How to Read and Clear OBD1 Check engine DTC codes on a Mitsubishi Lancer 1992-2003 vehicle without using an OBD scanner

This is another tutorial on the Mitsubishi OBD1. This is all about the Mitsubishi Lancer and how to read and erase the diagnostic trouble code without using the OBD Diagnostic Scanner. In this blogpost, there are 2 separate tutorials: one for the Mitsubishi Lancer from 1992, 1993, 1994, 1995 and1996 because this model uses the OBD1–12 pin DLC connector, and another for the Mitsubishi Lancer model from 1996, 1997, 1998, 1999, 2000, 2001, 2002 and 2003 because this Lancer model uses the OBD–2 socket or the 16 pin data link connector.

Reading Trouble Code Mitsubishi Lancer 1992-1996 Model

You can read the trouble code for this model of Mitsubishi Lancer by using the Multimeter. Please follow the instruction below.

STEP 1

  • Make sure the engine is OFF.

STEP 2

  • Locate the Data Link Connector. See image below for your reference.
  • Possible Location:
      • Under the drivers side dash panel.
      • In or next to the fusebox under the dash panel.
      • Inside or below the glovebox.

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 voltmeter 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.

NOTE:

  • If Multimeter needle deflects rapidly backwards and forwards: This indicates a normal condition with no faults found.
  • If Multimeter needle deflects and remains forwards (high voltage): This indicates a suspected fault with the engine control module (ECM).

 

 

STEP 6

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

Reading Trouble Code Mitsubishi Lancer 1996-2003 Model

Trouble codes are displayed by the malfunction indicator lamp (MIL). Read the check engine or the idiot light flashing in your car dashboard.

STEP 1

  • Make sure the ignition and engine is OFF.

STEP 2

  • Located the 16 pin OBD2 Data Link Connector.

STEP 2

  • Bridge data link connector (DLC) terminal 1 and earth. (Bridge the Terminal 1 and ground it to the metal body of the car.)

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 ‘units’ of the trouble code.
  • A short pause separates each flash.
  • A long pause separates each trouble code.
  • For example: Trouble code 12 displayed.
