Description
Overview
This ATE ABS pump and control module is designed for PSA vehicles including Citroën C2, Citroën C3 and Peugeot 207. Supplied with a piece of wiring, the unit houses the hydraulic pump and electronic control elements that manage the anti-lock braking system to maintain traction and braking stability under heavy or emergency braking.
Key Benefits
- Direct fit for specified PSA models when matching part numbers.
- Includes wiring piece to aid installation and connector compatibility.
- Restores ABS functionality: reduces wheel lockup, improves vehicle control.
- Valuable for professional mechanics and experienced DIYers searching by product code.
Typical Symptoms Of A Faulty Unit
- ABS warning lamp illuminated on the dashboard.
- Pulsating or soft brake pedal feel during normal or emergency braking.
- Loss of ABS intervention or inconsistent ABS activity.
- Intermittent faults or communication errors reported by a diagnostic tool.
Common Causes Of Failure
- Electrical faults: connector corrosion, damaged wiring or internal control module faults.
- Hydraulic issues: contaminated or degraded brake fluid can damage valves and pump motor.
- Age and wear: motors and solenoid valves can wear out after many years or high mileage.
- Moisture ingress or corrosion in brake system components.
Replacement And Installation Notes
Replacing the ABS pump requires mechanical experience. Typical steps include:
- Safely raise and support the vehicle and disconnect the negative battery terminal to avoid short circuits.
- Depressurize the brake system and drain brake fluid as needed to prevent spills.
- Disconnect electrical connectors and the supplied wiring piece, and remove hydraulic brake lines (prepare to capture fluid).
- Unbolt the ABS assembly from its mounting and transfer any brackets or sensors as required.
- Fit the new unit, reconnect hydraulic lines and electrical connectors, then refill and fully bleed the brake system to remove all air.
- After physical installation, a full diagnostic check is recommended; the replacement may require initialization or coding with a PSA diagnostic tool (for example DiagBox/Lexia) to ensure proper communication with the vehicle ECU and correct ABS operation.
Maintenance Recommendations
- Use fresh, manufacturer-recommended DOT brake fluid and replace fluid at recommended intervals to reduce contamination risk.
- Inspect connectors and wiring for corrosion periodically, especially in older vehicles or those exposed to road salt.
- Address brake system issues early to avoid secondary damage to the pump and valves.
