• C Codes (Chassis): These codes involve the braking system, suspension, and steering.
• U Codes (Network): These codes indicate communication issues between the vehicle’s computer systems.

2.1.2 Interpreting DTCs

How can you interpret DTCs to understand your vehicle’s problems?

Interpreting DTCs involves using a scan tool to retrieve the codes and then researching their meaning. Many scan tools provide a brief description of the code, but more detailed information can be found in repair manuals or online databases. It’s important to note that a DTC only points to a potential issue, and further diagnosis is often needed to pinpoint the exact cause.

2.2 Conducting a Preliminary Inspection

What steps can you take to conduct a preliminary inspection of your vehicle before visiting a diagnostic shop?

Before taking your car to a diagnostic shop, you can perform a basic inspection to gather information:
