In this model the cable from the trackpad the logic board carries both the trackpad and keyboard signals. So if the trackpad’s interface logic within it is damaged then yes both the trackpads and keyboard signals won’t make it through. This is a common issue when the trackpad has gotten a spill and the liquid has corroded or shorted out the logic.
