Using service request numbers

The service request numbers (SRN) identify the component that detected the error code and describe the error condition.

For use by service providers.

Diagnostic applications report problems by using service request numbers (SRNs). Use the SRN information to identify a list of possible failing items and to find information about any additional isolation procedures.

Service request number formats:

If your code is in the following formats (xxxxx, xxx-xxx, xxx-xxxx, xxxx-xxx, xxxx-xxxx), it is an SRN.
