Description
Overview
This ESP, Central Locking & PDC Switch (Part No. 96631922ZD) for the Citroën C3 Picasso is a cost‑effective used replacement designed to restore stability control, parking distance control and central locking functions. It is aimed at professional automechanics and experienced DIY repairers who search by part number to quickly identify compatible components.
Function And Benefits
- Controls ESP/ESC enable/disable inputs and interfaces with vehicle stability systems via the CAN network.
- Manages Parking Distance Control (PDC) commands for enabling/disabling the parking sensors.
- Acts as a user interface for central locking commands and may carry signals to the body control module.
- Part number identification (96631922ZD, 6242PX) simplifies finding a direct replacement for repairs.
- Used part option reduces repair cost while keeping original equipment compatibility.
Common Faults And Causes
- Intermittent or complete loss of central locking response due to worn contacts or broken internal switches.
- ESP or stability control warning lights and inability to engage/disengage ESP — often caused by faulty switch contacts, wiring faults or CAN communication errors.
- Parking sensors not enabling/disabling properly when controlled from the switch — caused by internal switch failure or connector corrosion.
- Damage from moisture ingress, physical wear, short circuits or connector corrosion are frequent causes of failure in dashboard switches.
Replacement And Installation Guidance
The following high‑level steps are intended for mechanically competent users and professional workshops. If you are unsure, consult a workshop manual or a qualified technician.
- Safety first: Disconnect the negative terminal of the vehicle battery and wait a few minutes before working on dashboard electrical components to avoid short circuits and unintended airbag/system triggers.
- Remove the trim panels surrounding the switch cluster carefully using appropriate trim tools to avoid damage to clips and panels.
- Unplug the electrical connectors from the back of the switch, inspect pins and connector housings for corrosion or damage, and clean if necessary.
- Install the replacement switch, reconnect connectors and reassemble trim. Reconnect the battery and perform a basic function check (central locking, ESP switch operation, PDC enable/disable).
- If the vehicle reports errors or requires adaptation, perform a diagnostic scan with an OBD tool. Some vehicles may require coding or module adaptation after switch replacement to ensure full functionality on the CAN network.
- Check related fuses and wiring if problems persist; intermittent faults may be wiring or module related rather than the switch itself.

Compatibility And Notes
This unit is a used replacement part. The reliability and functionality of this used component have been checked according to the supplier description. Always verify the part numbers and connector types against your vehicle before purchase. For full system recovery it may be necessary to perform diagnostics and coding after installation, especially if the vehicle uses body control module programming or immobilizer linking.
If you are repairing a Citroën C3 Picasso (or a compatible C5 II where applicable), this switch provides an economical route to restore ESP, parking assist and central locking functionality while keeping OEM fitment.
