Clean the BSI Radar Units
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
When mud, dirt, wet snow, leaves, or other foreign material sticks to the side of the rear bumper, the BSI system stops control and indicates that the BSI radar units must be cleaned in the MID. It also turns on the BSI indicator at the same time, and store the DTC(s).
When the obstruction or contamination is removed, the indicator in MID goes off and the BSI system automatically returns to ON.
