These instructions apply to the Nissan Navara (D23/NP300) 2014-Present.
For other models, please choose your vehicle here.
The Nissan Navara D23, sold as the NP300 and built from 2014 onward, comes with a standard 16-pin OBD-II diagnostic socket like every modern vehicle. It accepts any generic code reader, Bluetooth adapter or professional scan tool, so you do not need Nissan-specific equipment for basic diagnostics. On this pickup the connector lives under the driver’s side of the dashboard and can be reached without taking off any trim, though it sits high enough that a torch and a bit of a stretch help.
OBD-II Port Location
On the D23 Navara the diagnostic socket is beneath the dashboard on the driver’s side, tucked up under the steering column. It is not out in plain sight in the middle of the footwell; instead the lower dash trim comes down fairly low, and the connector is up behind that edge, roughly to the left of or below the steering column depending on how you are looking. Reach up into the space under the wheel and feel along the underside of the dash and you will find the black 16-pin socket. There is no screwed-on cover to remove, so once your hand is in the right spot the plug goes straight in.
Before You Plug In
- Park on level ground, set the handbrake and turn the ignition off before you start feeling around under the dash.
- Keep a torch handy, because the socket sits up behind the lower dash lip where daylight does not reach.
- Slide the driver’s seat back to give yourself room to lean in and reach up under the steering column.
- Confirm your scan tool uses the standard 16-pin OBD-II plug, which is what this generation is fitted with.
How to Access the Connector
- Open the driver’s door and get low, either kneeling outside or sitting sideways in the seat.
- Look up under the steering column toward the underside of the lower dash trim.
- Shine the torch or run your fingers along that upper edge until you locate the black 16-pin socket set back behind the trim.
- Align your tool’s plug with the socket and push it in squarely until it seats firmly.
Tips for Safe Use
- Guide the plug in straight and gently; the socket is awkward to see, so take care not to bend a pin by forcing it at an angle.
- Only turn the ignition to “on” once the tool prompts you, and keep the engine off unless a live-data test needs it running.
- Remove any dongle when you finish, as one left plugged in draws current and can drain the battery if the truck stands for a while.
- Stick to a recognised scan-tool brand to avoid unreliable adapters that can confuse the CAN network.
Frequently Asked Questions
Where is the OBD-II port on a 2014-present Nissan Navara D23?
It is under the dashboard on the driver’s side, up behind the lower trim near the steering column. Reach up into the space under the wheel and feel along the underside of the dash to find the black 16-pin socket.
Why can’t I see the OBD-II socket on my NP300 Navara?
Because the lower dash trim hangs down low and the connector sits up behind it rather than facing the footwell. Get down low, shine a torch upward under the column, or simply feel along the top edge of the trim and you will find it.
Does the D23 Navara need any panel removed to reach the port?
No. There is no cover to unscrew. The socket is set back under the dash, so it just takes a bit of a reach rather than any dismantling.
Will a generic OBD-II reader work on my Navara?
Yes. The D23 uses the standard 16-pin OBD-II connector with CAN, so any generic reader, phone dongle or professional scan tool built for OBD-II will connect and communicate.
