DIC remains blacked out since 8/15/2018 7:15 PM. Drove it for 20 miles, the display remained blacked out. Restarted the car a few times and recharged that evening, still it remained blacked out. This morning, after overnight charging, the DIC is still blacked out when starting the car.

Now I can't set it to charge at 12 Amps because the screen is blacked out... so am charging at a very low default rate of 8 Amps from our client's office....

Is there any other way to increase the charging rate to 12 Amps while the DIC is blacked out?

My service appointment is still on Monday and I go nuts without the DIC. I can still play music from the menus on the driver's side instrument panel and steering wheel buttons.

Actually, it defaults to 16A if the EVSE can supply it at 240V, such as in our garage where I have 240V 50A outlets. The OEM EVSE of the 2016-17 Volt can be plugged to the 240V and it will only provide 12A.


My client has only 120V at their place and it isn't a home location for my Volt, so location based charging to use 12A can't be set without the DIC screen.

You can use the MyChevrolet app to change the charge rate.

Select Vehicle Status
Edit Charge Limit

Hope this helps.

There's no option in editing Charge Limit on my MyChevrolet App :(

I can only find Charge Settings which only changes the Charge Mode

I got version 3.14.0 (131)

I tried this multiple times on the app and it NEVER worked. Apparently, Chevy figured out it never worked either and removed the option in a recent update.

OP, so when are you taking your Volt in for repair? Unless you've exceeded 36K miles you should still be under the B2B warranty.

It would be on Monday. I bought the extended Warranty that covers anything with wires or electronics and should be good for up to 60K miles.

Just to be clear, the manual distinguishes between the Driver Information Center (DIC) and the center stack display (or infotainment display).

Vehicle speed, estimated range, tire pressure, and oil life information is shown on the DIC, located in front of the driver.

Programmable charging is performed using the center stack display screen. The manual states "The Charge Limit Preference setting can be changed at any time while the center stack display is operable." I suspect this is the display that’s not working for you at the moment.

The myvolt.com website offers me the option of revising some charging preferences for my 2012 Volt (which came with a 12 amp default setting), but I’ve never attempted to do that via website (myvolt.com, mychevy.com), so don’t know if Charge Limit is one of the selectable items that can be done remotely via app or website.

Have you considered a possible blown fuse? F25 in the instrument panel fuse block, I note, is labeled "Display" and F26 "Infotainment." I also am curious about fuse F03 in the Engine Compartment Fuse Block, labeled "Non walk home" (???).

Tried pulling the main battery for a few minutes?

The only way I know how to do it blind is either to memorize button presses, or to use a device on the obd2 port to inject canbus commands. I made a raspberry pi that listens for Shifted to park and sends the "12v charging command".

Didn't know the DIC is the instrument panel, I thought it was the Display in Center (DIC) of the car! LOL! ;)

So it is called the Infotainment Center Console.

Anyway, I cancelled my appointment today. The Center Console Turned on this morning when it was scheduled to be in the dealer this 7 AM. Anything electronics related are like this. Takes a few days to get an appointment and then when it is appointment time, the problem takes care of itself! Always!

I think what happened in this incident is that we got into our hottest temperature of the year and I left my Volt to charge at a public charging station that has no shade, and I didn't open the windows slightly for hot air to escape. Practically the console was cooked. After a couple of days it returned.

Yesterday, after exposed in the sun while parked for a long time, when I used the car, the display was very dark again. It got to 104F outside temp. But after the cabin cooled off, the display console returned.
