Update to new code

I found out the other day that the newest version of code prevents Night Panel from working, or allowing you to use OpenSID.

I think the only difference is the 348 message, bit 2, being a 1 instead of a 5. I think when it's a 1, that is the highest priority, as if Night Panel were on (no gauges lit) & your coolant temp got too hot, your SID would light up & tell you. So I think it's probably better to leave this message bit higher & just deal with flashing SID txt for a few seconds.
