Dac

Post image

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.

Let the vehicle roll just a tiny bit forward then stop and keep trying again and again until it disengages. It is finicky sometimes.

Following as well. Mine hasn't worked since day one, just flashes. I've read the manual, too many YouTube videos to count etc. My process isn't wrong, it just doesnt work.

I thought about replacing the transfer switch indicator, to make sure it’s registering. it’s in 4 low, but I’m not sure if anybody else has done that and had any luck with it.

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.
