I cannot get GM PIDs to load for my 1996 GMC 1500. I used my existing Chinese Bluetooth dongle with no success so I just purchased a OBDLink MX Bluetooth dongle and it still will not load PIDs. Why can I not get this to work? I tried using all three addresses that appear when I try connecting (all of them say 10) and I tried scanned all PIDs and auto scan pre-selected PIDs. Nothing will work no matter what combination.
Hi. did you figure this out. I have same issue on a 97 5.7 vortec. Cant get any pid's. says 10 and then when scans says none supported. I can use the generic but I'm looking to set timming and need the cam retard pid.
I also bought this to set my cam retar and I keep getting pids is not supported this is the only reason why I purchased this app I actually ordered the recommended Bluetooth adapter from this app 1997 k1500 350 vortec
