Isuzu D-max 3.0 2009 port OBDII

An ELM327 device should work for any OBDII vehicle found on the road here in the US. They are very universal.

You'll need to ensure you are getting the right reader for your monitoring device though. There are specific ones for iOS and Android devices. The Bluetooth ones will not work with Apple products. You need one which works on WiFi. The ELM327 devices I've see usually state what they work with, so ensure you check. Whenever you get your device, don't leave it plugged in, as the ones I've seen are "always on" even with the vehicle shut off. So it will drain your battery over time. Also, Torque Lite is a free app which works well on Android devices (not sure what's good for iOS).

The whole point with the OBDII standard is that any standards compliant OBDII reader should be able to read your codes. Now, that's not necessarily all codes as some manufacturers have proprietary readers to access some diagnostics, but you probably can't get one of those and even if you could they cost stupid money so out of reach for the curious.

So it's not about compatibility as much as features. If all you want is to read your codes every once and awhile then the cheapest possible option is a bluetooth OBD reader which will sync to a free app on your phone or tablet. I use one of these myself with Torque Lite and I have no complaints. There are also self-contained units with LCD screens which go from basic functionality up to advanced functions. So buy a reader based on what you want to do.
