Description
Product Overview
Replacement ESP switch and central locking control for Citroën C5 II. This module is commonly referenced by part numbers 96498318YW and 6554JG and fits PSA Group vehicles from the Citroën/Peugeot family where this part is specified. It combines the Electronic Stability Program (ESP) on/off control with central locking operation in the vehicle’s switch cluster.
Function And Benefits
The ESP switch allows the driver to enable or disable the Electronic Stability Program and traction-assist interventions. The integrated central locking control operates door locking/unlocking and can be part of the vehicle’s convenience switch assembly. Replacing a worn or faulty unit restores correct ESP operation and reliable door locking response, improving safety and everyday usability.
Common Symptoms And Failure Causes
Typical symptoms indicating a faulty switch include an illuminated ESP warning light, inability to toggle ESP functions, irregular central locking behaviour or unresponsive switch buttons. Causes of failure are usually mechanical wear from frequent use, ingress of moisture or dirt, corrosion of electrical contacts, impact damage to the switch bezel, or wiring/connectivity faults in the harness.
Replacement Notes And Workshop Tips
Before starting any electrical work, disconnect the negative battery terminal to avoid short circuits or unintended airbag/ECU warnings. Remove surrounding trim panels using plastic trim tools to avoid damage, then access the switch by unscrewing the retaining screws or releasing the snap clips depending on the vehicle trim. Disconnect the electrical connector, replace the switch, reconnect, and reassemble. Basic hand tools and trim removal tools are typically sufficient. In many cases no ECU programming is required after replacement, but always verify with your vehicle’s service manual and clear any stored fault codes after installation.
Fitment Advice
This part is intended for Citroën C5 II models. Always confirm compatibility by checking the vehicle identification number (VIN) and the OEM part number before ordering. The component is frequently searched by its product codes, so matching 96498318YW or 6554JG to your vehicle’s parts list is recommended.
