I have a question about bi-directional OBDII scan tools for a 2006 GMC Yukon Denali. I installed a new throttle body and swapped on some new 2021 GMC wheels with good TPMS sensors. I researched scanners extensively and purchased a TOPDON AD500. It wouldn’t let me change anything and their tech support told me that my vehicle wasn’t compatible even though their tech documentation said it was. I returned it and purchased a Foxwell NT530 for GM and it wouldn’t let me change anything either. Their support sucks as you have to send emails to China but I was told my vehicle isn’t compatible, again, even though their tech documentation said that it is. Has any one else experienced this? I have asked for a reason and searched but I can’t find anything. Is there a reason for this that I’m just not aware of? Much thanks in advance
