It verifies that the data selector can be set and cleared at each isolated node and that all interframe buffers within the isolated segment are sized to agree with the ECD.
  • Page 329 TABLE A (Contd) SSI ULN DIAGNOSTIC PHASES FAILING DESCRIPTION OF CIRCUITRY TESTED PHASE Requests the relay module to write a message with bad parity from a BISO node into the isolated segment. The write is expected to block when the RAC at the node being diagnosed detects bad parity.
