How to Read and Clear the CHECK ENGINE Mitsubishi Montero/Pajero/Shogun without using the OBD DIAGNOSTIC SCANNER
This is my simple tutorial on how to read the meaning behind the Check Engine light on your Mistubishi Montero, Pajero, or Shogun car model. This tutorial is applicable only for the following year models: 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, and 2000. Even though this car model is OBD2, you can still retrieve the trouble code by counting the check engine lights flashing on your dashboard. Please follow my tutorial below to guide you through the process of retrieving the OBD1 codes. Anyway, you can simply get the check engine code by using the OBD diagnostic scanner.
READING THE CHECK ENGINE PROCEDURE
ENGINE PROBLEM: Trouble codes are displayed by the malfunction indicator lamp (MIL).
TRANSMISSION PROBLEM: Trouble codes are displayed by using the AT/fluid temperature warning lamp.
IMMOBILIZER PROBLEM: The immobilizer control module fault memory can only be accessed and erased using diagnostic equipment connected to the data link connector (DLC).
AIRBAG PROBLEM: SRS control module incorporates self-diagnosis function. SRS warning lamp will illuminate if certain faults are recorded. SRS control module fault memory can only be checked using diagnostic equipment connected to the data link connector (DLC).
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.
STEP 5
- Write the code then check the corresponding code description below.

ERASING THE TROUBLE CODE
- 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).
This is all the information you need to know for the guide on OBD1 diagnostics for the Mitsubishi Montero, Shogun, and Pajero. I hope this tutorial helped you resolve your check engine light problems. Thank you very much for visiting my website. -Erwin Salarda.
