    ACT fault codes

    got these codes, can anyone advise why
    u2100 - 4 - can-bus malfunction - present
    u2108 - 4 - can-bus no communication with abs/tc - present
    p0530 - 1 - a/c refrigerant pressure sensor circuit high input - present
    p1490 - 2 - auxiliary cooling pump relay short to ground - present

    i know the air con has no gas, i dont have a TC button and the TC & abs lights are on the dash, speedo etc still working so dont think its the hub.

    1 thing i should mention is ive just changed the dash harness as i fitted climate control but everything plugged right up.
    car drives fine (over revs when changing gear though??)

    cheers guys
