ABS stays on and trac. lite. brakes are fine. dO i need a new ABS molecule

i dont think so. the ABS molecule?what is that.if the ABS computer was bad you would know,your brakes would react when you drive and brake on slippery surface.you have a ABS sensor on your trucks rear end check to see if there is not a brake in the wire or have the sensor check with an ohms metter .that sensor may be faulty........................mac33
