One of the guys here at work has the above truck, 2010, 2500, 50K on it, with the 5.7 v8. His tire monitor displays "pressure Low". It shows 58, & 59 psi on the front, and 60 psi on both rears. The two rears are flashing, not the fronts. I scanned it with my Verus, and found only one Active Code C0077-00, Low Tire Pressure. I looked at the door and adjusted the rears to 65, and then 70. I watched the dash, and my scanner and the pressures adjusted ok. When lowering the pressure the left rear is slow to drop, but rises the same as the right rear. i tried to clear the code, but it will not clear. Also tried to turn on and off the light / heavy switch, but it tells me it cann not change to light untill the pressures are adjusted. Any thoughts??? Thanks in advance, Chris

 

1- inflate tires to higher of the values from the sticker

2- drive it until the low pressure warning resets

3- hit the light load button & then you can adjust tire pressures to lower psi

 

Fronts at 60. Backs at 70. Drive till light goes out. Light load button allows backs to be set at 45.
