    I change a cell from the hv battery and the car did not start. It came up with c2312, saying there is an issue in the park mechanism and I should park the car on level surface and I should use the parking brake. How can I resolve this? The car won't start.

    Mine's done this while driving like at the top of my street and I didn't pull a code. As I was driving at night to boot . I pulled over and opened the door closed the door cycle through the power button the car restarted and I drove it right back to the house and got in the sienna van. This is when I had just gotten the 09 and it seen the red triangle once and then right after this I replaced the pump for the inverter and then everything was good until the battery went bad about a month and a half ago that was replaced everything good

    SM-A715F ?

    What is the voltage reading at the 12V battery when the car is in ON mode? (all dash warning lights on but not in ready). Your code might be caused by the 12V battery being weak or low on charge. Check your 12V then charge or replace it if necessary.

    make sure you have a healthy 12 volt battery, and then follow the troubleshooting tree at techinfo.toyota.com
