Description
Overview
This ABS ESP Control Module ATE is a vital electronic unit designed for the Citroën C5 I, ensuring effective anti-lock braking system (ABS) and electronic stability program (ESP) functionality. It plays a crucial role in maintaining vehicle safety by preventing wheel lock-up during braking and enhancing stability on slippery surfaces.
Function and Importance
The module controls the ABS pump and valves, modulating brake pressure to each wheel individually based on input from wheel speed sensors. This action prevents skidding and loss of control, especially during emergency braking or difficult road conditions. Besides ABS, the ESP function actively improves vehicle handling by applying targeted braking to reduce understeer or oversteer.
Compatibility and Application
This specific control unit is compatible with the first generation (C5 I) Citroën models manufactured between years 2001 and 2008. It also fits various Peugeot vehicles sharing the PSA platform. Typical part numbers include 9648606980, 10.0206-0072.4, and 10.0960-1128.3. Commonly cross-referenced with OEM codes 454192, 454193, 454297, and 454298.
Replacement and Maintenance
ABS ESP modules may fail due to electrical faults, corrosion in connectors, or internal pump motor issues, often after 150,000 km depending on driving conditions. Symptoms of failure include warning lights on the dashboard, inconsistent braking performance, or noise from the ABS pump. Replacing the module requires diagnostic tools to reset the system and sometimes manual calibration post-installation.
