I bought a 2008 about 7 months ago and have had no trouble with it until yesterday. The "maintenance required" light's been on for about a week as I haven't had a chance to change the oil yet. I swung by an auto parts place to pull the codes, just to make sure it wasn't indicating a real problem. I started the car and had it "ready" when they plugged it in and got no codes. I shut it off, went in, and got all the stuff I needed for the oil change. Then I drove off and the first time I tried to stop it seemed as if the re-gen brakes were not working, it was harder to stop and the pressure was not linear (even more than usual). I didn't notice till then that the E Brake light was on, the (!) light was on, the ABS light was on, and so was the VSC. I drove it home. Pulled the positive terminal off the battery and let it sit for a while. Upon starting it again, all lights were still on. Brake res is full so I'm not too worried about the hydraulic brakes. After reading through as many threads on here as I could find, I jumped the 4 and 13 terminals in the OBD port and pulled these codes (!) - 48 66 95 ABS - 42 VSC - 45 and even a 41 from the tire pressure warning Where can I look these up? After this I tried to reset by pushing the brake 8 times after turning it off and on. Lights are still on. I haven't had a chance to check the coolant pump. Help me with the next step if you can, thanks! Kit
1. Check the inverter coolant reservoir for fluid turbulence when the Prius is READY. If you do not see this, the inverter coolant pump (subject of a recall) has failed. 2. Check the 12V battery by measuring voltage across the battery terminals when the car is IG-OFF and has rested overnight. If lower than 12.5V, charge the battery overnight. If the battery voltage does not substantially improve after allowing a resting period for the surface charge to dissipate, replace the battery. 3. If 1 and 2 do not help, seek professional assistance. The blink codes that you retrieved do not match up with the repair manual docs I have - except that ((!)) 95 points to a failed skid control ECU, which is not something that you want to act upon without further confirmation.
