I'd just get the BCM updated until the bulbs come in. The update alone will send more volts to the stock bulbs which has to help a little. Also get the radio update for reception...it helps.

 

I'm about to call in my headlight update with reference numbers, are their reference numbers for the radio reception update?

 

Thanks!

Drove around last night with my newly improved headlights. I have to say it is a drastic improvement. Way better. The only thing is I need to aim my lights down a bit since I added my Bilstein Level. Not much, just a tad.

Any chance you could check the voltage output at the bulb connector?

 

Curious to see what it is after the BCM update.

My truck was built on 2-3-15 in Mexico. According to the TSB, I should already have the upgrade. Pulled my headlight bulbs today and they are Phillips not Vosla. Went to the dealer and he can't explain it. He tried to order the Vosla bulbs but GM said the bulbs are non-existent. He thinks that the BCM was upgraded but can't explain why it came with the Phillips bulbs. Any ideas?

Had my truck in to the dealership to verify that I fall under the warranty today. Dealer says they will perform the fix as soon as the parts become available and right now claims there isn't a spare bulb in the entire continental US.

Just got off the phone with me dealer's Service Manager. Taking the truck in next Friday for the IntelliLink update and leaving it for the day (supposedly a lengthy update this time). He has not been able to order the bulbs as of yet as the system won't let them (no availability). He will try again on the off chance that he can get them for next Friday.

 

He mentioned to me that the doc has been revised again and is now at PIT5374B.

So then it appears the TSB isn't worth the paper it's printed on. My truck was built 2 1/2 weeks after they should have been installing the Vosla bulbs, yet mine came with Phillips.

Sorry, after re-reading and re-reading the TSB it appears that the upgrade to the BCM was done. If I go to the dealership and bitch, they are to replace both bulbs. Now I get it. I gots to get me some new bulbs. But according to GM, the bulbs can't be had anywhere.

Someone will need to find a copy of the updated number for future readers of this post Id imagine, or anyone that has yet to get an order in. Dealer told me just now bulbs are shown as out of stock as well.

For what it's worth, it took 2 weeks for my dealer to get the new bulbs....they seem to be in short supply.

I have no issue waiting for the parts to come in. My dealer is saying he's not being allowed to even order the parts.

I dont have a multimeter or anything.

Probably because they are so severely back ordered.

No bulb shortage in Ontario Canada. I had mines done right away in Cambridge

Forgot to mention that my dealer ALSO told me today that the bulbs were apparently being sourced out of Vancouver. Seemed odd, but might be why the folks to the North seem to be getting this done so quickly.

      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.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.

      Chris 21 I appreciate your constructive response. !!  😉😉😉   The 6.6 is gas.  Correct me if I’m wrong but by recalibrating the speedo you’re correcting the shift points of the transmission on these trucks.?.

      That is a huge misconception.     Bigger does not always equal safer.  Modifying does not make it safer either, with exceptions.   Think of this.  Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.   37s and a lift?  Now you've affected your braking distances, handling and ride control.  You've raised your center of gravity higher.  Your front visibility is now obstructed more than stock, same for your rear.  Does it look cooler?  Yes.  Does it now work as good as it did from factory on road?  NO.       As for my mention of exceptions?  Say you had a sedan or crossover.  They typically come with all season tires.  If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle.  That is an actually improving modification.  My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size.  It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
