Check Engine Light

My check engine light is on. 2013 F150, 5.0, 43k miles. Oreilly scan says P2610. PCM has detected a malfunction in its internal engine off timer processor.
Any help here?

Maybe replace the PCM power relay and clear the code and see if it comes back.

By any chance has anyone been jacking with the radio and or it's wiring? Electrical interference is an all too real happenstance, more so than anything oem.

Nothing has been done or added. It had an issue with the cooling fan running on high. Replaced the relay and cured the issue. it was odd because just the drivers side fan ran on high. after replacing the relay both fans run on low speed? Also got a alert on screen needed oil changed, only had 1000 miles on oil but was over 12 months.I changed the oil and reset oil monitor.I have unhooked the battery for a few minutes and the check engine light goes off. But comes back on 1/2 hour later. Is it wrong to clear it like that?

Cooling system anomalies are one of the listed possible causes.
