is there any way to run the abs self diagnosis without using a scanner? I just bought the truck and the brake pedal goes to the floor. the resivour is full and I don't see any leaks.

 

Hi, there is no way to get the code without a scanner. You might to deeply check your braking system. Make sure there is no air in the system, that the wheel cylinders are working properly, springs are good, slide pins are not seize or calipers.
