EGR, cannister purge. For the trans, it only controls the torque converter clutch.

ABS/ASR has some input to the ECM, from what I understand there are some tables that control the amount of spark taken out when the ASR is active.

The CCM, ABS/ASR, HVAC, and ECM all communicate on the same serial line.
