The first-generation Nissan Note (E11 chassis, 2006-2013) comes with the standard 16-pin OBD-II diagnostic connector fitted to every car of this period. It is the socket you plug a code reader or diagnostic app into to read fault codes, view live engine data and clear a warning light after a repair. On this Note the port sits under the dashboard within easy reach, so no trim needs to come off to get to it.
OBD-II Port Location
On the Nissan Note E11 the OBD-II socket is under the dashboard on the driver’s side, close to the steering column and near the interior fuse box that sits at the lower end of the dash. On this model the fuse panel has a small removable cover, and the diagnostic connector is positioned right by it, low under the dash and facing down toward the footwell. If you pop off the fuse-box cover you will usually see the 16-pin socket alongside the fuses; if it stays clipped to the underside of the dash, feel along from the steering column toward the door to find it. Nothing beyond that fuse cover needs disturbing to reach it.
Before You Plug In
- Park on level ground, apply the handbrake and turn the ignition off before reaching under the dash.
- Keep a torch or phone light ready, as the footwell and fuse-box area are shaded.
- If the connector sits behind the fuse-box cover, ease that small panel off gently with your fingers first.
- Confirm the connector shape: a trapezoidal 16-pin socket, wider along one edge, so the plug fits only one way.
How to Access the Connector
- Open the driver’s door and, if needed, slide the seat back to give yourself room to lean into the footwell.
- Look under the lower dash near the steering column and locate the interior fuse-box cover; unclip it if the socket is behind it.
- Find the downward-facing 16-pin connector, line the plug up the right way round and push it in until it seats firmly.
- Turn the ignition to “on” (or start the engine if your tool requires it) so the port is powered and the reader wakes up.
Tips for Safe Use
- Connect and disconnect the tool with the ignition off to avoid a stray reading or a momentary glitch.
- Refit the fuse-box cover afterwards so it clips back cleanly and nothing rattles under the dash.
- Pull the plug straight out rather than at an angle so the pins stay true over time.
- If a reader won’t connect, confirm the ignition is on and check the cabin fuse feeding the socket before suspecting a fault.
Frequently Asked Questions
Where is the OBD-II port on a 2006-2013 Nissan Note?
It is under the dashboard on the driver’s side, close to the steering column and right by the interior fuse box, facing down into the footwell. On this model the socket often sits behind the small fuse-box cover.
Do I need to remove anything to reach it?
At most you unclip the small fuse-box cover by hand. No screws or larger trim panels need removing to reach the connector on the Note E11.
Will any OBD-II reader work on the first-generation Note?
Yes. Every Note from the 2006-2013 E11 range is OBD-II/EOBD compliant, so any standard 16-pin reader or app-based Bluetooth dongle will connect and read engine and emissions data.
The port has no power – what should I check?
Pin 16 draws from the battery through an interior fuse. If the tool stays dark, turn the ignition on, then check the relevant cabin fuse for continuity before assuming the socket or its wiring is faulty.
Once the port lets you read the codes, the next step is understanding what they mean; if a particular fault code appears, look it up on autodtcs.com.
