    Default Catalyst System Low Efficiency

    Have a vehicle with codes P0420 Catalyst System Low Efficiency bank 1, P0430 Catalyst System Low Efficiency bank 2, Can I set {C1701} Catalyst Diagnostic Test to "Disable" to stop these codes or do I need to change P0420,P0430 DTC Type to X:Not Reported and also maybe disable the DTC MIL for these to NO MIL?
    It's all good until it goes "Bang"

    Default

    You're in Australia, so set just the catalyst codes to X, and leave the MIL on.
