so the reader says its the brake switch. ive replaced it twice now and the code still comes up when i hit 75 mph. third brake light works though. maybe something to do with the 2 brake light bulbs? dunno. what an annoying pain.

 

and solved. psm and abs code popped up at 75 mph. disappeared when the engine was shut off and then restarted.
recalled in a moment of brilliance that only one brake tail light was burnt out, so i replaced both of them. then both didnt work. finally clicked when i realized that i replaced the brake pedal switch and the third light would come on and not the two main brake lights. wrong fkn bulbs! replaced the two bulbs and viola no psm abs codes.
weird that the reader said it was a brake pedal switch when it was the wrong light bulbs.
what a pain. almost had me to the point of thinking i had to replace the 4 wheel speed sensors.
