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.
