P3110 and U0293 Simultaneously

Hi guys,

I have a cluster of symptoms with my 2004 and haven’t been able to find the right thread to help diagnose. I’m hoping for some guidance from anyone who may have encountered similar issues or can point me to a thread.

Scanned codes are 3110 and U0293
Symptoms:
· For several months, the clock keeps resetting
· Gas gauge has suddenly flashed E when full three times over past 3 weeks – resolved on restart.
· 2 days ago, neither FOB would work in morning – worked a few hours later.
· My wife drove 40 miles home from work without issue until she pulled into the driveway. She said it wouldn’t shut off for nearly five minutes and flashed the death triangle and “car symbol with exclamation point”. This was the hottest day of the year for us at 100+. The only thing I have checked thus far is inverter pump function (could see turbulence in reservoir).

I can get through moderate level repairs (Brake actuator replacement, refurbishment of the hybrid battery, combination meter repair, etc.) if I have a good video. I’m not great with these more complex electrical system diagnostics, though. It seems likely the two codes point to where to start, but I would love some guidance from a pro or someone who has encountered the same symptoms. Many thanks in advance.

 

Thank you for the heads-up on 12v - I hadn't even considered that. The 12v is fairly new, but I'll test in AM and check the leads. I would love for that to be the issue. I'll let you know and thank you again.
