Description
Product Overview
This Bosch ABS control module, part number 0273004440 (also referenced as 454153 and 9636084480), is designed specifically for use in Citroën Xsara and Peugeot 306 models. It plays a critical role in managing the Anti-lock Braking System (ABS), enhancing vehicle safety by preventing wheel lock-up during sudden braking or slippery road conditions.
The module includes the hydraulic pump and electronic control unit integrated into a compact assembly, along with a piece of the wiring harness to facilitate proper electrical connectivity. This setup ensures precise modulation of the brake pressure to each wheel, resulting in improved control and braking efficiency.
Application and Installation
Suitable for Citroën Xsara and Peugeot 306 vehicles equipped with ABS systems, this module is typically replaced when the ABS warning light remains illuminated, braking performance degrades, or when diagnostic codes indicate module failure. Installation requires disconnecting the battery, removing the old ABS unit, disconnecting associated hydraulic and electrical lines, and fitting the new module with careful attention to the wiring harness connection. After installation, a professional ABS system reset and bleeding of the brake lines are necessary to ensure proper function.
ABS control modules may fail over time due to wear on internal pumps, electronic faults, or exposure to moisture and contaminants. Regular inspection of the ABS warning system and prompt replacement of faulty modules are essential to maintain safe braking performance.
