    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.
    • In order to prevent any possible electrostatic discharge damage to the control module, do no touch the connector pins or the soldered components on the circuit board.
    • Remove any debris from around the control module connector surfaces before servicing the control module. Inspect the control module connector gaskets, and ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the control module.
