Hi Keith
I have same situation I didn't have Autel 508 before my first step. My error was 481F8B Lack of connection to FL
Then I both Schrader which apparently had a dead battery I know because I bought Later on Autel 508 and it has shown me a dying sensor .. But I decided to Re-Learn it into the car .. Maybe my mistake.. I did it since it was already in the tyre.. but soon after finishing the successful pairing and OBD witting with Autel it died... Then I used Autel programmable sensor and all went smoothly.. I could see pressure on the dash board..
It used a different from the other three original sensors ID.. it was left in OBD RDC memory after Schrader.. But my happiness didn't last.,.. Because even though I saw pressure across the wheels after I start driving Automatic car Reseat has reported issue : 481F82 OBD error... The electronic of the wheel positioning is unknown (bad wrong electronic of the wheel)
I Asked Autel to help today will give them my Autel 508 Diagnosis reading since they want that rather than obd reading.
I am starting to think it might be an RDC unit failure. And since I had no tool to judge sensors I might unnecessarily start replacing them...
The question is why only one wheel FL was shown as bad? In OBD where temp was 100Deg and pressure 6 Bar
How your situation end up for you ?
