My understanding is that you will get a check engine light if you do not install a cancellation module. Did you pay extra to have the ADS system installed? I thought that only the Type S and the Advance package get the ADS system. Everything else (Aspec/Tech/Base) get amplitude reactive dampers which do not change with drive mode.Hi ! I m just about to buy coilover for my 2021 TLX A-Spec AWD , do i need to buy a ADS cancellation module or i can drop the original suspension and wont have any check engine light problem ?
