Where is the OBD-II Port in your Mitsubishi?
Reviewed/Verified by:
On nearly every Mitsubishi the OBD-II port sits under the dashboard on the driver’s side, just left of the steering column and above the pedals. Models built before OBD2 arrived use a smaller 12 pin diagnostic connector instead, usually under the dash or near the fuse box, which needs a different adapter entirely.
At a Glance
- Where it is: under the dashboard on the driver’s side, to the left of the steering column, on most Mitsubishi models.
- Turn the ignition on so the dash lights come on, without starting the engine. Mitsubishi modules will not answer a scanner with the ignition off.
- What a basic reader misses: it sees engine emissions codes only, not ABS, airbag, transmission or body faults.
- For those systems, use a scanner that supports Mitsubishi modules (see below).
After You Connect: What to Do With the Codes
- Write down every code and the freeze frame data before you clear anything.
- Look up what each code means; our guide to resetting the Mitsubishi check engine light covers clearing them once the fault is fixed.
- If the ASC or traction light is on as well, read what the ASC service required warning means; it is often triggered by an engine fault.
- A code that returns right after clearing means the fault is still there, so fix the cause first.
What to do next: Mitsubishi owners usually need more than the engine module
This page gets you to the connector. What matters next is how much of the car your tool can actually see, because the complaints Mitsubishi owners bring are frequently logged somewhere other than the engine computer.
- Scan the transmission, brake and body modules as well. On the CVT equipped cars in particular, the useful codes are not in the engine controller.
- Watch live data before replacing a sensor. A reading that looks right at idle and goes wrong under load is the common pattern here and a stored code will not show it.
- Rule out battery and charging problems first. It costs nothing and explains a good number of multi module faults.
- Confirm whether the repair needs a reset at the end before you begin, rather than discovering it with the car in pieces.
The YOUCANIC UCAN-II Pro reads the full module list on these vehicles and performs the available service functions, with a seven day rental if you need it once. Coverage and function support vary by model and year, so email support with your VIN and the job you intend to do and we will confirm it first.

When you do not need a scan tool
Reading a single engine code, or fitting a tracker or logger. Both are finished the moment you find the port.
Frequently Asked Questions
Where was the diagnostic port on older Mitsubishis?
Mitsubishis built before OBD2 used a smaller 12 pin diagnostic connector, usually under the dash or near the fuse box. A standard OBD2 scanner needs an adapter for those cars.
Will a cheap Bluetooth OBD2 adapter work on my Mitsubishi?
Yes, for engine and emissions codes and basic live data. It will not read ABS, airbag, CVT or body module codes, which need a scanner with Mitsubishi coverage.
Can I drive with the scanner plugged in?
You can for live data, but route the cable so it cannot catch your feet or the pedals, and unplug small dongles if the car will sit for days, since some drain the battery.

Where is the OBD-II Port Located in a Mitsubishi?
On most Mitsubishi models, the OBD-II port is under the dashboard on the driver’s side, to the left of the steering column. The video below shows where to look.
The OBD-II port on a Mitsubishi vehicle is under the dashboard on the driver’s side.
Slide under the dashboard on the driver’s side and look above the brake pedal. You will see the trapezoid-shaped OBD2 port. The OBD-II port (OBD2) can diagnose engine, ABS, traction, transmission, and Mitsubishi problems.
All Mitsubishi vehicles sold in the US since 1996 and Europe since 2000 have the OBD2 port under the dash. This guide applies to all Mitsubishi models, including Lancer, Eclipse, Outlander, Mirage, Galant, Montero, Pajero, etc.
Troubleshooting with YOUCANIC UCAN-II Pro
The YOUCANIC UCAN-II Pro reads and clears fault codes in the modules of supported Mitsubishi vehicles. It can also perform bi-directional tests, maintenance and repair resets, and many more.
Scanner plugged in but not connecting?
Turn the ignition to the ON position so the dashboard lights come on without starting the engine. Mitsubishi control modules will not answer a scan tool with the ignition fully off, and this is the single most common reason a tool reports no communication on a car that is otherwise fine.
Push the connector all the way in until it seats. A half seated plug will light up the scanner from the port’s power pins while failing to pass any data, which looks like a dead car but is a two second fix.
If the scanner gets no power at all, check the fuse feeding the diagnostic socket before assuming the port is broken. On most Mitsubishi models it shares a circuit with the accessory or cigarette lighter socket, so if that socket is also dead you have found the fault without opening anything.
What a basic code reader will miss
A generic OBD2 reader only has access to emissions related engine data. On a Mitsubishi that leaves out the ABS, airbag (SRS), transmission, ASC stability control and body control modules, which is where most warning lights actually originate. It is why a car with a lit dashboard can still read as having no codes stored.
Reaching those systems needs a full system scanner that supports Mitsubishi specific protocols rather than generic OBD2 alone.
