Understanding the OBD2 pinout for your Mitsubishi vehicle is crucial for effective diagnostics and repairs. The On-Board Diagnostics II (OBD2) system is a standardized system in modern vehicles that allows you to access crucial data about your car’s health and performance. Whether you are a seasoned mechanic or a car enthusiast, knowing the pin configuration of your Mitsubishi’s OBD2 port can significantly simplify troubleshooting and maintenance. This guide provides detailed pinout information for various Mitsubishi models, ensuring you have the knowledge to connect diagnostic tools correctly and interpret the data effectively.
Decoding the Mitsubishi OBD2 Pinout
The OBD2 connector is a 16-pin interface, and each pin is assigned a specific function. While the standard dictates many of these pin assignments, understanding the Mitsubishi-specific configurations is essential. Below are the pinouts for different Mitsubishi models, starting with the Mitsubishi Colt Z25A and then expanding to more recent models like Lancer, Outlander, and ASX.

Key Pin Functions for Colt Z25A:
- Pin 1 (Diagnostic Control): This pin is critical as it often initiates the diagnostic session. It’s essential for establishing communication between your diagnostic tool and the vehicle’s ECU.
- Pins 6 & 14 (CAN Bus): These pins are part of the CAN (Controller Area Network) bus, a standard communication protocol in modern vehicles. CAN bus allows different electronic control units (ECUs) within the car to communicate with each other, and importantly, with external diagnostic tools.
- Pin 16 (+12V): Provides power to the OBD2 interface, ensuring that your diagnostic tool can receive power when connected.
OBD2 Pinout for Mitsubishi Lancer, Outlander, ASX (2008-2015)
For more recent Mitsubishi models like Lancer, Outlander, and ASX produced between 2008 and 2015, the OBD2 pinout remains largely consistent but introduces wire color coding for easier identification, especially when troubleshooting wiring issues.
| Pin | Signal | Description | Wire Colors |
|---|---|---|---|
| Lancer (2008-2015) | |||
| 1-3 | n/c | Not connected | |

Wire Color Significance:
The inclusion of wire colors in this pinout table is particularly helpful when you are physically inspecting or repairing the OBD2 connector wiring. Matching the wire color to the pin function can quickly identify potential breaks or shorts in the wiring. For instance, if you are probing Pin 4 (Chassis Ground), you should expect to see a Black wire in most of these Mitsubishi models.
Mitsubishi OBD-2 Compatibility List
While the pinout provides the physical interface details, the OBD-2 protocol compatibility determines whether your diagnostic tool can communicate with the vehicle’s computer system. Mitsubishi vehicles utilize various OBD-II protocols depending on the model and year of manufacture.

Understanding OBD-II Protocols:
- CAN (Controller Area Network): A high-speed communication protocol widely used in modern vehicles. Mitsubishi models from the mid-2000s onwards increasingly adopted CAN bus.
- ISO 9141 & ISO 14230 (KWP): These are older protocols, often referred to as K-line protocols. Many older Mitsubishi vehicles, especially from the late 1990s to early 2000s, utilize these protocols.
- KWP FAST/SLOW (Keyword Protocol): Variations within the ISO 14230 standard, indicating different data transmission speeds.
Knowing the protocol is as important as the pinout. Your OBD2 diagnostic scanner needs to be compatible with the protocol used by your Mitsubishi vehicle to establish communication successfully.
Conclusion
This guide provides a detailed overview of Mitsubishi OBD2 pinouts and compatibility. By understanding the pin assignments and the OBD-II protocols used in different Mitsubishi models, you can confidently approach vehicle diagnostics and repairs. Always refer to your vehicle’s service manual for the most accurate and model-specific information. Using the correct pinout and a compatible diagnostic tool is the first step towards effectively diagnosing and maintaining your Mitsubishi vehicle.
