Hi all, 

I put this in the Title Topic for your attention  - But its connected to the subject and thread below and my most recent coment on it.

Which Batt? The 12v or the hybrid?

 

  • Author

I havent changed the 12v batt. It was fine as far as I know before the car stopped. Batt only 2 years old. Although, it is now flat as the car has been sitting there for 4 months. Have trickle charged it a few times but has stopped holding charge now as gone below 7%. 

Wouldnt that have come up on the Diagnostics?

Would it have affected the Inverter or caused a P3125 -  Sub codes 495,496,497 and 484?

Is it worth buying a new battery first - I need a new one now anyway!

A bad 12v battery will stop the hybrid system from working- happened to me and the correct replacement is not cheap. It is a good starting point.
