Throttle Actuator Control Module

Throttle Actuator Control (TAC) module receives inputs from Powertrain Control Module (PCM) through TAC serial data circuits and through driver-controlled inputs. By monitoring cruise control functional switches, cruise control release switch (A/T), cruise control brake switch (M/T), clutch pedal position switch, brakelight switch and throttle pedal position, TAC module commands throttle actuator motor to respond accordingly to maintain set cruising speed.
