Code C1095 Mercury Description

The C1095 diagnostic trouble code (DTC) for Mercury vehicles indicates an ABS Hydraulic Pump Motor Circuit Failure. ABS stands for Anti-lock Braking System, which is a safety feature in modern vehicles designed to prevent wheels from locking up during braking, thereby maintaining steering control and reducing stopping distances. The ABS system relies on sensors, a hydraulic pump, and motor to function effectively. When the ABS Hydraulic Pump Motor Circuit Failure code is triggered, it means that the onboard computer has detected a problem with the circuit responsible for controlling the hydraulic pump motor within the ABS system.
