My 2005 prius with 166500 miles has these lights on dash, (!) BRAKE and ABS, and there is a high pitch alarm, also brake pedal is hard and brakes don't work as well as they did just before warnings came on. Toyota dealer says the abs main fuse is blown. $300+ to replace main fuse. Service rep says he cant be sure the new fuse wont blow. He says complete abs system diagnosis could cost as much as $700. Anyone heard of this problem and have any advice? Thanks.
