ECM (Engine Control Modulde) Diagnostication
ECM has diagnosis details to solve general problems.
The malfunctions are indicated via engine warning lamp on
the gauge board.

components so that the problems can be solved as quickly
as possible.

position. The engine does not spin at this mement.

ECM Fault Code
Fault code is displayed after self diagnosis and when there
is a fault.
Engine warning lamp will flicker when fault code occurs and
the info will be stored at ECM.
Oxygen sensor and engine control related malfunctions are
constantly indicated until the problem is solved through self
diagnosis.
If the lamp is flickering and if the problem is persisted, the
system will continue to appear.
General problems will automatically dissapear in about 30
seconds of driving mode, but engine related problems will
not be removed automatically.
If the sensor is experiencing difficulty, ECM will operate
according to stored values.
Every self diagnosis of ECM will be obtained while the
vehicle is driven fault-less.
If more than one fault code is detected, less fault codes will
be displayed first and will continue to examine until the
malfunction is no longer detected.
fault codes can be confirmed with engine warning lamp and
Faulty Diagnosis device(SCAN-200).
