Is it bad to take the car for a long trip from Los Angeles to las Vegas with that code on. Or should I take to the dealer before I go. Thank you

You should have the dealer check it first. The code has to do with the engine coolant system, and if the coolant system is not working properly, it may overheat the engine.

My two codes are P261F-01 & 02, I think a mouse or rat damaged some wiring to the battery. I looked really good and couldn’t find any damage.
Is the car safe to drive until my appt in 5 days?-
Those codes—P261F-01 and -02—point to issues with the auxiliary coolant pump, like performance or electrical faults. If a rodent chewed wiring near the battery, that could explain it, especially if any wiring harness runs along that area.
If the engine isn’t overheating and you’re not getting any temperature warnings or loss of coolant, it’s probably safe to drive short distances until your appointment. Just keep an eye on the temp gauge and avoid heavy traffic or long uphill drives where the engine may run hotter.
Also, check for any chewed plastic wire coverings or droppings around the battery or fuse box again—they can be easy to miss. Let the shop know you suspect rodent damage—they’ll know what to look for.

Thank you friend. The light went off after I put coolant in it. May be coincidence. I will still get a diagnosis and oil change at the dealer in five days.

I have this code coming on, and noticed my fluid was low. I'm not seeing any signs of leaks in the compartment, but I may not be seeing it. Also, I can't find a replacement Aux Pump for my 2009 STS 3.6...does it even have one?
