The RVC system display in the
rearview mirror may turn off or not
appear as expected due to one of
the following conditions. If this
occurs the left indicator light on the
mirror will flash.
A slow flash may indicate a loss
of video signal, or no video
signal present during the reverse
cycle.
A fast flash may indicate that
the display has been on for the
maximum allowable time during
a reverse cycle, or the display
has reached an Over
Temperature limit.
The fast flash conditions are
used to protect the video
device from high temperature
conditions. Once conditions
return to normal the device will
reset and the green indicator will
stop flashing.

the display will be blank and the
indicator will flash while the vehicle
