For Acura owners and car enthusiasts alike, understanding your vehicle’s performance and health is paramount. While your Acura’s dashboard provides essential information, there’s a wealth of data hidden beneath the surface, accessible through On-Board Diagnostics II (OBD2) and specifically, Parameter IDs (PIDs). This article delves into the world of Acura Obd2 Pids, explaining how you can unlock advanced monitoring capabilities beyond the standard displays.
Understanding OBD2 PIDs: Standard vs. Custom
OBD2 PIDs are codes used to request data from your vehicle’s computer. Standard PIDs are universal across most vehicles and provide basic information like engine coolant temperature, RPM, and vehicle speed. However, manufacturers like Acura utilize custom or manufacturer-specific PIDs to monitor a broader range of parameters unique to their vehicles. These custom PIDs are crucial for accessing detailed data not available through standard OBD2 readings.
Acura leverages these custom Mode 22 PIDs extensively to monitor sensors, counters, and data points far beyond the standard set. This opens up exciting possibilities for owners who want to keep a closer eye on systems like transmission temperature, individual cylinder activity, and tire pressure monitoring system (TPMS) details.
Why Use Custom Acura OBD2 PIDs?
Accessing Acura’s custom OBD2 PIDs provides several key advantages:
- Enhanced Monitoring: Track critical parameters not displayed on your dashboard, such as transmission fluid temperature, which is vital for maintaining your Acura’s longevity, especially for models with advanced transmissions like the 9-speed automatic.
- Proactive Maintenance: By monitoring parameters like ATF temperature, you can identify potential issues early on, preventing costly repairs down the line. For example, consistently high transmission temperatures might indicate a need for fluid change or further inspection.
- Performance Insights: For enthusiasts, PIDs like input and output shaft speeds can offer valuable insights into transmission performance under various driving conditions.
- Customizable Dashboards: Using OBD2 apps and adapters, you can create personalized dashboards displaying the exact data points you are most interested in monitoring.
Tools for Accessing Acura OBD2 PIDs
To tap into Acura’s custom PIDs, you’ll need a few key tools:
- OBD2 Scanner/Adapter: An ELM327-compatible adapter (Bluetooth or WiFi) is essential. These adapters plug into your Acura’s OBD2 port, typically located under the dashboard.
- OBD2 Software/App: Software like CarScanner (iOS) and Torque (Android) are popular choices. These apps allow you to input custom PIDs and formulas to interpret the data received from your Acura. CarScanner, for example, offers user-friendly features for adding custom sensors and automatically converting units. Torque provides a flexible equation-based system for data interpretation.
Example Acura OBD2 Custom PIDs
Here are some examples of custom OBD2 PIDs for Acura vehicles, particularly the 2G Ridgeline, which can be adapted for other Acura models. Note that PID compatibility may vary depending on the specific Acura model and year.
| Item | PID | Formula | Units | Custom Header | Applicable To |
|---|---|---|---|---|---|
| ATF Temperature | 222201 | C: AA F: AA*9/5-40 | °C/°F (offset from -40) | 6AT (2017-2019) | 6-Speed Automatic |
| ATF Temperature | 223083 | C: O-40 F: 9/5*O-40 | °C/°F (offset from -40) | 9AT (2020+) | 9-Speed Automatic |
| Current Gear | 222201 | AC | Range: 0-15 | 6AT (2017-2019) | 6-Speed Automatic |
| Current Gear | 223086 | U | Range: 0-15 | 9AT (2020+) | 9-Speed Automatic |
| AT Input Shaft Speed | 222201 | H*256+I | rpm (0-8000) | 6AT (2017-2019) | 6-Speed Automatic |
| AT Output Shaft Speed | 222201 | J*256+K | rpm (0-8000) | 6AT (2017-2019) | 6-Speed Automatic |
| Outside Air Temperature | 227028 | CarScanner: ShortSigned(Q,R) | °F/°C (display setting) | 18DA60F1 | All? |
| Cylinders Active (VCM) | 222615 | AY | # of cylinders (3 or 6) | All? | All? |
| TPMS Pressures | 226001 | FL: K*256+L … RR: M*256+N | kPa | 18DA26F1 | All? |
| TPMS Temperatures | 226001 | FL: Z … RR: AA | °C | 18DA26F1 | All? |
Note: ‘All?’ indicates potential applicability to various Acura models, but verification for your specific model is recommended. The “Custom Header” 18DAEFF1 is often a default for ELM327 dongles, but headers like 18DA60F1 and 18DA26F1 may also be necessary for specific PIDs.
