Description
Overview
Used TRW ABS/ESP control module with integrated hydraulic pump and a section of wiring harness, designed for Peugeot 407 models. This module is responsible for managing the Anti-lock Braking System (ABS) and the Electronic Stability Program (ESP), improving vehicle safety by preventing wheel lock-up during heavy braking and helping to maintain stability under loss-of-traction conditions.
What This Part Does
The ABS function modulates brake pressure to prevent wheel lock, preserving steering control during emergency braking. The ESP function works with wheel-speed sensors and the ABS hydraulic unit to apply selective braking and engine torque adjustments to stabilize the vehicle in critical maneuvers. The hydraulic pump and internal valves allow controlled pressure changes across brake circuits.
Installation & Practical Notes
- Compatibility: Primarily for Peugeot 407 models. Verify the listed product codes against your vehicle before purchase.
- Preparation: Disconnect the vehicle battery before starting work to avoid electrical damage or fault codes.
- Replacement Steps (general guidance): Disconnect battery, remove electrical connectors and any protective covers, unbolt the ABS/ESP unit, transfer or connect the wiring harness, mount the replacement unit, then reconnect electrical connectors and battery.
- After Installation: It is normally necessary to bleed the brake system and clear or read fault codes with a diagnostic tool. Many vehicles require module coding/pairing to the vehicle and verification with a compatible diagnostic scanner to ensure full functionality.
- Recommended For: Professional fitment by a qualified technician or experienced DIYers with the correct tools and diagnostic equipment.
Common Failure Causes
Failures can occur due to electrical faults (corroded connectors, damaged wiring), moisture ingress, wear of internal hydraulic components or pump motor failure, and long-term exposure to road salts. Addressing underlying electrical or corrosion issues helps prevent repeat failures.
Benefits Of Choosing This Part
Offering a cost-effective replacement option, this TRW ABS/ESP module provides core braking and stability functions for compatible Peugeot 407 vehicles and includes a portion of the wiring harness to simplify installation. Ideal for workshops and knowledgeable DIYers who need a direct-fit solution and verified part numbers.
