Description
ATE ABS/ESP Control Module designed for Citroën C3 Pluriel (1.6 16V Sensodrive). Searchable by primary OE: 9649028880 and alternative references 10.0206-0101.4, 10.0960-1125.3, 454190, 4541C1, 4541S0, 454294, 454295. This unit combines the electronic control module with the hydraulic pump used by the ABS and ESP systems.
Function
The ABS/ESP control unit continuously monitors wheel speed sensors and driver inputs to modulate brake pressure via the hydraulic pump and valves. During wheel slip or emergency braking the module reduces individual wheel pressure to maintain vehicle stability and shorten stopping distances. The pump and valve block restore pressure when required and provide anti-lock braking and electronic stability interventions.
Fitment And Compatibility
Primary fitment: Citroën C3 Pluriel 1.6 16V with Sensodrive transmission. The part number 9649028880 is used across several PSA small-car platforms; always verify compatibility using the OE numbers listed above before ordering.
Replacement And Installation Notes
- Park the vehicle on a level surface, isolate the battery negative terminal to prevent electrical damage.
- Locate the ABS/ESP unit (typically mounted in the engine bay close to the firewall) and protect brake lines to avoid fluid loss.
- Disconnect electrical connectors and carefully loosen brake line fittings, catching any brake fluid and preventing contamination.
- Unbolt the module from its bracket and remove. Fit the replacement unit, torque fasteners to manufacturer values and reconnect wiring harness.
- Refill and properly bleed the brake system to remove air from all circuits. Clear fault codes with a diagnostic tool and confirm proper ABS/ESP operation with a test drive.
Common Failure Modes
Typical causes of ABS/ESP unit failure include internal pump wear, relay or valve faults, electrical connector corrosion, moisture ingress and damaged wiring. Symptoms often include ABS or ESP warning lights on the dashboard, intermittent braking feel, or fault codes relating to pump motor circuits or valve control.
Condition And Supply
This specific unit is supplied with a piece of the wiring harness and is stated as tested and fully functional by the supplier. It is sold as a direct replacement for matching OE numbers; ensure cross-reference before installation.
