Code C1097 Description

The C1097 diagnostic trouble code (DTC) indicates that there is a short to ground in the ABS hydraulic pump motor circuit. The Anti-lock Braking System (ABS) in a vehicle is responsible for preventing the wheels from locking up during braking, thus helping the driver maintain control of the vehicle. The hydraulic pump motor is a crucial component of the ABS system, as it generates the hydraulic pressure needed to operate the ABS.
