DTC U0107: Lost Communication With Throttle Actuator Control Module: General Description

The engine control module (ECM) uses the serial signal line to exchange pulsing signals with the throttle actuator control module.

The ECM transmits the accelerator pedal position signal, etc. to the throttle actuator module, and the throttle actuator control module transmits the actual throttle valve position signal, a malfunction signal, etc. to the ECM via this line.

When no serial signals from the throttle actuator control module are received or the serial signals are abnormal for more than a set time, the ECM detects a malfunction and a DTC is stored.
