Essential Features of a Car Diagnostic Scanner
Types of Car Diagnostic Code Scanners
- Code Readers: Entry-level devices designed to read and clear basic diagnostic trouble codes (DTCs).
- OBD-II Scanners: Offer more advanced features like live data streaming, freeze frame data, and emissions readiness checks.
- Professional Scanners: Comprehensive tools used by mechanics and technicians, offering extensive diagnostic capabilities, including bi-directional control, module coding, and advanced programming functions.
Understanding Diagnostic Trouble Codes (DTCs)
Diagnostic trouble codes are standardized codes that indicate a specific malfunction within your vehicle’s systems. When your car’s onboard computer detects a problem, it generates a DTC, storing it in its memory.
DTC Structure:
- The first character indicates the system the code relates to (e.g., “P” for Powertrain).
- The second character refers to a specific subsystem (e.g., “0” for Fuel and Air Metering).
- The last two digits specify the actual fault within that subsystem.
