Additional Options (RPOs) Condition 5758378 Some customers may comment on seeing a black screen with red triangle and red camera with a circle and slash through It when vehicle is in Reverse. This condition may be intermittent. Cause The cause of the condition may be that the crimping of the coaxial cable connectors to the cable is causing an excessive resistance that interrupts the video signal and causes the black screen. Correction Note: Verify the Condition, then depending on Model and Year, follow the appropriate repair in the list of Repair Procedures below.
