8. Perform Additional Tests: Use the scanner to monitor real-time data, perform actuator tests, and access advanced functions as needed.

Interpreting Diagnostic Trouble Codes (DTCs)

DTCs are standardized codes that provide information about specific issues detected by the vehicle’s onboard computer. Each code consists of five characters:

• First Character: Indicates the system (e.g., P for Powertrain, B for Body, C for Chassis, U for Network).
• Second Character: Specifies whether the code is generic (0) or manufacturer-specific (1).
• Third Character: Indicates the specific system or component (e.g., fuel system, ignition system, etc.).
• Fourth and Fifth Characters: Provide more detailed information about the fault.

For example, a code like P0300 indicates a random or multiple cylinder misfire in the powertrain system.

Common OBD2 Codes and Their Meanings

Code	Description	Possible Causes
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, ignition coils, fuel injectors, vacuum leaks, low compression
P0171	System Too Lean (Bank 1)	Vacuum leaks, faulty oxygen sensor, low fuel pressure, contaminated mass airflow (MAF) sensor
P0420	Catalyst System Efficiency Below Threshold (Bank 1)	Faulty catalytic converter, oxygen sensors, exhaust leaks, engine misfires
P0101	Mass Air Flow (MAF) Sensor Range/Performance Problem	Dirty or faulty MAF sensor, intake leaks, wiring issues
P0301	Cylinder 1 Misfire Detected	Faulty spark plug, ignition coil, fuel injector, low compression
P0401	Insufficient EGR Flow	Blocked or faulty EGR valve, EGR passages, vacuum lines, differential pressure sensor
P0442	Evaporative Emission Control System Leak Detected	Loose or faulty fuel cap, damaged EVAP hoses, purge valve, vent valve
P0011	A Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)	Incorrect engine oil, malfunctioning oil control valve (OCV), worn timing chain or belt, faulty camshaft phaser

Tips for Effective Diagnostics
