    Default Ecu Connections

    just a quick one guys

    on my 2.8 signum

    is it possible to unplug my 2 ECU connections in the engine compartment at the back of the engine
    to get to a pipe underneath ?

    or will the ECU reset ?

    tech 2 is the only way to reset ecu. or op-com etc etc. The only thing happen when you disconnect battery is it resets any fault codes stored. if it a facelift you will not have to put code in for radio, if it pre facelift you will. everything else will be fine.
