The OBD2 (On-Board Diagnostics) port in your 2002 Mitsubishi Eclipse GT Spyder is a crucial interface for diagnosing and troubleshooting vehicle issues. Understanding its pinout, or the arrangement of its connector pins, is essential for effective communication with your car’s computer. This guide provides a detailed breakdown of the OBD2 pinout for your specific model, enabling you to interpret diagnostic trouble codes (DTCs) and monitor various vehicle parameters.
Understanding the OBD2 Port in Your 2002 Mitsubishi Eclipse GT Spyder
The OBD2 standard, implemented in most vehicles manufactured after 1996, mandates a standardized 16-pin connector located within the driver’s reach. This connector, known as the DLC (Data Link Connector), facilitates access to the vehicle’s onboard computer systems. For the 2002 Mitsubishi Eclipse GT Spyder, the OBD2 protocol utilized is ISO 14230-4 (also known as KWP2000), as indicated in the compatibility list below. This protocol defines the communication method used between the scan tool and the vehicle’s ECU.

While the standard OBD2 connector has 16 pins, not all are used in every vehicle. Some pins are dedicated to specific manufacturers or communication protocols. Here’s a breakdown of the relevant pins for your 2002 Mitsubishi Eclipse GT Spyder:
| Pin | Signal | Description |
|---|---|---|
| 4 | CGND | Chassis Ground |
| 5 | SGND | Signal Ground |
| 7 | K-Line | ISO 9141-2 Communication Line |
| 16 | +12V | Battery Power |
Important Note: Pins 1, 2, 3, 6, 8, 9, 10, 11, 12, 13, 14, and 15 are likely not used in your 2002 Mitsubishi Eclipse GT Spyder. Always double-check with a reliable wiring diagram for your specific vehicle year and model before connecting any diagnostic equipment.

This table lists the OBD-2 protocols for various Mitsubishi models, including the Eclipse Spyder. Note that it’s not exhaustive.
| Model | Year | OBD-2 Protocol |
|---|---|---|
| Mitsubishi Eclipse Spyder | 2002 | ISO 14230-4, ISO 9141-2 |
Locating the OBD2 Port
The OBD2 port in the 2002 Mitsubishi Eclipse GT Spyder is typically located under the dashboard on the driver’s side, often near the steering column or the fuse box. Consult your owner’s manual for the precise location if you’re having trouble finding it.
Utilizing the OBD2 Pinout Information
Knowing the pinout allows you to use a variety of diagnostic tools, from basic code readers to advanced scan tools, to:
- Retrieve Diagnostic Trouble Codes (DTCs): Identify the source of malfunctions triggering the “Check Engine” light.
- Monitor Live Data: Observe real-time sensor readings such as engine speed, coolant temperature, and oxygen sensor voltage.
- Perform Actuator Tests: Command various components, such as fuel injectors or solenoids, to verify their functionality.
This understanding of the 2002 Mitsubishi Eclipse GT Spyder’s OBD2 pinout empowers you to take a more proactive approach to vehicle maintenance and troubleshooting.
