This document provides information on using OBD2 Bluetooth scanners with Toyota Prado vehicles, particularly those with M-OBD systems. It addresses compatibility issues, scanner selection, and troubleshooting common problems.
Problem: Selecting a Compatible OBD2 Scanner
Owners of Prado vehicles, especially those with M-OBD systems, have reported varying degrees of success when using OBD2 Bluetooth scanners. Key concerns include:
- Scanner compatibility with specific Prado models (e.g., Japanese market TX models).
- Reliability of fuel economy readings.
- Ensuring the purchased scanner is a genuine unit, not a counterfeit.
- Auto power down of the OBD2 unit after the car ECU shuts down.
Solution: Recommended OBD2 Scanner and Purchasing Advice
- OBDLink LX is recommended as a reliable option.
- Purchase from reputable sources like Scantool.net to avoid counterfeit products.
Additional Notes
- Some eBay-sourced OBD2 units have been reported to function correctly. If encountering issues, verify the unit’s MAC address.
- For 90 series Prados with the 5VZFE 3.4 petrol engine (and a rectangular OBD connector), an adapter can be purchased from the same supplier as the OBD2 scanner.
- Compatibility issues may arise when reading transmission temperature on certain Prado models.
