CAUTION: When performing certain testing procedures, it may be that additional fault codes are generated. Care must be taken to ensure that the codes generated during testing do not mislead the inspector.
Connect the fault code reader (2) to the self-diagnosis connector (3).
Connect power to the device from the cigarette lighter (1).
Use the trouble code reader for the following purposes in strict accordance with the instructions of the device manufacturers:
- reading fault codes;
- erasing fault codes.
After checking the parts, as well as after repairs that involve removing or replacing parts of the engine management system, you should always erase the codes.
Use a trouble code reader to query the electronic control module for trouble codes, or read the codes manually as described above.
There are codes in memory
If one or more fault codes are detected, use the tables below to determine the meaning of the fault code.
(The material was borrowed from the website www.mitsubishiman.ru)
If multiple codes are displayed, look for a common symptom, such as a fault in the power or ground circuits.
Once the fault has been corrected, clear the codes and run the engine under various conditions to determine if the problem has gone away.
1Check the electronic control module for fault codes again. Repeat the above procedures if the codes are still stored.
There are no codes in memory
When there are problems with engine operation, but there are no codes in the memory of the electronic control module, the malfunction is not included in the parameters provided by the self-diagnostic system.
If the symptoms point to a specific part, replace the faulty part with a working one.
