Cat ET is not required in order to read diagnostic codes or to clear diagnostic codes. Cat ET can provide more information about the equipment faster than other methods of reading the codes. Cat ET will display information on the history of a diagnostic code and the parameter status of diagnostic codes. These features allow Cat ET to be a useful tool for troubleshooting.
Cat ET is used to communicate to Electronic Control Modules (ECM) via the service port.
Note: The service port is located on the right side of the seat for the operator and to the rear of the fuse panel.
