    I have a 2003 Prius, I had an accident and after it was fixed the check engine light started coming on. It would go off after a couple of days. The first time I took it to Autozone and the codes were P3150 & P3130, but the next day the check engine light went off. A couple of days later the light came back on....went back off....next week it stalled on the highway, but it started back up, now the codes it's reading are P1636 and P3002. It still starts up and will drive, but I'm afraid to drive it. Anyone have any ideas?

    Hi pat883,

    I 've checked the Repair Manual and it seems there is no such code P3150. Perhaps it was P3105? Anyway, the other 2 codes P1636 and P3002 have something to do with communication errors and it is usually caused by weak 12V Aux. Battery.

    Replacing the Aux. Battery may not fix the problem as I think the root cause could be due to the Inverter Cooling System Malfunction (P3130). Overheating in the cooling system may have caused the DC-DC Converter not charging the Aux. Battery. Please check the fluid level of the Inverter Coolant and whether there are turbulences during operation.
