Return Values

  • -1: There was no request yet or no error occurred.
  • 0: The response wasn’t received in expected time.
  • 1: Time for transmission of the CAN frame on the receiver side expired.
  • 2: Time for transmission of the CAN frame on the sender side expired.
  • 3: Time until reception of the next Flow Control expired.
  • 4: Time until reception of the next Consecutive Frame expired.
  • 5: Not specified communication error.
  • 6: The response wasn’t received in the expected extended time.
  • 7: A previously queued request was canceled.
  • 8: Not possible to forward the message to the Bus System Proxy (not defined/open or driver error).
  • 9: The response wasn’t received in the expected RC21 completion time.

​
FlexRay Specific ComErrors

  • 100: The request to send some data was rejected since another transmission is in progress.
  • 101: A reception was active when FF or SF was received.
  • 102: A negative ACK was received for acknowledged connections.
  • 103: The bus did not confirm transmission of a frame in time.
  • 104: The transmitter did not receive a FC (or AF) in time.
  • 105: The receiver did not receive the next CF in time.
  • 106: The peer rejected the data since it is too long.
  • 107: Peer sent an undefined ACK.
  • 108: A message received is not fit for processing, e.g. a First Frame where a Single Frame would have sufficed.
  • 109: Receiver has sent too many wait frames and must therefore abort the transfer!
  • 110: Receiver has requested the resending of an illegal frame, e.g. the First Frame.
  • 111: ISO: Receiver requested the transfer to be aborted.

​
K-Line Specific ComErrors

  • 200: StartCommunication request wasn’t answered by the ECU.

​
General Error Codes

  • 600: The requested function isn’t supported.

Example

testcase TC()
{
  DiagRequest XY_Read req;
  int err;

  TestStep("Test", "Step");
  DiagSetTarget("ECU");
  DiagSendRequest(req);
  if (0 == TestWaitForDiagResponse(req, 2000))
  {
    err = DiagGetLastCommunicationError();
    write("LastCommunicationError=%d", err);
  }
}
