    Hi

    Changed my 12 volt today with a yellow top. After starting car found brake warning light on, is the something that will reset when driving?

    Thanks

    I assume you are referring to the 'black box', next to the battery. That is actually an emergency power source for the braking system.

    Sometimes a quick, short, tiny thread can solve a head scratching problem quicker than a lengthy thread with lots of well versed Prii enthusiasts. OP, I want to thank you for a concise solution. I too had this problem and went out to the battery and found that I had failed reattach the wire going into the brake assist box next to the battery.

    I shake my head and kick my toe into the ground wondering why.
