What is included in the diagnostic and repair information section?

The diagnostic and repair information section typically includes diagnostic charts, part specifications, emission control diagrams, and other essential resources that help an emissions inspector understand vehicle systems and how to address issues effectively. The function of this section is crucial as it provides the necessary tools to identify problems related to emissions and perform the appropriate repairs to ensure compliance with environmental regulations.

In this context, the four gas analysis and OBDII practice test could potentially assist in understanding emissions performance and onboard diagnostics, but it does not form part of the diagnostic and repair information section itself. Therefore, it doesn't include the comprehensive details and charts that are integral for troubleshooting and repairs. Instead, it focuses more on testing knowledge rather than providing repair guidance, making it an inappropriate choice for what is specifically included in the diagnostic and repair information section.
