Code B2595 Description

The cornering lamps are activated automatically at vehicle speeds below 25 MPH (40 km/h) when the turn signal/multifunction switch is placed in either the left or right turn positions and/or when the steering angle is changed from the straight-ahead position towards the side the vehicle is turning. When the Body Control Module (BCM) detects that one of these operations has occurred, the BCM responds to the cornering lamp request by applying voltage to cornering lamp control circuit illuminating the appropriate cornering lamp in the area that the vehicle is turning. The cornering lamps are deactivated automatically when the turn signal/multifunction switch is placed in the neutral position and/or the steering angle has returned in the straight-ahead position. The cornering lamps will not operate at vehicle speeds above 25 MPH (40 km/h).
