Mitsubishi Galant OBD1 check engine light reading and erasing the code

Reading and erasing the Mitsubishi Galant’s OBD 1 check engine light

Good day, my friend. Today I have another tutorial just for you. I’ve prepared a tutorial on how to read and reset the check engine light on the Mitsubishi Galant even without the help of an OBD diagnostic scanner. This tutorial is only applicable to the following model years: 1997–1997–1998–1999–2000–2001–2002–2003. Please follow my tutorial below.

 

RETRIEVING THE GALANT OBD CODES

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

RESETTING AND ERASING THE CHECK ENGINE OF MITSUBISHI GALANT

  • Ensure ignition switched OFF.
  • Disconnect battery earth lead.
  • Wait 15 seconds.
  • Reconnect battery earth lead.
  • Repeat checking procedure to ensure no data remains in ECM fault memory.

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