Connect the Hi-Scan Pro to the vehicle data link connector located underneath the dash panel.

Turn the ignition key to "ON" position and turn on the Hi-Scan Pro .

Check for diagnostic trouble codes.

If a fault code is found, then replace the appropriate component. Never attempt to repair the component.

If the Hi-Scan Pro finds that a component of the system is faulty, there is a possibility that the fault is not in the components but in the SRS wiringor connector.
