  • Downhill Assist Control (DAC)

    Hi all.
    I've a GX auto & was wondering if anyone out there knows if its possible to have Toyota fit the DAC to GX models & what the cost might be.

    I'm getting it serviced in January but thought I'd ask on the Forum before I asked Toyota.

    In theory its the same system as ABS ,but using different software. Let us know how you go.

      White One; apparently there's no computer upgrade to activate the DAC system on the GX model, as the GX doesn't come with DAC sensors, & apparently isn't available as an aftermarket install either... according to the guy I dealt with.

      My 2000 model GU Patrol which I traded for the Tuner never had a DAC feature so going downhills without it in the Tuner shouldn't worry me too much.

        I wonder which sensors they refer to, because my GX has all sorts of wheel speed/acceleration/decel/steering angle sensors that I can see all working

        DAC works well, but 1st low and tapping the brakes when required is just as effective.

              Guys, if you're concerned about controlling your downhill speed, you have a cruise control . Just switch on the cruise control and set the speed you wish to move downhill at . The cruise control will slow the vehicle down if it exceeds the selected speed.
              Cheers.

                Cruise control does not work at speeds below 40km/h.

                DAC operates below 30km/h in H4 or L4 only.

                Cruise control will not operate the braking system either unfortunately.
