Code U2010 Ford Description

The Body Control Module (BCM) supplies voltage to all non-networked illumination sources through 1 of 3 circuits.

The Diagnostic Trouble Code (DTC) will set in continuous memory and on-demand when the BCM detects an excessive or a lower than expected current draw from a switch illumination circuit.
