P0D5C error code

[jay-y]

My new Hummer threw a check engine light after just 24 hours!

I called OnStar, and they gave me a strange code: P0D5C. They said I needed to get it fixed right away.

Has anyone else had this experience?

How far is the closest GMC EV dealer to you? They should be able to check things out and update your system if necessary. My main problem is the distance to the dealerships.

How did you get the code? Also did a warning light come on?

The code is related to the coolant levels.

The code is related to the coolant levels.

It also could be the the AC refirgerant. But I guess it is not the case, considering it is winter.

I had this on one of my older evs and it was a simple top up, as it wasn't set right from the factory. IMPORTANT battery heating and cooling systems don't use the normal coolant make sure you dealer is the one topping it up if needed.
