For Honda vehicle owners seeking in-depth diagnostics and monitoring beyond standard displays, the world of custom OBD-II Parameter IDs (PIDs) offers a powerful solution. Utilizing an OBDII scanner with custom PID capabilities opens up access to a wealth of sensor data not natively shown on your dashboard. This guide serves as a starting point, much like a “Best Obdii Scanner Review Wiki” would, to explore the potential of custom PIDs for Honda vehicles, focusing on practical examples and tools.
Understanding OBD-II PIDs is crucial. OBD-II (On-Board Diagnostics II) is a standardized system in modern vehicles that allows diagnostic tools to communicate with the car’s computer. While standard PIDs provide common data points across manufacturers, carmakers like Honda also employ custom, manufacturer-specific PIDs. These custom PIDs unlock access to a wider array of information, from transmission temperatures to individual sensor readings, enhancing your diagnostic abilities.
To tap into these custom Honda PIDs, you’ll need the right tools. OBD-II scanners compatible with ELM327 adapters are popular and versatile. These scanners, often used with smartphone apps like CarScanner or Torque Pro, bridge the gap between your vehicle’s OBD-II port and your device. These apps allow you to input custom PIDs and formulas, effectively creating a custom dashboard tailored to your monitoring needs. CarScanner, for example, simplifies unit conversion, while Torque provides flexible formula inputs, as detailed in their respective documentation.
While some scan tools, like ScanGauge, offer custom PID functionality, they may employ proprietary formats that are less easily transferable. The focus here is on open and accessible methods using ELM327-compatible scanners and widely used apps. This approach aligns with the collaborative spirit of a “best obdii scanner review wiki,” encouraging shared knowledge and ease of use across different tools.
For Honda 2G Ridgeline and potentially some later 1G models (2009+ using CAN 29-bit protocol ISO 15765-4), the following custom PIDs have been identified. Note that transmission PIDs will differ significantly between 6-speed (6AT) and 9-speed (ZF-9/9AT) automatic transmissions due to the separate Transmission Control Module (TCM) in the ZF-9. Default headers for ELM-327 dongles are often 18DAEFF1.
| Item | PID | Formula | Units | Custom Header | Applicable to |
|---|---|---|---|---|---|
| ATF Temp | 222201 | C: AA F: AA*9/5-40 | °C/°F (offset from -40) | 6AT | 2017-2019 |
| ATF Temp | 223083 | C: O-40 F: 9/5*O-40 | °C/°F (offset from -40) | 9AT | 2020+ |
| Current Gear | 222201 | AC | None, range: 0-15 | 6AT | 2017-2019 |
| Current Gear | 223086 | U | None, range: 0-15 | 9AT | 2020+ |
| AT Input Shaft Speed | 222201 | H*256+I | rpm (0-8000) | 6AT | 2017-2019 |
| AT Output Shaft Speed | 222201 | J*256+K | rpm (0-8000) | 6AT | 2017-2019 |
| Outside Air Temp | 227028 | CarScanner: ShortSigned(Q,R) | °F/°C (display setting) | 18DA60F1 | All ? |
| Cylinders Active (VCM) | 222615 | AY | # cylinders (3 or 6) | N/A | All ? |
This table provides a starting point for customizing your OBD-II scanner for Honda vehicles. For example, monitoring ATF temperature, especially in demanding conditions, can provide valuable insights into transmission health. Similarly, observing cylinder activation (VCM) can be informative for engine performance analysis.
Further expanding this “best obdii scanner review wiki” for Honda custom PIDs relies on community contribution. Sharing your discoveries and experiences with different Honda models and PIDs will enrich this resource, making it even more valuable for enthusiasts and DIY mechanics. As the data expands, this guide can evolve into a more comprehensive resource, much like a detailed wiki, for Honda OBD-II custom PIDs.
