E50 14 Pin Consult Port
The earlier models of the Elgrand E50 ('97 - '00 pre facelift) are all equipped with the 14 Pin Nissan Consult 1 port. The port can be found to the left of the bonnet release catch under the dashboard and is grey in colour (pictured right). To be able to read error codes, clear stored error codes and perform data logging, you will need a Consult 1 cable (pictured right). The most common lead to get is the Consult to USB which will allow you to connect directly to a laptop, although you can get USB to Micro USB adapter to use with mobile phones and/or tablet's (not iPhone).
You will also need to get the necessary software to read the codes installed on your laptop. The most common software is ECU Talk, which is free and available from the | ECU Talk Website. You will also need to download and install the USB drivers so that your computer can connect to your Elgrand, you can download those from ftdichip.
Once you have located the software and drivers for your computer and operating system, install them, and then take your laptop to your Elgrand. Connect the cable to your laptop and then plug the Consult plug in. Open up ECU Talk, which will present you with a drop down box. You need to select com port 4 "COM4".
Once you have done that, turn the ignition on, but DO NOT start the engine. This will allow ECU talk to communicate with the ECU via the cable. Once communication has been successful, you can start the engine (not required unless data logging).
Once ECU Talk has communicated with your on board ECU, you will see a screen with a list of tabs along the top (pictured left). The first of which reads "Gauges". This tab will allow you to monitor a number of key sensors whilst the engine is running.
Select the sensors you wish to monitor and press the "Display Gauges" button at the bottom. This will resent you with a screen with a number of dials (pictured left) that you can use to measure sensor readings. Using the correct combination of sensors is a great way to find the root cause of a problem you may be having.
The next tab along the top is "Faults". Clicking this tab will give you a list of error codes. You should see a "Code 55" (pictured right) which is "No Errors". If you see any others, please check out the List of Consult Error Codes to see what the problem is.
