I've been playing around with my OBDLink MX+ and I wrote down some PIDs for 2002 oldsmobile bravada. I think most should work on any 2002-? 4.2L I6 vehicles. Personally, I find the OBDLink app very aesthetically pleasing and OBDLink MX+ could communicate with all of the modules.

Some of the codes I've tested and data that made sense was received. Other PIDs, data was received but didn't make sense or did not receive data at all. Here are the codes:

I think our trucks report all units in imperial then the software translates them to metric. I'm not sure so please correct me
