EMS(Engine Management System)
HOW TO SHOW THE FAULT CODE
There are two methods to show the Fault codes.
First, the methods to show in engine operation
In engine operation, when there is something wrong in each part of EMS, the MIL keeps light on without the
light on/off function of MIL in order for driver to acknowledge defect. This time, so for checking the fault code,
stop the vehicle and engine, and in the ignition key on, by checking the number of lighting, the fault code can be
verified.(refer to the fault code table)
Second,the ways of indication only turn on the ignition key.
When only ignition key is on and if the defect of each part brings out, the MIL keeps showing
the Fault code of defect part repeatedly in order to give defect information to driver.
If the MILon when engine is working, engine is able to be operated by fail safe. However, in the event that
Injector, Fuel pump, Ignition coil has something wrong, vehicle may not been driven and engine not started
HOW TO READ THE FAULT CODE
The fault codes are showed as 2 digits on the MIL of EMS.
Only one defect code is showed up to prior sequence of defects. This time, that fault code is repeatedly showed.
E.g. ) The Fault code of ISA
If many problems will happened in the EMS parts at the same time only one fault code is displayed by the
priority, however, the ECU is remembers all the fault codes.
After revise the code, remove the memorized fault code by the method of warm up.(5-10)
(Refer to remove the fault codes)
When the vehicle is checked using the diagnosis tool.
- If the vehicle is check using the malfunction diagnosis tool, all fault code check is possible.
