Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Display Screen Module (DSM)
| Refer to COMPONENT INDEX . |
The DSM touch screen display uses a coordinate system to determine what soft key touches have been selected in the RVC system menu. The DSM uses these coordinates to send the enable or disable signal as well as which modes to display to the RVC.
The DSM provides power over the LVDS to the RVC when the BCM reports that the ignition is in RUN or START.
The DSM is in automatic display mode when the ignition is in RUN and the gear shift lever is in R everse and will display the RVC image. Once the DSM receives the signal that the vehicle is no longer in R everse, the DSM automatically switches back to the non-camera display mode.
The DSM is also responsible for gating several CAN messages to LVDS for the RVC to use.
The DSM is responsible for implementing a warning text overlay display to the driver for various conditions.
