Description
Control module, pump, unit, ABS ESP ATE Citroën C5 with a piece of wiring.
This ABS/ESP pump and control module from ATE is a direct-fit unit commonly used on Citroën C5 second generation vehicles. It combines the electronic control unit and hydraulic pump in one assembly and is supplied with a short section of wiring harness to simplify replacement. The part is often sought by workshop technicians and DIY mechanics under the OE and cross-reference numbers listed below, so having these references at hand speeds up ordering and diagnosis.
The unit controls anti-lock braking (ABS), electronic stability program (ESP) and related traction-control functions by modulating hydraulic pressure at the wheels. It contains the electric motor-driven pump, solenoid valves, hydraulic block and electronic control module. When replacing this assembly it is important to perform a proper hydraulic bleed and ECU initialization to restore full system functionality.

Compatibility And Application Notes
Designed primarily for Citroën C5 II platforms. The same module is frequently listed under several OE and supplier numbers—use the product codes above when searching to find the correct match for your vehicle. The supplied short wiring harness may reduce the need for splicing during installation, but verify connector shapes and pinouts before final assembly.
How The Part Functions
The ABS/ESP module monitors wheel speed sensors and vehicle dynamics inputs to prevent wheel lock-up and help maintain directional stability. During braking events the unit modulates hydraulic pressure via internal valves and the electric pump, allowing safe braking control and supporting systems such as traction control and ESP interventions.
Replacement Procedure (Overview)
- Park Vehicle Safely And Isolate Power: Secure the vehicle on level ground, apply the parking brake and disconnect the negative battery terminal to prevent electrical damage.
- Access The Unit: Locate the ABS/ESP unit (usually in the engine bay). Remove any protective covers and the necessary components to reach the module.
- Disconnect Electrical And Hydraulic Connections: Label and unplug the electrical connectors. Cap brake lines immediately after loosening to avoid contamination.
- Remove Mounting Bolts And Extract Unit: Unbolt the assembly from its bracketry, taking care not to damage attached wiring.
- Install Replacement Unit: Fit the new unit with the supplied wiring piece, reconnect hydraulic lines and electrical connectors. Replace any cracked seals or gaskets.
- Bleed And Calibrate: Perform a complete brake bleed using a diagnostic tool to run the ABS pump cycle and evacuate air from the system. Clear fault codes and follow manufacturer procedures for unit initialization (use workshop manual or manufacturer diagnostic software where applicable).
- Functional Check: Confirm ABS/ESP lamp extinguishes and perform a road test in a safe area, monitoring brake response and stability interventions.
Installation Recommendations
- Always Disconnect The Battery Before Work To Prevent ECU Damage.
- Use Appropriate Diagnostic Equipment (e.g., Dealer Or Professional Scan Tools) To Run ABS Bleed Cycles And Clear Fault Codes After Replacement.
- Use Clean Brake Fluid And Replace Any Contaminated Lines Or Seals During Installation.
- Follow Manufacturer Torque Specifications For Fasteners And Refit All Protective Covers To Prevent Moisture Ingress.
- If The Supplied Wiring Section Differs From The Original, Verify Pinout And Secure Connections With Correct Clips Or Heat-Shrink Sleeving.
Why This Part Fails Most Often
Failures Typically Result From Long-Term Wear, Electrical Faults Or Environmental Damage. The Most Common Causes Include:
- Corrosion And Water Ingress Into The Electronic Module Or Connectors Leading To Intermittent Or Permanent Electrical Faults.
- Pump Motor Wear Or Mechanical Degradation After Prolonged Use, Especially If Brake Fluid Has Been Contaminated.
- Internal Valve Blockage Or Valve Malfunction Due To Debris Or Hydraulic Contamination.
- Connector Damage Or Broken Wiring Causing Loss Of Communication Between The ABS ECU And Vehicle Network.
Why Buy This Unit
For technicians and DIY mechanics, purchasing a unit with clear OE and supplier numbers simplifies sourcing and ensures you get a part that matches the vehicle wiring and mounting. The included wiring piece reduces modification work in many installations. Having the correct references on hand (listed above) speeds up ordering and reduces downtime in the workshop.
