fully functional (lighting portions that is) as is.

 

I wish I had more information for ya. But anything with the cluster options (auto tilt reverse, FOB Mirror Fold In/Out) are outside of my research... at the moment... :)

Thanks guys.

 

To be clear, those are not MY part numbers - they're just PNs I pulled out of other threads with vague thread titles.

 

My truck is a 2014 Sierra All Terrain. I think I have DL3? My mirrors do have power fold and turn signals, but there is no option for auto tilt in the US. I also haven't been able to find a memory seat button anywhere

Your memory seat buttons would be on the trim panel, right above the handle to open the door if you had the memory seats.

Look in your glove box RPO list. If you don't se A45 listed, your don't have Seat Memory. If the option for reverse tilt is not in your settings options in the radio, you don't have it. This is fondupot's video showing that. That feature might be dependent on the Seat Memory Module which doesn't sound like you have.

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
