I did the RF hub unlock/reset with my pin. I set it for 45psi but it shows 63psi max as the result. So I put 63psi, 80psi, 58psi and none of them make the warning going away
Do you have a 2500/3500? What year do you have?
You are selecting BCM, active diagnostics, then update pressure thresholds correct? The process was slightly different for my 2012 and it took me a couple tries. On my 2012 the light went of immediately once the BCM accepted the changes, but with other years it may take some time or driving around for few miles for the light to go away.
If you have a 2500/3500 with the light load button on your panel... Look at: BCM, active diagnostics, car configuration change, select option, then scroll down to vehicle config 4. In the vehicle config 4 options there are 4 settings for max load and light load settings.
I'll wait to hear what year/model before I go off more on the max vs. light load in case you don't have that option.
