Circuit/System Description

WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

The performance data recorder system can play back recorded events on the info display module. The performance data recorder sends a request to the radio via the video display request signal. If the radio grants the request, the radio sends a command to the info display module via serial data.
