U0107 CHEVROLET 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 no only a good circuit integrity, but also sufficient system voltage. This diagnostic test monitors de accuracy od the serial data transmitted between the TAC module and the PCM.
