Service Performed Codes

2025 Yukon Denali 3.0l Duramax

Is anyone aware of a decoder sheet for the Dealer "Service Performed" codes, warranty or otherwise?

I'm guessing there are not unique to every dealer.

Just Google something like "gm service performed code 2810335"

2810335 is Reprogram Labor Code: 2810325 (see https://static.nhtsa.gov/odi/tsbs/2018/MC-10143758-9999.pdf for example)
2810215 is labor to reprogram BCM (see https://dot.report/bulletins/10134541 for example)

Won't your service advisor tell you?

Thank you Fless. My internet searches were not returning useful results. I'm using DuckDuckGo.

As far as my Service Advisor's explanations, they are usually lacking in detail. I want to trust but am inclined to verify.

Are these "Updates" that the vehicle needs or in response to having a certain condition?

Stbentoak,

These were the most recent updates to address ongoing symptoms of the infotainment screen becoming unresponsive, intermittent CEL, steering wheel buttons unresponsive, key fob recognition for starting intermittent, and a host of other seeming unrelated things not working as expected.

It's been in the shop 8 times in as many weeks for basically the same issues. Kind of like Whack-A-Mole.

It seems that when they do updates for, "intermittent CEL", all they do is go in to that system and make it less sensitive.
Meaning the fault has to happen more times than before, to turn on CEL.

That deserves a "standing ovation".
