Code C1095 Description

The C1095 code indicates an ABS Hydraulic Pump Motor Circuit Failure. The ABS (Anti-lock Braking System) is a crucial safety feature in modern vehicles that prevents the wheels from locking up during heavy braking, helping the driver maintain control and reduce stopping distances. The hydraulic pump motor is a key component of the ABS system, responsible for applying and releasing brake pressure to individual wheels as needed.
