11.3.2.1 Communication Failures Definition
Two types of communication failures are diagnosed. The communication failures are
checked separately for each IDU channel.
11.3.2.2 ‘Bad Communication’ fault
The system keeps a balance of a good/bad communication packet ratio for each active
communication channel. When the ratio getting high , system enters ‘Bad Communication’
fault.
11.3.2.3 ‘No Communication’ fault
If no legal transmission or no message received for 30 seconds, system enters ‘No
Communication’ fault.
When in ‘No Communication’ fault, the system will act as following:
•
If there is no communication in all channels, the following will be performed:
1. The unit changes to SB.
2. The system will scan all the communication.
