How To Read And Clear The Check Engine Light On A Mitsubishi Colt Without An OBD Scan Tool

Hello, my friend. Do you have a Mitsubishi Colt that has a check engine light on it? If your Mitsubishi Colt is from the 1992–2003 model year, you can use this tutorial to retrieve the code behind the check engine light. This tutorial is called “idiot-light reading.” But before you can get the code, there are some important requirements to make the check engine light flash. Please follow my instructions below to guide you through all the steps.

There are two separate tutorials for the Mitsubishi Colt 1992–1996 and 1996–2003 models. The 1992 model uses the OBD1 12-pin DLC, and the 1996 model uses the OBD2 16-pin socket.

In this blog post, I also included the list of DTCs and the procedure on how to clear, erase, or reset the trouble code on your computer box.

Mitsubishi Colt 1992-1996 Procedure

STEP 1

  • Make sure the engine is OFF.

STEP 2

  • Locate OBD DLC 12 Pins Data Link Connector. See image below for your reference.

STEP 3

  • Connect analogue Multi Tester between data link connector (DLC) terminals 1 and 12. Set the the Tester to DC 2.5 or 10 Volts.

STEP 4

  • Turn the Ignition ON.

STEP 5

  • Count Multimeter needle deflections. Compare with trouble code table.
  • Each trouble code consists of two groups of one or more needle deflections.
  • Long deflections indicate the ‘TENS’ of the trouble code .
  • Short deflections indicate the ‘ONE’ of the trouble code.
  • A short pause separates each deflection.
  • A long pause separates each trouble code.
  • For example: Trouble code 12 displayed.

STEP 6

  • Write the code then check the corresponding code meaning below.

Mitsubishi Colt 1996-2003 Procedure

STEP 1

  • Make sure the ignition and engine is OFF.

STEP 2

  • Located the 16 pin OBD2 Data Link Connector.

STEP 3

  • Switch the Ignition to On. Don’t start the engine.

STEP 4

  • Count MIL flashes. Note trouble codes. Compare with trouble code table.
  • Each trouble code consists of two groups of one or more flashes.
  • Long flashes indicate the ‘TENs’ of the trouble code.
  • Short flashes indicate the ‘ONE’ of the trouble code.
  • A short pause separates each flash.
  • A long pause separates each trouble code.
  • For example: Trouble code 12 displayed.
