Good afternoon,
Is it attached to anything? Looks like it is just laying there.

The check burns, self-diagnosis does not work. that is, if you close A and B then the check will not burn at all and the cooler will spin and nothing else happens.

Do you mean the engine will not start?
Do you mean the ECM will not respond to show codes?

Yeah, I mean, the self-diagnosis doesn't work.

Okay, sorry.
If you jump the 2 pins and it will not flash codes at the check engine light, that indicates a bad ECM. You will need to replace it.
