Code C1098 Ford Description

The C1098 Ford code indicates a problem with the ABS hydraulic pump motor circuit, specifically a short to the battery. The ABS (Anti-lock Braking System) is a safety feature in vehicles that prevents the wheels from locking up during braking, helping the driver maintain control and avoid accidents. The hydraulic pump motor is a crucial component of the ABS system, responsible for building up hydraulic pressure to control the brakes.
