|Code U2002 Mercury Description

The parking brake switch has 3 positions; APPLY (pulled up), RELEASE (pushed down), and NEUTRAL. The Anti-Lock Brake System (ABS) Module sends voltage to the parking brake switch and this voltage returns along 1 of 3 circuits. An open, excessive resistance or a short in the parking brake switch circuits or the parking brake switch causes the ABS module to set a Diagnostic Trouble Code (DTC). This DTC sets in continuous memory and on-demand if the test voltage sent to the parking brake switch from the ABS module does not return or returns along an incorrect path.
