Help w/ p2610 code

I haven't started my car for months and all of a sudden I noticed my key fob would unlock the doors? So I opened manually and noticed the dash didn't light up or interior lights? As I placed the key fob into ignition, I noticed that the whole system glitched, and the clock was running in circles? Car started fine with no hesitation and runs smoothly. But now the check engine light came on and when I diagnostic with my code reader, a code p2610 came about?. Engine control module timer fault? Has anyone experience this? 07 model 104k miles.

computer been off for too long and lost dynamic obd data.

charge battery well, reset code and you should be good.

clock running circles is clock adjusting. this is normal as long it stops at some point lol.

glitching instrument cluster is also normal with low voltage. this is the most common way to fry your instrument cluster btw.

If your batteries are good (yes- both) code should clear automatically after several longer (more than 20-30 mins) drives

Yes, the auxiliary battery behind the rear passenger seat is discharged. You can have it tested at Autozone or another parts store to see if it needs replacement. If it needs to be replaced, it takes an H8 AGM battery, which can be had for under $150 at many stores. Autozone installed mine for no charge.

Your vehicle does not have aux battery in trunk, equipped with main battery in engine compartment and aux battery (backup for transmission lever) in dash see attachment.
