Hi.
What modules I should be possible to connect by testers on these cars ? My IDS with yeah wrong chinese mongoose cable only looks codes from engine, transmission, hvac, suspension, srs and abs. It doesn't connect to hvac and cats. I do have cats on my car. But I think that no connection to those is because mongoose uses J2345? Recently I bought Foxwell nt530 and that doesn't support x308 at all. But when I connect to the car by XK, nt530 founds lot's of modules and read codes from them. Because Xk is different car.I bet that these modules and codes are false founds as codes can not be removed. And everything works on my car and there is no warning lights.

What is maybe kinda weird is that with IDS I can read live data from bpm and let's say security & locking module but I can not connect to them like let's say engine. I do understand car networking but these cars are new to me.
Is this just user error ?
