Pulling the OBD1 CODE of the Mitsubishi Sigma’s Check Engine

Hello, this is Erwin! We have another tutorial. Anyway, this tutorial is almost the same as my other tutorial on Mitsubishi OBD1, but I need to put this tutorial in another blog post because every Mitsubishi OBD1 has a different trouble code. I don’t want to confused you, so I make each tutorial be specific to make it easy to understand.

This tutorial is about how to pull and read the meaning of the code behind the check engine light even without the use of an OBD diagnostic scanner. This tutorial also includes a complete list of OBD1 codes for the Mitsubishi Sigma as well as instructions on how to clear, erase, or reset the check engine trouble code. This tutorial will only work for the following years: 1991, 1992, 1993, 1994, 1995, and 1996.

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.

ERASING CLEARING AND RESETTING THE CHECK ENGINE DTC

  1. Ensure ignition switched OFF.
  2. Disconnect battery earth lead.
  3. Wait 15 seconds.
  4. Reconnect battery earth lead.

WARNING: Disconnecting the battery may erase memory from electronic units (e.g. radio, clock).

That is all the information you need to know on how to read the diagnostic trouble code behind the check light on a Mitsubishi Sigma. I hope this tutorial will be helpful to you. Thank you very much- Erwin Salarda.
