TMPS and Hill Assist Control

[mikmabz]

Last night while I was waiting for the train to pass by I decided to try the hill-assist control. I pressed the brake pedal hard and the vsc light blinked indicating that the HAC is working. After about a minute or so I let go of my foot off the brake pedal and *the HAC did work but as soon as I stepped on the gas the TPMS light went off! I wonder if it was just a mere coincidence?!*

This morning, I checked all the tires including the spare, the pressures were 33, 34, and 34.5 psi. There is not much of a difference, eh? But anyway, I added air to all the tires including the spare. All tires are now at 35 psi and after a minute or so the TPMS light turned off. I am going to try the HAC again tonight after work and see if it triggers the TPMS light again. Anybody here experienced this before? *Thanks in advance!
