Hey everyone,

 

A while ago I posted a question about upgrading my 2008 Sierra SLE with a DIC switch that is supposed to allow me to view the full capabilities of the computer (Fuel mileage, Tire pressure, Engine mode, etc...).

 

Here is the link to my origional post:

 

http://www.gm-trucks.com/forums/index.php?...83644&hl=V4

 

I called my dealer and they have the DIC switch, however, when I explained to them what I intended to the service guy told me that he never heard of this upgrade being done and he was pretty sure that it couldn't be done.

 

???

 

Daddy's thread explained the procedure on a 2007 SLE so I was wondering if anyone attempted the upgrade on a 2008? I know there's probably no difference between the 2007 and the 2008... I'm just wondering.

 

Billdog350 also mentioned in my thread that he did a RPO code upgrade before installing the DIC. Does this need to be done in order for the DIC to work? If that's the case can someone post the procedure on how to do the RPO upgrade?

 

Thanks!

Here's the very last post in my thread and Mark has a 2008. It's plug-and-play. Just buy it and plug it in, you'll be fine. Not one person who has tried this has not had it work.

 

EDIT: BTW, Billdog350 has a GMT800, not a GMT900 so disregard what he said completely.

Hey, did you have any trouble taking your old panel off? I picked at mine to see if it would come off easy with no luck. I'm proabbly having a dumb phase and not doing it properly. :happysad:

Just carefully yet firmly pull it off. Start in a corner and work your way around. I was nervous at first too but, it is very easy. As to the switch being plug and play, don't worry it is. I asked the dealer too at first and they insisted that the wiring was not there. I ordered mine online and guess what? Daddy is right, and my DIC works like a charm. Just go ahead and do it!

I keep seeing all these threads regarding a DIC upgrade and I'm left wondering what would this give me that I don't already have?

I mean, I can already toggle through and see my Fuel mileage, Tire pressure, Engine mode, etc... as it is now. I have a 2008 Sierra SLE

If you already have the set of four buttons shown in this picture then you already have the advanced DIC. This unit will allow for you to change things such as entry and exit lighting, chime level, auto locking/unlocking and will also display other info such as timers, hour meters, fuel used, etc.

I did mine after Daddy did his. It took about 3 minutes and works like a charm.

 

Go for it.

 

Why is there always an idiot at the dealership whose only job is to tell people that this shit won't work? Frikkin Einsteins!

Because they don't know s**t, every time I go to my dealer and ask the service department about some accessories install I get frustrated, they don't even know about the stuff that GM offers on the accessory catalog, I feel like I'm in a Ford dealer.. :happysad: it's unbeleivable...and the part department sucks too, bad attitude and no interest on selling.

I don't understand why the DIC switch isn't standard on the SLE. It's not overly expensive. The switch is only $45.

 

It's stupid to pay out more money for the plastic molding. It cost's more than the switch!

 

I ordered mine today. Thank you all for your input!

The hardest part of the install for me was releasing the headlight switch from the old panel...the clips were tight. I love the DIC upgrade...the additional features are nice and it's a low cost mod. The only thing I'm not able to do with my DIC panel is access the TPMS relearn mode...I still have to use the keyless entry remote... :happysad:

That's odd because I can access the TPMS relearn just fine.

Definitely odd, but I went through every menu of each of the 4 buttons several times and it wasn't there. I held down the buttons on the key fob and, voila, it worked.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
