Forscan Help with 2020 ACC

[Cornwallis]

Does anyone know how to disable ACC and Pre Collision Avoidance on a 2020 using Forscan? There’s another thread on here about all the issues people have with ACC and I’m one of them. I’d really like the cruise to just work in it’s standard form but I can’t even access that option at the moment because my Pre Collision Assist keeps throwing an error and cancels out any type of cruise control adjustment I make.

I just want Pre Collision Avoidance and ACC to be non-functional and not throw errors.

Also I did search and found some Forscan changes one member mentioned but it just cause a ton of errors on my truck. I’ve included the post below. These changes caused errors in every module that I attempted to clear but continuously returned as well as a wrench on the dashboard.



“Livnitup helped me shutoff my Adaptive Cruise after a run in with a Deer. You will need to unhook the sensor to get rid of the warning messages fully after these FORSCAN changes. I then was able to use regular cruise control.

Barry, if you change the following values it should remove any Adaptive Cruise Control and Forward Collision Warning from the truck
BCM 726-13-01 xxx8 2xxx xxxx
IPC 720-01-01 xCxx xxxx xxxx
IPC 720-01-02 xxxx 0xxx
IPC 720-04-01 Cxxx xxxx xxxx
ABS 760-03-01 4xxx xx

Clear all DTC's after the changes in FORSCAN“

Reviving an old thread. Still need some help with this. So do I need to unplug the sensor first and then enter the codes into forscan? And how do I clear the DTC’s? With forscan as well?

I'm curious about this as well

Have not had this problem, but yes, you can both pull and clear DTC with FORSCAN.
