C1097 Lincoln Description

The Anti-Lock Brake System (ABS) prevents wheel lock-up by monitoring the wheel speed sensors and actuating Hydraulic Control Unit (HCU) modulating the brake pressure to prevent wheel lockup. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system is controlled by the Powertrain Control Module (PCM) and utilizes the ABS module for wheel speed information only. Engine Only Traction Control (EOTC) helps maintain vehicle control during acceleration by modulating engine torque when driving on slippery or loose surfaces.

The ABS Module monitors the ABS Hydraulic Pump Motor. The ABS Module sets the OBDII code when the ABS Hydraulic Pump Motor is not to factory specifications.
