Once the scanner is connected, you can start reading and interpreting the OBD2 codes. These codes provide valuable information about your vehicle’s health and can help you diagnose and fix problems.

4.1 Understanding Diagnostic Trouble Codes (DTCs)

Diagnostic Trouble Codes (DTCs) are codes stored in the vehicle’s computer when a problem is detected. According to the National Institute for Automotive Service Excellence (ASE), DTCs are standardized across all OBD2-compliant vehicles, making it easier to diagnose issues regardless of the car’s make and model. These codes are essential for pinpointing the source of the problem and guiding the repair process.

4.2 Common OBD2 Codes for FR-S Vehicles

Here are some common OBD2 codes that FR-S owners might encounter:

Code	Description	Possible Causes
P0171	System Too Lean (Bank 1)	Vacuum leak, faulty MAF sensor, fuel pump issue
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, ignition coils, fuel injectors
P0420	Catalyst System Efficiency Below Threshold (Bank 1)	Faulty catalytic converter, exhaust leak, O2 sensor issue
P0442	Evaporative Emission Control System Leak Detected (Small Leak)	Loose gas cap, damaged EVAP hose, faulty purge valve
P0012	“A” Camshaft Position – Timing Over-Retarded (Bank 1)	Low oil level, faulty oil control valve (OCV), or mechanical timing issue

4.3 Step-by-Step Guide to Reading Codes

Follow these steps to read the OBD2 codes using your scanner:

1. Connect the Scanner: Plug the OBD2 scanner into the port and turn on the ignition.
2. Select “Read Codes”: Navigate to the “Read Codes” or “Diagnostic Codes” option on the scanner’s menu.
