Circuit/System Description
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module and the chassis control module simultaneously control the vehicle performance. During a automatic brake event the electronic brake control module sends a serial data message to the chassis control module. If the chassis control module receives corrupt data from the electronic brake control module, DTC C127F will set in the chassis control module.
