Mitchell manual says bleeding is done with the brake pedal, nothing else.
However (and I take zero responsibility if you fry your entire ABS system).....

RELAYS

Pump Motor Relay

1) With ECU connector still unplugged, turn ignition switch to the "ON" position. Jumper ECU terminal No. 28 to ground.


NOTE: Relay should not remain grounded for more than 2 seconds or damage to relay may occur.

2) Hydraulic Modulator should operate while jumper is installed.
