    I have a 2006 Prius with 210k on it. And here are a few issues I have going on with it.

    • Intermittent ABS, BRAKE, VSC - Comes on. Turn car on and off, its gone.
    • Intermittent Right Side HID - On/off. Sometimes stays on all day, other times turns off.
    Here is the information I am getting from battery voltage. Regular voltage is 12.4+, under load its been at 11.5v
    also here are some codes I got for the ABS, VSC, Brake lights:

    • C0200 RIGHT WHEEL SPEED SENSOR
    • C0205 LEFT WHEEL SPEED SENSOR
    • C1249 STOP LIGHT SWITCH OPEN CIRCUIT
    I hope that was thorough enough. I hear and read a mixture of things, a 12v battery could be causing ALL of this. Some say odds of both front sensors going out is minimal, but, who knows. I will try cleaning them tomorrow and see if that helps. Battery replacement time? Thanks a bunch!

    12.4 isn't bad. is that a stone cold battery with everything off?

    Yes. But under load, we are going under 12v, hitting 11.8 at first, now, 11.5v

    isn't that natural for a battery under load? depends on the load i suppose. how old is it?

    I replaced the 12v with a Bosch AGM battery from Pep Boys $150. Not bad for AGM. No lights since.

    Good! I think you are saying no warning lights.
    If the warning lights come back, Fotomoto at Post#3 re: brake actuator is a possible explanation.
