2019 Denali 6.2 AFM

[22’s]

Just bought a 2019 Sierra Denali last night. Didn’t notice and indicator of it going into AFM mode like it did on my 14 Silverado. Does the 6.2 have AFM?

if it does, does anyone know if the range AFM disabler I had in my 14 Silverado 5.3 work in my 19 Denali 6.2?

The 6.2 in the Denali has DFM. It can shut down as many as 6-7 cylinders. And GM removed the indicator.

Call Range.  They can reprogram it for the 2019.  They will not guarantee it though for the 10 speed.
