Jumper and engine light still on after run the engine
 

Hello guys.

I hear a lot of topics and people mentioned different stuff about ECU problems, engine lights on/off remaining during engine start.

Here is my question.

I jumper the car to to see if there is any error code, I turn the ignition to the first stage, the light turns on, after 10 sec. or so I turn on the engine (the jumper still there in the connector) and the light remain on till I remove the jumper. (the light DOES NOT flash in the whole process in any moment)
My question is, it's normal or ECU problem?

Some people say is ECU other say it's normal so who is right on the end of this obscure question?
