So I have to move my Prius into my garage so that my other car parked in the street can be parked in the driveway. It's 8F outside and when I started my Prius nothing happens.. it's not going "READY" mode so I can't move it. Tried several times and depressing hard the brake pedal (thinking that it might be bad) but no luck. I see all the lights up in the dashboard light but READY isn't lit. Voltage when turn is 13.8v on my cigarette lighter plug (it has voltmeter built in) I made it to turn on when I don't press on the brake and turn the start button on twice and when all the lights are on I press the brake pedal and press the start button again and it suddenly went to READY and engine started running.. Any experience similar with this cold weather? this is the 1st time I encounter this on my hybrid.
That's the voltage from the DC to DC converter that's powered by High Voltage battery and used to run the vehicles 12v sytems as well as charge the 12v battery because car is in ready mode. It can go up to 14.1v.
With temperatures that cold you're gonna have glitches if your 12v is weak, especially if there's moisture in the vehicle from the usual Gen2 leaks. What's more the hybrid battery ECU dials back the packs available discharge and charge abiliity in temperatures that cold. In other words, report back when temperatures are above freezing if you still have issues, but suspect the symptoms will go away once weather warms.
