Description
Overview
This TRW ABS/ESP control unit with integrated hydraulic pump is designed for Peugeot 407 vehicles from the PSA group. It regulates anti-lock braking (ABS) and electronic stability program (ESP) functions by modulating brake pressure and communicating with wheel speed and vehicle sensors to maintain control in emergency or low-traction situations. The unit is supplied with a piece of wiring.
Fitment And Compatibility
Direct fit for Peugeot 407 models (PSA). This item is commonly referenced by the OE and product codes listed below. Always verify compatibility with your vehicle VIN or the original part number before ordering.
Function And Typical Failure Signs
The ABS/ESP module controls hydraulic brake modulation to prevent wheel lock and to enable stability control interventions. Common causes of failure include electrical faults, connector corrosion, moisture ingress, and hydraulic contamination. Typical symptoms are ABS or ESP warning lights on the dashboard, intermittent braking assistance, a change in brake pedal feel, or stored fault codes detectable with a diagnostic scanner.
Replacement Notes
Replacement should be carried out by a qualified technician or an experienced DIYer. Typical replacement procedure:
- Disconnect the vehicle battery to avoid electrical damage.
- Locate and unbolt the ABS/ESP unit (commonly positioned near the brake master cylinder in the engine bay).
- Carefully disconnect electrical connectors and brake lines; cap brake lines to limit fluid loss and contamination.
- Install the replacement unit, reconnect lines and wiring, then refill and thoroughly bleed the brake system to remove all air.
- Use a diagnostic tool to read and clear fault codes and to code/pair the new ABS/ESP unit to the vehicle; steering angle sensor reset or calibration may also be required.
Note: Proper coding and calibration with appropriate diagnostic equipment is often required for the unit to function correctly after installation.
