Mitsubishi Trouble Codes OBD1

AD
Step by step guide on how to retrieve Mitsubishi obd1 (1996 and earlier) diagnostic trouble codes.

Difficulty Scale: 2 of 10

Step 1 - To gather troubles codes from the system locate the diagnostic data 12 port connector which is located under the dash by the kick panel on the driver's side.

Step 2 - Use an analog style of voltmeter (sweeper arm) set the voltmeter dial to continuity. Next, insert the positive lead into the number #1 terminal and the black or ground lead into the #12 terminal. Turn the ignition key to the "ON" position and observe the voltmeter needle sweeping from right to left. The first set of sweeps will be the first digit of the code followed by a second set of sweeps which will be the second digit. For example, if the meter sweeps twice and then pauses and then sweeps four more times, the code number would be 24.

Step 3 - To re-start code gathering simply turn the ignition key to the "OFF" position and then turn it back "ON" again. Once the repairs have been made, clear the codes by removing the negative battery cable for two minutes and then reconnect.
