When I turn on the ignition switch "check engine" light doesn't illuminates and I wondering if someone can switch it off after re-map the ECU or de-cat the exhuast system ?

I need to know this before i remove the instruments panel to check the bulb's etc

Righto ! I've removed the cluster and found the bulb for the "check engine" light.

But the bulb is a LED's type lamp which is soldered on PCB which cannot tested by using low continuity tester.

So no luck there

But how can someone disabled the light intentionally to hide a problem ?

Please Help Anyone
