Mitsubishis require more than just a jumper wire and a check engine light. This vehicle requires use of a multi-meter. The meter will act as your jumper wire within the diagnostic plug. The diagnostic plug is located on the right-hand side of the fuse box and the two pins that will need to be jumped with the meter are the number 12 and 1 pins. With the meter on the voltage setting and the car in the "ON" position, the code could be read in short and long bursts of voltage sent across the meter. Long bursts of voltage spikes signify digits of 10 and short spikes represent digits of one. Codes can be read with a digital volt/ohm meter but an analog meter is much easier to read.
