I am a noob to the forum. We are working on my brother's 2018 Jeep Grand Cherokee, and need to get the control access to the air suspension. Wondering if anyone has used the Harbor Freight Icon T7 scanner to work on their Jeep for diagnosis and controls. Want to get him this scanner if it will help him out. He's been having a rough go the last several months, and I am trying to help him where I can. Any help would be great. Thanks!
