Safety Warning

DTC U0107: Lost Communication With Throttle Actuator Control Module: General Description
The engine control module (ECM)/powertrain control module (PCM) uses the serial signal line for two-way communication with the throttle actuator control module.
The ECM/PCM transmits the accelerator pedal position signal to the throttle actuator module, and the throttle actuator control module transmits the actual throttle valve position signal, or a malfunction signal, etc., to the ECM/PCM 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/PCM detects a malfunction and a DTC is stored.
