Hello and happy new year !
As the topic says, I was watching a topic in the “Step By Step section” and there is a topic about “How to Figure out your Check Engine Light code“ and inside it tells like a self diagnostics of the ECU “Turn the ignition switch to ON ( II ), Then turn it back to off three times. “ Then I went to my car and I notice that the Check Engine light doesn’t turn ON!!! I think that the last owner had a problem and he disconnected the light, so: What can I do to fix it? Where could it be disconnected? Any help I would really appreciate!

Thanks

if it dosnt come on, it means you havnt thrown a code since the last time your ecu reset

What I mean is that the light doesnt turn on at any time. For example: When u turn on the car, all the lights in the dash turns on exept the Check Engine. What I think is that someone for one reason disconnected it. Or, how can I make sure if it is connected?

Does anybody have his prelude near to make me a favor and go and see if the check engine light turns on before turning on the car?

hmm that's weird. short your service connector pins and see if it goes on solid. as far as i know most of the cars have the CEL on during the self check

How do I do that?

i think on your car the conector is behind the center console. it should be a blue conector, and the short it with a paper clip and put the key on the on position.
