C1096 Lincoln Code - ABS Hydraulic Pump Motor Circuit Open

Quick Answer

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. Common causes include Low Brake Fluid, Faulty ABS Hydraulic Pump Motor, ABS Hydraulic Pump Motor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1096 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.

4. Can I drive my Lincoln with the C1096 code active?

While the vehicle may still be drivable, the ABS system will not function properly, increasing the risk of wheel lock-up during hard braking or on slippery surfaces.

5. How is the C1096 code diagnosed?

Diagnosis involves checking the ABS pump motor circuit for open or shorted wiring, testing the pump motor and relay for proper operation, and verifying the functionality of the ABS control module.

6. How do I fix the C1096 code on my Lincoln?
