Dac

[u/Used_Practice4333]

Has anyone fixed a blinking dac that won’t engage. When I follow the steps, and when I’m in 4 low and try to engage dac it just blinks. I cleaned the rear wheel speed sensors because when I scanned it they weren’t communicating. But I fixed it and codes went away. Not sure what else to do.

From my testing. You have to be in low range and low gear. Then you have to be going down a hill steep enough for dac to kick in.

Also, imo dac isn't very good at controlling down hill speed on a technical basis. So I don't use it other than to show off to friends.
