The motor below the ABS valve body was running continously after a trip. the body and the motor were hot. Pulled the motor control relay and the other control relay in the box atop the valve body. No diagnostic LEDflahes in the ABS controller in the trunk, but ABS light in the dash i s on. Bad relay or worse? Please offer suggestions or problem history. I have the FSM, it's logic paths are incomprehensible...............Brakes operate normally; just no ABS. thx

Relay failure is common and most logical explaination

Thx - new relays form Sewell enroute. The motor relay had a sticking contact when tested on the bench.
