Identifying Your Acura’s OBD System

Pinpointing the exact year your Acura transitioned to OBD2 can sometimes be tricky. While the general rule is that 1996 and later models are OBD2 compliant, some 1995 models also adopted the system. The best way to confirm your car’s system is to check the Vehicle Emission Control Information (VECI) label usually located under the hood or on the driver’s side doorjamb. This label will clearly indicate the OBD system.

Another reliable method is to physically inspect the diagnostic connector. OBD1 connectors vary in appearance and location, whereas OBD2 connectors are standardized 16-pin trapezoidal ports usually situated under the dashboard on the driver’s side.

Why the Switch to OBD2?

The Environmental Protection Agency (EPA) mandated OBD2 in 1996 to standardize emissions regulations and improve diagnostic capabilities. OBD2 offers more comprehensive diagnostics, allowing scanners to access more data from the car’s computer, including real-time sensor readings and diagnostic trouble codes (DTCs). This standardization also makes it easier for mechanics to diagnose and repair emission-related issues. OBD2 is a significant advancement over OBD1. Need to read your transmission codes?
