Purpose

Executes the DisableNormalMessageTransmission service. The ECU no longer transmits its regular communication messages (usually CAN messages).

Format

        long ndDisableNormalMessageTransmission(
       TD1 *diagRef,
       LVBoolean *requireResponse,
       LVBoolean *success);
      

Input

diagRef

Specifies the diagnostic session handle, obtained from ndOpenDiagnosticOnCANFD or ndOpenDiagnosticOnIPStack and passed to subsequent diagnostic functions. Normally, it is not necessary to manually manipulate the elements of this struct.

requireResponse

Indicates whether a response to this service is required. If *requireResponse is FALSE, no response is evaluated, and success is always returned TRUE. This parameter is passed by reference. Output

success

Indicates successful receipt of a positive response message for this diagnostic service.

Return Value

The return value indicates the function call status as a signed 32-bit integer. Zero means the function executed successfully. A negative value specifies an error, which means the function did not perform the expected behavior. A positive value specifies a warning, which means the function performed as expected, but a condition arose that may require attention.

Use the ndStatusToString function to obtain a descriptive string for the return value.
