Yaris hybrid won't start, have fully charger battery

Recommended Posts

Hi all. Am new here. I have a 2014 Hybrid Yaris. A week ago I'm pretty sure I left the headlights on for 2 whole days. Of course, my car was completely dead when i returned to it, no light, no central locking, nothing. I had a friend come with jumper cables. Nothing. The next day a mechanic came with jumper cables with a fully charged booster thingy. Nothing. Mechanic was baffled (disclaimer: was not a hybrid mechanic...). So, i removed the 12V Battery and charged it in my kitchen. When first plugged to charger it read 7.6V. It took 50 hours to get it to 14V. Although due to darkness i didnt install batt until next day, and it had then gone down to 12.7V. I install the Battery (on 12.7v) back in. Wahoo - there's lights in the dash, the central locking is working. Will the car start? No. Ready light will not come on. Tried everything, locking and unlocking car, fully pushing break peddle, every bit of advice in the manual....nothing works. Now the really annoying thing is it was booked to be truck-lifted to Toyota this morning to be seen, and due to Corona virus, our entire country was shut down last night (UK) and Toyota is now closed. Normal garages are operating, but not Toyota (for some strange reason). Normal garages don't seem to really know hybrids, so am reluctant to pay to get it lifted there. Any advice GREATLY appreciated. I have no breakdown cover. Car is very near my house but too far for an extension lead. Battery is definitely in nice and tight. Beware: i don't know the first thing about cars let alone hybrids so any language will need to be very much for dummies!!!! I've done all of the above with MASSES of help via telephone!! Mileage: 29,000

Have you tried using the spare key ? Do you hear the steering lock release ? If not foot on the brake hold the fob on top of the button till you hear it, then press and hold the button or press it twice

If the hybrid Battery is fully discharged - which it will be - none of its compex electronics controlling how the Battery is charged etc will work.

You WILL need someone with the specific charger who knows what they are doing - and has done it before - to recharge it.

If you get someone who does not know what they are doing - or who has not the correct equipment - there is a risk the Battery or electronic will be damaged. £1000s repair bills.

Hi, 

have you sorted your troubles yet.? If not you can visit this forum https://priuschat.com/forum/ and search in there for similar problems. Either model of Prius will be very similar to yours and might give you a light how and what to do. There are people that knows a lot of this cars out there, they fix their cars themselves. Just look at it and I am sure you will find something helpful. Good luck and please share with us how it is going. 👍

I have left a Yaris Hybrid for well over 2 months and the hybrid Battery never fell by more than 2 bars, the 12V Battery also held it's charge and the car started first attempt.

Does the screen showing the hybrid Battery charge still work ?

Do you hear any relays clicking when you power-on the car ?

Have a good look at all the fuses and give the relays a gentle tap.

Leaving the lights on will not drain the traction Battery the system has fail safes in place, the safety loop may have been pulled or disturbed tho meaning the contactors will not pull in

Welcome Elle :smile: 

 

Since you have no breakdown cover, I wonder if buying the Toyota breakdown cover (only £84 per year), then call them a day later - if they will come out and diagnose for you 🤔
