It could be this.  I think it is some sort of communications module because it has an IMEI number printed on it.

Look up that number online and see what pops up.

An imei number is for a cellular device.

Pull it out and throw it in the trash.

I think the dealer is lying or it is a dealer trade and they did not know. It sure ain't factory. OP, what dealer is listed on the window sticker? Is it where you bought it?

Do you have a finance company, maybe a small one linked to in house dealership financing. Some of the second chance and low qualified finance companies have contracts with Stealer ships to put tracking devices that connect similar to what your describing on new Even new vehicles . it used to be only used ones. If your dealer is trying to play dumb and not requesting you to bring it in immediately  i would be thinking its kind of device.. Just do not be one day late on a payment if it is..  

 

Just a guess i know someone who works at a second chance finance dept thru a new car dealer.  

 

 

I paid cash for the truck, so I'm not sure why they would install such a device.  I will take it to the dealer so they can see it directly.

If you bought it new directly from the dealer and they do not know what it is then there would be some serious ‘splaining to do by the dealer and General Manager.

This is extremely interesting. I would want to know why there's a device designed to broadcast my truck's vital information to a cellular / internet network ...

 

Is this the way new vehicles are going? We know it's the way government is going ... ?

The truck likely has onstar and they/GM get all their data through that.

Nothing to do with On Star in the OBD port. Usually anything plugged into it interferes with communication between the truck and "big brother".

I agree, but was wondering if any other device used IMEI numbers also.  

Are there a lot of thefts in your area? If so the lot is trying to track down their trucks after they are stolen.

 

Would check with the dealer to see how it is installed, saw some horrifying videos of cars with their dash ripped apart as they try to hide the device and the battery back up when putting them in.

Not till I figure out what it does.  I disconnected it and On Star still worked.  I need to make sure it is not part of a safety mechanism.  THis truck has so many bells and whistles on it, I have not discovered them all.  I wouldn't be surprised if this thing makes coffee.

Can you post pics of the device and install?

I'm betting it's a wireless programming interface they use in the factory on the assembly line and someone forgot to pull it.

      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
