the enhanced obd2 would work on my 2004 chevy venture but bi-directional capability won't work almost at all and the gauge for TPS won't give any signal , i thought it wasn't working and was about to change it then checked it with another scanner and it was working , fix please would pay $ more for extra features on different manufacturers
Bi-directional controls for 2004 GMC envoy do work, but they are all labeled incorrectly. For example, when I try to toggle the fan relay, it cranks the engine over for a brief 1-2 seconds.
Also, there was another I found that turned the fuel pump on, but was labeled something entirely different. I was really hoping to have bi-directional control over the secondary AIR system but that did not function either.
