Camera Image Generation

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The front and rear cameras are on any time they receive voltage (when the ignition is on), but a video signal is only generated under certain conditions. When reverse (R) is selected or the camera selection switch is pressed, the IPMA sends an enable request message to the front and rear cameras over coaxial cables via LVDS to turn the video signal output on. When any gear except reverse (R) is selected, the IPMA sends a disable request message to the cameras to turn the video signal off when the vehicle speed reaches 16 km/h (10 mph), and sends an enable request message to turn the video signal on when vehicle speed falls below 8 km/h (5 mph). If the IPMA is not configured properly, some features and views may be inoperative.

The LH and RH side cameras are on and generating a video signal any time they receive voltage from the IPMA. The IPMA sends an enable request message through coaxial cables via LVDS to the LH and RH side cameras when reverse (R) is selected and the vehicle speed is below 8 km/h (5 mph) or the camera selection switch is pressed.
