    CEM is the head-computer from the car.
    The modules, or nodes, are micro computers that are controlled by the
    CEM (central electronic module)
    There are about 15 operative modules in a S80 and they control almost
    all of the electrical functions in the car e.g. climate control, ABS breaks
    and the electrical controls in the driver door.

    You probably mean ECM-260A and ECM-270A
    Only the dealership VIDA can read CEM codes.
    There are not any CEM codes 260A or 270A
    that I could locate.
    Generic code readers can read the ECM computer.

    ECM-260A Long term fuel trim Lower or upper limit
    Lower limit could be intake vacuum leakage, high fuel pressure,
    leaking fuel injector(s), Defective AMM, engine oil lever too high,
    to defective 02 sensor(s).
    Upper limit could be intake air leak, low fuel pressure to
    defective 02 sensor.

    ECM-270A Adaptive Lombda control Bank 2
    Defective 02 sensor to possibly a fault of the 260A codes
    listed above.
