Circuit/System Description

The ISRVM and rearview camera image display module requires a B+ signal to enable the rear vision system. This signal is provided by the park/neutral position (PNP) switch (automatic transmission) or backup lamp switch (manual transmission) when placing the transmission in reverse. When the transmission is in the reverse, the rearview camera image display module will supply the camera with a regulated 12-volt power source and ground. The LCD display will deploy and remain deployed until the transmission is moved out of the reverse position. Once the transmission is moved out of the reverse position the display will retract. Anything preventing the display from fully extending will cause the display to retract. A shielded video signal circuit will transfer the video signal through the rearview camera image display module to the ISRVM display.
