Problem-Engine Vision Display does not properly display data from the engine control
Observe the "EVIM Statistics" screen with the service tool status screens. Confirm that the PL1000T is receiving EVIM messages and that the PL1000T is transmitting EVIM messages. The number of messages for both transmit and receive should occasionally increment.
If the "Number of Engine Vision Display Messages Received" does not increment, and the "Number of Engine Vision Display Messages Transmitted" does increment, this indicates the "Engine Vision Display" is not attempting to communicate with the PL1000T.
The communication port configurations should be checked in order to confirm that the configurations are the same for the PL1000T and the "Engine Vision Display".
The harness between the "Engine Vision Display" and the PL1000T should be analyzed and repaired.
If the "Number of Engine Vision Display Messages Received" does increment, and the "Number of Engine Vision Display Messages Transmitted" does not increment, this indicates the PL1000T is not attempting to communicate with the "Engine Vision Display".
Confirm that the "EVIM Enable Status" is set to "Enabled".
The Cat Datalink harness should be analyzed and repaired.
