I would check the connectors for the sensors especially the front. There is a bulletin for bad connections causing a false abs conditions. You might try to disconnect them one by one and pinch the pins(to make them fit tight) and add dielectric grease)
Since you do not have a scanner to watch the wheel signals from the sensors this might be the best try. You could even ohm the connectors, back probe them and see if there is high resistance(you will need to disconnect the ebcm to isloate the circuit)
let me know what you find
Anti-Lock Brake Module is located at the LH front of the vehicle, on front of the upper radiator support.
