This ABS/ESP control module from TRW is a combined hydraulic pump and electronic control unit designed for PSA Group vehicles, primarily matching Peugeot 407 applications. The unit includes the ABS/ESP block and is supplied with a piece of the original wiring harness. Customers frequently search by part numbers such as 15710601, 9658028480, 4541X4 and 4541X3, so this listing is optimized for those references.

Key Functions

• Controls ABS (anti-lock braking) and ESP (electronic stability program) functions by modulating brake pressure via solenoid valves and an integrated hydraulic pump.
• Monitors wheel speed sensors and vehicle dynamics sensors to prevent wheel lock-up and assist vehicle stability control interventions.
• Contains electronic diagnostics and fault reporting to the vehicle’s dashboard (ABS/ESP warning lamps).

Compatibility

Designed for Peugeot 407 and compatible PSA Group models that use the listed part numbers. Always verify fitment by matching your vehicle’s OEM reference numbers: 15710601, 9658028480, 4541X4, 4541X3.

Replacement And Installation Notes

• Location: Typically mounted in the engine bay/brake system area and attached to hydraulic brake lines and electrical connectors.
• Removal: Disconnect battery before work. Carefully disconnect hydraulic lines to avoid contamination and recover brake fluid appropriately. Remove mounting bolts and electrical connectors.
• Installation: Install unit, reconnect hydraulic lines and electrical connectors. Refill and bleed the brake system thoroughly to remove air from the circuit.
• Additional Steps: Depending on vehicle build, the replacement unit may require electronic coding or adaptation to the vehicle’s ECU. We recommend checking vehicle-specific service information or using diagnostic equipment after installation.

Common Failure Modes

Failures are usually caused by electrical faults, corrosion and moisture ingress, internal pump motor or valve wear, or damage from collisions. Symptoms include illuminated ABS/ESP warning lights, degraded braking feel, pulsation during braking, or loss of ABS/ESP functions. There is no fixed service interval; failures are typically age- or environment-related.

Why Choose This Unit
