CONDITION# 1.3
On vehicles equipped with reverse automatic braking (RAB), a red area
appears in backup camera display:
CAUSE:
If a customer states they see a red box or area in their backup camera display, the system is
most likely operating as designed. Always perform a visual check of the sensors on the rear bumper
first. If any of the sensors are covered over or obstructed by ice and / or snow, the RAB system may
not function properly and the red area shown in the example photo below will most likely appear.
RECOMMENDATION:
When this condition occurs, the RAB system is unable to properly
differentiate between what really is an obstacle and what is not. In the image below, the sensor is iced
over and the red area is displayed with no obstacle present. The Owner’s Manual provides a list of
other potential causes for this condition to occur.
