U0107 HUMMER Description
The Throttle Actuator Control (TAC) module and the Powertrain Control Module (PCM) communicate via a dedicated serial data circuit. This serial data circuit is separated from other serial data circuits on the vehicle. Accurate transmitting and receiving of serial data require not only good circuit integrity but also sufficient system voltage. This diagnostic test monitors de accuracy of the serial data transmitted between the TAC module and the PCM. The Diagnostic Trouble Code (DTC) U0107 is set when the Powertrain Control Module detects a loss of data or invalid data from the Throttle Actuator Control.
