I haven't bled the brakes lately, but I can give that a try.

DTC 11: ABS Solenoid Relay Circuit: This relay gives power to each ABS Solenoid. After the ignition switch is turned on, if the initial check is ok, the relay goes on.

DTC 13: ABS Motor Relay Circuit: The ABS motor relay supplies power to the ABS pump motor. While the ABS is activated, the ECU switches the motor relay on and operates the ABS pump motor.

I can clear each of these codes with the ignition swich on, the diagnostics jumper in place and pumping the brakes. However, as soon as I turn on the car move a few feet and apply the brakes (without activating the ABS) one of the codes reappear.
