    CAUTION:

    Always turn the ignition off when installing or removing the ECM connectors in order to prevent damage to the components.

    CAUTION:
    • Turn the ignition OFF when installing or removing the control module connectors and disconnecting or reconnecting the power to the control module in order to prevent internal control module damage.
    • Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle battery.
