how to check mitsubishi error code

To check and retrieve error codes from a Mitsubishi vehicle’s onboard diagnostic system, you will need an OBD-II (On-Board Diagnostics II) scanner or code reader. These devices are commonly available and can be purchased online or at auto parts stores. Here are the steps to check Mitsubishi error codes:

  1. Locate the OBD-II Port:
    • The OBD-II port in a Mitsubishi vehicle is typically located under the dashboard on the driver’s side. It is a 16-pin connector, and you may need to kneel down or use a flashlight to find it.
  2. Turn Off the Vehicle:
    • Ensure the vehicle is turned off before proceeding.
  3. Plug in the OBD-II Scanner:
    • Take your OBD-II scanner or code reader and plug it into the OBD-II port. The device should securely connect to the port.
  4. Turn On the Ignition:
    • In some cases, you may need to turn the ignition key to the “On” position without starting the engine. Refer to your scanner’s instructions for any specific requirements.
  5. Follow Scanner Instructions:
    • Once the scanner is connected and the ignition is on, the device should power on and display a menu or prompt. Follow the on-screen instructions provided by the scanner.
  6. Retrieve Error Codes:
    • Select the option to “Read Codes” or “Retrieve Codes” from the scanner’s menu. The scanner will communicate with the vehicle’s onboard computer and retrieve any error codes stored in the system.
  7. Record the Error Codes:
    • The scanner will display one or more error codes, often in the format “P0XXX” (e.g., P0420 for a catalytic converter issue). Write down or take a picture of the error codes for reference.
  8. Interpret the Error Codes:
    • To understand the meaning of the error codes, you can refer to a repair manual for your specific Mitsubishi vehicle or use online resources. Many websites and forums provide code definitions and potential causes for common OBD-II error codes.
  9. Address the Issues:
    • Once you’ve identified the error codes and their meanings, you can take appropriate action to address the underlying issues. This may involve vehicle repairs, maintenance, or seeking professional assistance from a mechanic.
  10. Clear the Error Codes (Optional):
    • After addressing the issues, you can use the scanner to clear the error codes if desired. This step is optional, but it can be helpful to verify that the issue has been resolved. Follow the scanner’s instructions to clear the codes.
  11. Disconnect the Scanner:
    • Once you’ve finished checking and addressing the error codes, safely disconnect the OBD-II scanner from the port.

Please note that OBD-II error codes provide a starting point for diagnosing vehicle issues, but they do not always pinpoint the exact problem. If you’re unsure about the meaning of a code or how to address a particular issue, it’s advisable to consult a qualified mechanic or automotive technician for assistance. Additionally, keep in mind that newer Mitsubishi vehicles may use more advanced diagnostic systems, so refer to your vehicle’s manual for specific guidance.
