Customer Question

We have a 2010 prius, 170 000KM. Last time we tried to start it, it would not...
All dash lights were opened and the ''READY'' would not appear.
Only the accessories mode would work. Battery was full we were able to play radio and open/close windows...
We unplugged the battery as we do for maintenance or else, and then the CHeck hybrid system appeared. The car would not start after that either...
Any clue?
JA: Does the engine turn over? How old is the battery?
Customer: no and battery is the original one
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: we hope to fix it ourselves... Maybe it is a sensor...but wich one. A few month ago we change the rear bearing containing the spead sensor wich was not working properly
JA: Anything else you think the mechanic should know?
Customer: nothing i'm aware . We only had this spead sensor issue, and bearings problem since we have the car. It was a really hot day...

Before we unplugged the battery, at first when the car would not start, we had ''triangle light'' flashing too.

12 V

Specification: And not all dash lights were on but almost.

Thanks, ***** ***** is the original 12 volt battery then I would recommend having it checked, if the voltage goes below 11.8 volts the radio and accessories may still work but the hybrid computers will not, it's very likely that the battery needs to be replaced/

Thanks, ***** ***** was not the problem. Problem was from a light cable that was squeezed so the brake signal would not pass between the brake and the car computer...
