I found its PIDS is under MODE 0x21 and PID 0x01, I hope it helps to other peoples.

As the article says, the copies can often misreport what code version they have, so that's of no use in determining what they can or can't do. All that can be extracted from the microcontroller is the machine code that sets up and operates the microcontroller, not the original source code, so modifying it substantially is likely beyond most of the clone ...

I have actually seen an AC compressor on a 5.4 lock up so badly that the engine would no longer start. However, this was after the clutch had gone bad for a long time and the AC was not working at all for a while leading up to this. Also probably not a likely scenario. Most likely, the compressor clutch would stay disengaged if something were to happen to ...

Not the check engine light but on newer cars it may set a code in the Body Control Module, which has to be read with a good quality obd scanner, but there is no light for that since it is non critical and not part of the OBD standard yet.

For diagnosing an engine light or other dash lights you will need a scan tool to read the code and then from there you usually go on to read live data in the relevant control module and the last step is component testing to test the suspected faulty components. After this then repair and retest. When reading a check engine light though you to consider that ...

Many auto parts stores will read the trouble codes for free. They use inexpensive code readers that aren't capable of reading manufacturer-specific codes. But they're free. If you want to work on your car, owning a decent quality scan tool is a very good investment.
