I definitely haven't done enough research on this, so I'm confused about one thing:  How do the cruise control buttons function?  I had ASSumed that the cruise control buttons would use the same communications bus that the audio control buttons on the steering wheel would use, but apparently that's not the case.  

 

Do the cruise control buttons also use LIN, but go to a different LIN master controller than the audio control buttons?  Or are the cruise control buttons communicating directly on the CAN bus?

 

From what you guys are saying about having to switch to the expensive gauge cluster, I'm guessing that the gauge cluster is the LIN master controller for the audio control buttons, which would then send the commands out on the CAN bus for the audio system to digest.

 

Either way, I still plan on sniffing the CAN bus on my friends LT truck to see if audio control button codes can be observed there.

They operate separately,  so does the heated wheel. You need to run a wire from the cluster harness plug to the clock spring. Also need tho a better cluster if you have a custom.

 

 

Well, that wasn't the level of technical information that I was seeking.  :)  

 

Yes, I understand that you needed to run a wire from the cluster harness plug to the clock spring on the steering wheel in order to make the steering wheel audio controls work with the upgraded cluster that has been reprogrammed by White Automotive.

 

I was hoping to learn about how the audio control buttons differ from the cruise control buttons in terms of signal topology.

 

I'm guessing that the cruise control buttons and the audio control buttons are both LIN devices, but attached to different LIN controllers.

 

Since pin 9 on the clockspring controller seems to be connected to the LIN bus for the steering wheel audio controls, I'm hoping that I could create a standalone LIN to CAN translator device to read the steering wheel buttons from that pin 9, and send the correct corresponding CAN signals to the audio system (after somehow connecting to the CAN bus).  That way I would not need to purchase the instrument panel upgrade.

I did a few changes in the last few weeks, I picked up a set of gm new trailboss ranchos, trailboss cv shafts, 2.0 trailboss leveling kit , 2.5 rear blocks and xl9000 rear shocks.

 

Removing the icon stuff wasn't the original idea but the current setup rides pretty nice and it looks good. Yes it handled and felt more controlled with the icons but its pretty soft and smooth now.

The new truck looks good!  I have never heard of a TB not having the TB bed sticker.  Interesting.

 

I miss not having some features of the LT, but I liked the front end looks so much better on my Custom TB.  And the price difference was substantial....

 I do like the look of the front end of the Custom!  Also, I found a thread on taking the Trail Boss sticker off the bed.  I thought it was under the clear coat and couldn't be removed.  I was wrong. :)

The interior needed a few upgrades, I added a high country cluster from wams and a ltz steering wheel. Added a wire from the cluster connector to the clock spring ( harness dr) and now the stereo/phone wheel buttons work. Also changed the stereo bezel to match the steering wheel. 

 

I did the clazzio leather heated seat kit, they fit super nice and as you sit in em more they fit better as you can tighten them. This is when I 1st installed them.

Did you get the heat button to work on the steering wheel?

No, ran power to it and the switch doesn't light up and the wheel doesn't work....  sorry... its a shame since everything else works.

From the little bit of research that I did as seen here:

It appears that you'll need to connect the LIN Bus 19 line.  It needs to run from the X85 clockspring connector pin 10 (Circuit 4119 GN/BU size 0.35, LIN Bus 19) to K33 HVAC Control Module X2 pin 6.

      OCI, not when but why?

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.
