ICE comes on anyway

almost cat like.

 

On the Internet, nobody knows you're a cat, unless you slip up and include it in your username.

 

I wonder if Hefner would have approved?

I refuse to call the green outline car a chocolate bunny!!

Ghost car - Ok
Zombie green car - Ok
Spirit car - much better

maybe a leprechaun.

 

i hear you bro.

 

Which of course is the key to a long marriage.

and success as a diplomat...

 

How do you summon up the "visual engine monitor", oh wise Sage and soothsayer" ! I, mere mortal, do not possess this knowledge which I hope you might impart upon this most unworthy Peasant!
My Prime Beast is Advanced!

Long, but also successful. It could be long and miserable!

Love the pic you posted. Shows EV MODE with square outline clear as day.

Wife's previous 2012 PiP would turn the ICE on when it was below 40F and I got over approximately 32MPH. I could not figure out why and it irritated me greatly. I tried to just drive it and enjoy the ICE waste heat in the cabin. It infuriates me that your Prime is turning the ICE on and I'm committed to following and contributing to this thread until we get satisfactory answers.

Keep us informed of your ongoing trials with the ICE. When unexpected ICE on occurs safely take a picture of multi-information display again and the center head unit or take note the AC/Heat settings and any front/rear defrost usage. We may end up needing more data from an OBD reader that can check tractions battery temperature and individual cell health.

 

I needed to know this. Was it posted before?

Ok,

• 2.0 miles / 25 MPH ~= 4.8 minutes, round it up to 5 minutes
• 35-40 MPH < 41 MPH, the past critical speed for hybrid mode

We need to see if others can replicate this protocol, something difficult in Dixie because our winter is so short.

1. Does leaving the car parked, heater off, and READY for 5 minutes accomplish the 2 miles @25 mph?
2. Does leaving the car parked, heater on, and READY for 5 minutes accomplish the 2 miles @25 mph?
3. Does preconditioning the car for 5 minutes accomplish the 2 miles @25 mph?

Calm my friend:

Intermittent problems are the hardest to replicate and living in Dixie, 'cold soak' is not a trivial problem. There were three months of a "brake pause" problem with the Gen-3 that took a lot of effort to diagnose. About the time we figured out how to quantify and replicate the problem, Toyota came out with a brake software update that fixed (or greatly reduced) the frequency to unobservable.

More of a practice, I started at 6:40 AM, a few minutes after sun rise but still in the ridge shadow. The windshield was a layer of ice measuring 18F (-8C) (radiant cooling.) The sides and hood measure in the low 20sF (-5C). Inside, the temperatures were 28-34F (-2 to 1C).

I wasn't able to get the car into READY plugged in. I'll have to review how a Plus trim car can precondition. So I unplugged and left the car in 77F (25C), max fan, direction windshield and feet. The external air temperature sensor reported 37F (3C). Parked warm-up, 5 minutes, no engine. It looks like 5 minutes dropped SOC to 99%.

I then drove 0.3 miles under 25 mph to where I could get on a cross-town road. Maximum acceleration to speeds up to +60 mph, the car remained in square 'EV mode' and filled EV car icon. Total loop distance, 3.3 miles. I'll try again tomorrow without the driveway warm-up.
