Hello, I´m Leandro from Argentina.
First of all, sorry for my basic writing.
I´m trying to solve a problem about the check engine light.
Few months ago, when I started the engine, the check engine light has been on (with cold engine). So, I turned the ignition switch off and started it again, resulting that the check engine light turned off.
Some days after, for achieve that the light turn off, I had wait that engine was hot, and then turn off the ignition switch and start it again.
I bridged 2 pins service check connector, but the check engine light responded as if there weren´t issues.
I tried to connect an OBDII scanner, but It was imposible to communicate with the PCM/ECM.
Today, with cold or hot engine, the light always turn on seconds after start the engine.

I Don´t know what to do, I´m so depressed about this.
What could be happen?

Thanks a lot.
