Ok, here is the description for DTC 1: ABS pump motor over-run
-Air mixed in with ABS fluid
-Pressure switch stuck off
-Open circuit between the pressure switch and ABS control unit.
-Open circuit between the P-SW circuit between the pressure switch and body ground, poor body ground.
-Drop in pump discharge volume.
-Leaking modulator unit outlet valve.
-Leaking relief valve.
-ABS brake fluid leakage.
-Faulty ABS control unit.
So, sounds like for the most part it could be an easy fix. The last couple of options are what I would be concerned about...
I'm going to try and get my scanner working and scan in the TS pages for ya.. Don't hold your breath though, this scanner is posessed.
