1. What Does “Scan and Solve” Mean in Auto Repair?

“Scan and solve” refers to the method of using electronic diagnostic tools to identify problems within a vehicle’s systems and then implementing the necessary repairs to resolve those issues. This process begins with scanning the vehicle’s onboard computer for diagnostic trouble codes (DTCs), which provide clues about potential malfunctions. Once the codes are retrieved, technicians use this information to diagnose the root cause of the problem and perform the appropriate repairs.

• Diagnostic Tools: These include scan tools, multimeters, and other devices used to assess vehicle systems.
• Diagnostic Trouble Codes (DTCs): Codes generated by the vehicle’s computer to indicate a problem.
• Repair Procedures: The steps taken to fix the identified problem, which may include replacing parts or making adjustments.

1.1 How Scan and Solve Works

The scan and solve process typically involves these steps:

1. Scanning: Connecting a scan tool to the vehicle’s diagnostic port to read DTCs.
2. Diagnosis: Interpreting the DTCs and using other diagnostic methods to pinpoint the issue.
3. Repair: Performing the necessary repairs, which may include replacing faulty parts, repairing wiring, or reprogramming the vehicle’s computer.
