How to upgrade my GMC Yukon 2015 software without OnStar (outside of US)

I purchased recently a GMC Yukon XL from 2015 and the software version is rather outdated.

 

I do not have OnStar as this was stopped in Europe several years ago.

 

Is there a way to do the latest update offline, using a USB stick or eventually a diagnostics tool?

GM Dealer or shop that has access to GM Service Programming.  Something of that vintage there really won't be much in the form of updates anyway.

 

What do you "think" you are missing that an update would fix?

Hi @newdude, thank you for following up. I do not have a choice going to a dealer as there is no GMC dealer in Europe, unfortunately. GMC trucks are very rare here so I am not able to find a shop that does those neither.

 

On the other hand, I do have VX DIAG - VCX Nano that is meant to do many things. Do you know if I could do the upgrade using it?

 

Regarding why I would like to do the update, it started from the fact that I am not able to browse mp4 movies on my USB stick using the central console screen. Asked a question about, I was told that this is probably due to the fact I have an outdated software version and I need to update it. In addition, I do not have the option to connect the truck to my phone wifi hotspot nor I can download any new application.

 

The current software versions I have are shown on the attached picture, what do you think, should I update those?

Movies on the front radio screen weren't a feature on any of the factory programming.   That is done via HMI unlocking through aftermarket sources.

 

One place is WAMS - GM HMI Full Feature Unlock Service - White Automotive & Media Services (whiteautoandmedia.com)

 

Here is another place - GM HMI, Radio Unlock & In-Motion Services | GM Programming (gm-navigation.com)

 

As for if the software you show is up to date, there isn't a way of checking that without being plugged into GM SPS (service programming system).

Thanks @newdude. I was probably not clear. I am not willing to watch movies on the front screen in motion, but being able to browse the movies I have on the USB stick. I can change movies with the forward and backward buttons but cannot see a list of files / movies I have on the USB.

 

In which concerns the SPS, I have in my possesion the VX Diag - VX Nano tool for GM. I was trying today to purchase a 24h Delko SPS2 service but somehow I am not able to do the connection with my VX Nano diag tool.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
