have Prius 2011, 3rd Gen, driven for 1,67,000/ Kim's. Last night, abs, Hand brake and traction light came ON when I was parked outside a shopping mall with engine running. I tried to reset the lights by removing battery terminals but not successful. Torque scan does not read any fault code. I have noticed that brake pedal has gone hard and ABS motor is continuously working with small pauses. Can any body help me out. Regards
