Code B1280 2014 GMC Sierra Description

The rear displays are located in the back of the driver and front passenger seats. The rear seatback display screens show video from the disc player.
The seatback displays receive power and ground from the vehicle harness. A discrete control circuit from the disc player is used to control the power state of the displays.

A splitter cable is used to separate the data circuits to each individual display, providing separate information to each display.
