I'm looking for a dongle that plugs into the OBD2 port, sends info to a window 10 computer (for example a laptop computer) via bluetooth connection, or usb connection (I'd like to keep wifi open) and reports not only engine codes, but also the air conditioner codes. Those are P0530 refrigerant pressure sensor circuit malfunction; P0531 refrigerator pressure sensor circuit range/performance (whatever that means); P0532 pressure sensor circuit low voltage; P0533 pressure sensor circuit high voltage (does that mean that the voltage is too high?); and P0534 refrigerant charge loss. ABS system codes would be nice too.

The advertisements for the various OBD2 dongles are rarely very clear as to what the dongle will report. They will say "reports more than just engine codes," and reports codes for[list of car makes]. They don't specifically say "reports AC codes".

So if anyone has bought one of these and you know that it reports the aC codes, please let me know! Thank you.

the $10-15 US dongles typically just report engine codes. I think I'd probably have to shell out at least $50 for something that also reports AC codes.
