Hi all,

 

Brand new member here. Hoping someone can help me with an issue I just had. Yesterday my infotainment screen went black and would not respond. I couldn't use radio, navigation, Apple CarPlay, or anything like that. The dashboard and HVAC were both unaffected. The backup camera did turn on, but it didn't have the steering guide lines and it was very fish-eyed.

 

This morning, my battery was completely dead. My charger/jumper unit said the battery level was at 0%. After about 20 minutes of charging, I was able to jump the truck and everything seems to be fixed, including the infotainment system.

 

Has anyone else experienced this? Know of a root cause, or how to make sure it doesn't happen again?

Thanks in advance for any help.

What year vehicle and how old is the battery (is it original)?

 

Sometimes the battery does not have enough to switch off all the relays (all the clicking and buzzing you  hear after turning off the vehicle and exiting it)

 

Check the alternator to ensure it is charging the battery when the vehicle is running.  If you have the oem supplied gauge it should show from 12 to 14 when the engine is running.

 

Have a battery shop or automotive shop perform a load test on the battery.. they can check the alternator as well.

I replaced my battery after 4 years at the dealer from a new purchase in 2020. These AGM batteries just don't die like the old lead acid. Need to be proactive with these AGM's in my opinion. 

 

The main reason I replied is I have had very intermittent infotainment screen malfunction issues. 

 

1. Test pattern on the screen with normal audio. 

2. No audio at all including the turn signals with normal screen display.

3. Black screen with normal audio. 

4. Normal screen with no audio from the radio only. Turn signal sound was normal. 

 

1 and 2 occurred about a year apart. 

3 and 4 occurred 1 week apart in fairly cold weather. 

 

After the truck sits for a time, all malfunctions appear to reset and screen and audio return to normal operation. 

All updates are complete that I checked and the dealer also verified. 

 

Thanks for any thoughts on this.

We have a 2020 Acadia with about 50k miles on it. It started showing codes randomly. I read them with my reader and saw stuff like,  Steering assist dimished , Low coolant temp. and a couple others. I saw similar problems in an Acadia forum. People were throwing parts at the problem with limited success. 

Anyway, to me, the common thread seemed like low voltage. I tested my battery and it showed normal range. I put a charger on the battery over night. The next day all of the codes went away. So I replaced the battery and the problem is solved. Low voltage in these new vehicles can do strange things.

 

Moral of the story. Don't overlook the battery.

Yes, knowing the year of the vehicle and the age of the battery would help.  I did some research when I replaced the OE battery in my 2020 Silverado a few months ago.  It was showing the classic signs of dying that the lead acid batteries would show, Andhra fortunately I have one of those NOCO jump packs in my truck at all times.  Apparently, the best battery in our sizes is made by ACDelco.  However, our trucks are equipped with a silver label battery.  I went with the gold label ACDelco battery because it provides higher CCA, etc.  If you have to replace the battery, this is the route I recommend going.  Btw, I got the battery from Rock Auto.

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release 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.

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

      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?
