Your Nissan may have an OBD-style port, but it might use the Nissan Consult protocol instead of the standard OBD2. This can make connecting a typical OBD2 reader difficult. If your Bluetooth OBDII reader isn’t connecting, you likely need a Nissan Consult To Obd2 Adapter. This article explores options for connecting to your Nissan’s ECU.
Understanding the Nissan Consult Protocol
Nissan Consult is a proprietary diagnostic protocol used in many Nissan vehicles. While some Nissans have a standard OBD2 port and protocol, others, particularly older models or those with specific engines, might use a Consult port that looks like an OBD2 port but functions differently. This incompatibility is why a standard OBD2 scanner might not work.
Nissan Consult to OBD2 Adapter Options
One common solution is using a Nissan Consult to OBD2 adapter. This adapter allows you to connect a standard OBD2 scanner or diagnostic tool to your Nissan’s Consult port. There are several types of adapters available:
-
USB Consult Cables: These cables connect your Nissan’s Consult port to a computer via USB. You then use diagnostic software on your computer to communicate with the vehicle’s ECU. ECUTalk is one example of this type of interface, but it can be expensive. It’s important to note that some USB cables are only compatible with specific Nissan models and engines. For instance, ECUTalk specifically mentions compatibility with Patrol/Navara/Terrano with TB45E or non-CRD ZD30 engines and R50 Pathfinder with VG33E. They explicitly state it won’t work with true OBDII vehicles.
-
Bluetooth Consult Adapters: Similar to USB cables, these adapters utilize Bluetooth to establish a wireless connection between your Nissan and a smartphone or tablet. They often work with various diagnostic apps available on app stores.
-
Consult to OBD2 Converter Cables: These adapters physically convert the Consult port pinout to match the OBD2 standard. This allows you to use a standard OBD2 scanner with your Nissan. However, confirming compatibility with your specific Nissan model and year is crucial as pinouts can vary. Compatibility also depends on the scanner’s ability to interpret the Consult protocol even after the physical pin conversion.
Choosing the Right Adapter
Selecting the right adapter depends on your needs and budget.
-
Cost: Generic Consult to OBD2 adapters are generally more affordable than specialized options like ECUTalk.
-
Functionality: Consider what you need the adapter for. If you only require basic fault code reading and clearing, a cheaper adapter might suffice. However, for advanced functions like relearning procedures and live data monitoring, a more sophisticated adapter or software might be necessary.
-
Compatibility: Ensure the adapter is compatible with your specific Nissan model and year. Research online forums and consult product descriptions for compatibility information.
Using the Adapter
Once you have the appropriate adapter, connect it to your Nissan’s Consult port and your diagnostic tool. Then, use your chosen software or app to communicate with the vehicle’s ECU. You can then perform functions like scanning for fault codes, deleting codes, running relearning procedures, and monitoring live data. Remember, using the correct software is crucial for accessing all the features and data available through the Consult protocol.
Conclusion
Connecting to a Nissan with a Consult port can be challenging, but a Nissan Consult to OBD2 adapter offers a solution. By understanding the different types of adapters and choosing the right one for your needs, you can effectively diagnose and troubleshoot your Nissan. Always verify compatibility with your specific vehicle before purchasing any adapter.
