Head-Up Display Description and Operation: Speedometer

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The speedometer is shown on the head-up display (HUD) as a 3-digit display. The HUD speedometer is capable of displaying up to 120 mph. The HUD receives a serial data message from the engine control module (ECM) or the powertrain control module (PCM) indicating vehicle speed. If the serial data message from the ECM/PCM is invalid the HUD will use the serial data message from the electronic brake control module (EBCM) instead.
