the brake light on my dash on my dash is blinking. it lights up for a second, then blinks 5 times, steady for a second, then blinks 5 more times, and it does this the whole time the truck is running. what would cause this?

 

I know that when the light blinks on a honda it is an ecu code. you might want to check with your mechanic

 

I agree.
And check your brake fluid. I had a 92 corsica. The brake light was on for almost a year, all it needed was brake fluid.
