Navigating the world of car diagnostics can be tricky, especially when it comes to understanding OBD (On-Board Diagnostics) standards. For owners of the Ford AU Falcon, a common question arises: does my vehicle fully comply with OBD2, and what’s the best scan tool to use? While the AU Falcon, particularly models around the year 2000, is equipped with what appears to be an OBD2 connector, the reality of its diagnostic protocol compatibility can be more complex.
The discussion in online forums highlights this very confusion. Owners have reported that standard OBD2 scanners often fail to communicate effectively with their AU Falcons. This leads to the suspicion that despite having the physical OBD2 port, the vehicle might not adhere to the standard OBD2 protocols fully, or perhaps utilizes an earlier OBD standard like OBD1 in conjunction with the OBD2 connector.

Some theories suggest that Ford might have implemented an EEC-V system in the AU Falcon, possibly utilizing a Siemens K-Line protocol. This protocol, while using the OBD2 connector, may not be fully compatible with generic OBD2 scan tools designed for broader vehicle coverage. It’s mentioned that the Ford NGS (New Generation Star) tester, a tool specifically designed for Ford vehicles and dealerships, is known to work with the AU Falcon. This suggests that a Ford-specific or at least protocol-aware scan tool might be necessary.
Experiences shared by AU Falcon owners indicate that generic ELM327-based scanners, while connecting to the port, often fail to retrieve comprehensive data or fault codes. This reinforces the idea that the AU Falcon’s diagnostic system might operate outside the typical OBD2 parameters that these generic scanners are built to interpret.

So, what does this mean for the Ford AU Falcon owner looking to diagnose issues? It points towards the need for a more specialized approach to scanning. While your AU Falcon has an OBD2 port, for reliable diagnostics, you may need to consider scan tools that are:
- Ford Specific: Tools like the NGS tester or those designed to communicate with Ford’s EEC-V systems are more likely to be successful.
- Protocol Aware: Scanners that support a wider range of protocols beyond standard OBD2, potentially including Siemens K-Line or similar, might be required.
In conclusion, while the Ford AU Falcon presents itself with an OBD2 connector, don’t assume that any standard OBD2 scanner will fully unlock its diagnostic capabilities. Researching and choosing a scan tool that is known to be compatible with Ford vehicles of this era, or specifically supports the protocols potentially used by the AU Falcon, is crucial for effective car diagnostics at home.
