10 PCM P1258 H

I got a coolant overheat message on the way in to work this morning, so it is probably related to that. I still wanted to know what this code is just in case though.

Thanks in advance.

Thanks!

Any idea what it means when it says, 'DTC set immediately and MIL is turned on'?

I understand everything except, what is 'MIL'?

You might consider the wisdom of flushing and changing out the Dex-Cool if it got "very" hot.

Dex-Cool is great IMO, but it can be a potential problem if it's allowed to get really hot.

Ask your dealer.
