These instructions apply to the Nissan Micra Mk4 (K13) 2010-2017.

The fourth-generation Nissan Micra (K13, sold from 2010 to 2017) is fitted with the standard 16-pin OBD-II diagnostic connector, so a generic code reader, Bluetooth adapter or workshop scan tool will plug straight in. The port lets you read and clear fault codes, watch live engine data and check emissions readiness on this supermini. It sits within comfortable reach beneath the dashboard, so you can find it and use it without removing any panels or trim.
OBD-II Port Location
On the K13 Micra the diagnostic socket is on the driver’s side, up under the dashboard close to the fuse box and roughly beneath the steering column. It sits behind the small plastic cover that also gives access to the fuses on the lower dash, so it faces down into the footwell rather than out towards you. Sit in the driver’s seat, look down and slightly to one side towards the pedals, and you will see the trapezoidal 16-pin connector once your eyes drop below the level of the steering wheel. It is easy to spot but sits low, so you may need to bend down to get a hand to it.
Before You Plug In
- Park on level ground, set the handbrake firmly and put the gearbox in neutral or Park before you lean into the footwell.
- Keep a torch or phone light handy, as the area under the dash is shaded and the socket faces down.
- Turn the ignition off to connect, then switch it to position II (dash lights on, engine not running) so the modules power up.
- Make sure your reader is a standard OBD-II tool; the Micra communicates over CAN, which any modern scanner supports.
How to Access the Connector
- Open the driver’s door and slide the seat back a little to give yourself room in the footwell.
- Crouch by the door sill and look up under the lower dash, towards the fuse cover near the steering column.
- If the small plastic cover is in the way, unclip it gently to expose the fuses and the OBD-II socket beside them.
- Line the plug up the same way round as the 16-pin socket and push it home firmly before switching your tool on.
Tips for Safe Use
- Insert and withdraw the plug straight, without wiggling it, to avoid bending the small pins.
- Unplug any dongle when you finish, as a device left connected can slowly flatten the 12 V battery on a car this size.
- Do not stare at a live-data screen while driving; if you need readings on the move, have a passenger hold the tool.
- Keep the connector free of dust and never force a tool that will not seat, since a bent pin can break the link to the car.
Frequently Asked Questions
Where is the OBD-II port on a 2010-2017 Nissan Micra?
It is under the dashboard on the driver’s side, near the fuse box and roughly below the steering column, facing down into the footwell. Look under the lower dash by the fuse cover and you will find the 16-pin socket within reach.
Do I need to remove a cover to reach the Micra’s OBD-II socket?
Not usually to plug in, but the connector sits alongside the fuses behind the small lower-dash cover. If that panel is in your way, unclip it gently to expose both the fuses and the diagnostic socket, then refit it afterwards.
Will a generic OBD-II reader work on the K13 Micra?
Yes. The 2010-2017 Micra uses the standard 16-pin OBD-II connector and CAN communication, so any generic code reader, Bluetooth adapter or workshop scan tool that supports OBD-II will connect and read its systems.
Why is my Micra’s OBD-II port hard to reach?
The socket faces downwards and sits low under the dash near the pedals, so it is easy to see but awkward to grip. Sliding the seat back and crouching by the door sill gives you a clearer line to it.
