Function Syntax

long KLine_SetInitType(long initType)

Description

Configures the used initialization pattern.

Parameters

• initType: Initialization pattern
  • 1 = 5 baud init
  • 2 = fast init
  • 3 = no init pattern

Return Values

On success 0, otherwise a value less than 0.

Example

Example shows a test case that makes sure that an ECU does not respond to a request after a S3 timeout.

DiagRequest TesterPresent req;
long timeout_ms;
int status;
DiagSetTarget("DUT");

// Connect Channel
DiagConnectChannel()
status = TestWaitForDiagChannelConnected(2000);
    if (1 == status)
    {
        TestStepPass("Connected to target ECU");
    }
    else
    {
        TestStepFail("Error connecting to target ECU.");
    }

req.SendRequest();
    if (1 != TestWaitForDiagRequestSent(req, 1000))
    {
        TestStepFail("Request was not sent.");
    }
    if (1 != TestWaitForDiagResponse(req, 1000))
    {
        TestStepFail("No response received.");
    }

// StopCommunication command shall NOT be send after closing the channel.
KLine_SuppressAutomaticStopCommunication(1);
DiagCloseChannel();
    if (1== TestWaitForDiagChannelClosed(1000))
    {
        TestStepPass("Channel closed successfully.");
    }
    else
    {
        TestStepFail("Channel could not be closed.");
    }
    KLine_SetInitType(3);   // No Init

// Wait for a S3 timeout
timeout_ms = 6000;
TestWaitForTimeout(timeout_ms);

// Send again a tester present request
req.SendRequest();
TestWaitForDiagRequestSent(req, 1000);
    if  (1 == TestWaitForDiagResponse(req, 1000))
    {
        TestStepFail("Request answered in spite of a S3 timeout ");
    }
    else
    {
        TestStepPass("Request not answered due to S3 timeout.");
    }

DiagCloseChannel();
    if (1== TestWaitForDiagChannelClosed(1000))
    {
        TestStepPass("Channel closed successfully.");
    }
    else
    {
        TestStepFail("Channel could not be closed.");
    }

// Reset Settings
KLine_SetInitType(2); // Fast Init
KLine_SuppressAutomaticStopCommunication(0);
