Understanding OBD-II Scanners and DTC Codes
An OBD-II scanner accesses your car’s onboard computer through the OBD-II port, a standardized connector found in most vehicles manufactured since 1996. The scanner reads Diagnostic Trouble Codes (DTCs), which are error codes triggered when the car detects an issue.
DTCs consist of a five-character alphanumeric code. The first letter indicates the system affected (P for Powertrain, B for Body, C for Chassis, U for Network). The second character denotes whether the code is generic (0) or manufacturer-specific (1). The third character identifies the specific subsystem, and the final two characters pinpoint the exact fault.
Choosing the Right Bluetooth OBD2 Scanner
Consider these factors when selecting a Bluetooth OBD2 scanner:
- Compatibility: Ensure the scanner is compatible with your car’s make and model.
- Features: Determine the features you need, such as live data, smog check readiness, and specific diagnostic capabilities.

- Reviews and Ratings: Check customer reviews and ratings on Amazon to gauge the scanner’s performance and reliability.
- Price: Bluetooth OBD2 scanners range in price. Set a budget and find a scanner that offers the best value for your needs.
