Communication Adapter and/or Cables
1. Make sure that the firmware and driver files are
the most current files that are available for the
type of commun
ication adapter that is being used.
If the firmware and driver files do not match, the
communication adapter will not communicate with
the electron
ic service tool.
2. Disconnect the communication adapter and the
cables from t
he service tool connector. Reconnect
the communication adapter to the service tool
connector.
3. Verify that the correct cable is being used between
the communication adapter and the service tool
connector. R
