Advanced Diagnostics - DTC U0107: Lost Communication With Throttle Actuator Control Module






General Description
The powertrain control module (PCM) uses the serial signal line for two-way communication with the throttle actuator control module. The PCM 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 PCM. When no serial signals from the throttle actuator control module are received or the serial signals are abnormal for a set time, the PCM detects a malfunction and stores a DTC.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
