Mitsubishi Code Retrieval
Diagnostic Trouble Code
Interpretation
Electronic Control Injection
With the ignition switch in the On position, the system will indicate any
trouble codes on the voltmeter by deflecting the pointer to the 12 volt
reading and then to the zero voltage reading within 0.8 second. If this
action was repeated three times, this would indicate a code three is present
in the ECU memory. If more than one code is stored in the memory, there will
be a two second pause between code signals. If no codes are present in the
memory, the voltmeter will have a constant reading of 12 volts.
Multi-Port Injection
1986-88
With the ignition switch in the On position, the system will indicate
any trouble codes in memory by deflecting a voltmeter pointer. After three
seconds of a steady voltage reading, the voltmeter will indicate the five
digit trouble code. The trouble code digits consists of zeros and ones. A
voltage reading time of 1/2 second will indicate zero, while a voltage
reading time of 1/2 seconds will indicate one. A steady voltage reading
for 1/2 second, followed by a no voltage reading, followed by a voltage
reading for 1/2 seconds, followed by a no voltage reading, followed by a
voltage reading for 1/2 second, followed by a no voltage reading, followed
by a voltage reading for 1/2 second, followed by a no voltage reading,
followed by a voltage reading for 1/2 second, would indicate trouble code
01000.
1988-93
With the ignition switch in the On position, the system will indicate
any trouble codes on the voltmeter by deflecting the pointer to the 12
volt reading and then to the zero voltage reading within 0.8 second. If
this action was repeated three times, this would indicate a code three is
present in the ECU memory. If more than one code is stored in the memory,
there will be a two second pause between code signals. If no codes are
present in the memory, the voltmeter will have a constant reading of 12
volts.
1994-95
Diamante, Expo, Galant, Mirage, Montero DOHC & SOHC,
Precis, Truck, 3000GT & 1994 Eclipse
With the ignition switch in the On position, the system will indicate
any trouble codes on the voltmeter by deflecting the pointer to the 12
volt reading and then to the 0 voltage reading. The tens digit of the
trouble code will be indicated by the voltmeter pointer indicating voltage
for 1/2 seconds. The units digit of the trouble code will be indicated by
the voltmeter pointer indicating voltage for 1/2 second. A voltage reading
for 1/2 seconds, followed by a no voltage reading, followed by a voltage
reading for 1/2 second, followed by a no voltage reading, followed by a
voltage reading for 1/2 second, would indicate trouble code 12.
1995 Eclipse
Count the number of time the MIL flashes on and off. There is a slight
pause between the flashes representing the first and second digits of the
code. Longer pauses (approx. four seconds) separate individual trouble
codes.
Clearing Diagnostic Trouble Codes
Electronic Control Injection
After repairs have been completed, disconnect the battery ground cable
for approximately one minute.
Multi-Port Injection
After repairs have been completed, disconnect the battery ground cable
for approximately 10 seconds.
