Purpose

Executes the ReadECUIdentification service. Returns ECU identification data.

Format 

        long ndReadECUIdentification(
       TD1 *diagRef,
       unsigned char mode,
       unsigned char dataOut[],
       long *len,
       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.

mode

Indicates the type of identification information to be returned. The values are application specific. Output

dataOut

Returns the ECU identification data.

len

On input, len must contain the dataOut array length. On return, it contains the number of valid data bytes in the dataOut array.

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.

Description

This function requests identification data from the ECU. mode identifies the type of identification data requested. The ECU returns identification data that dataOut can access. The dataOut format and definition are vehicle manufacturer specific.
