Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C4 Picasso (up to 2013), DS4, Peugeot 3008 I, Peugeot 5008 I
• Product Codes: 9666405677, 470706, 470703
• Other Numbers: 470706 (reference), 470703 (alternate reference)

Fitment And Function

The switch mounts in the center console and sends electrical pulses to the EPB control system to engage or release the parking brake. In normal operation the driver presses or releases the switch to command the EPB motor/actuator. Symptoms indicating a faulty switch include inability to engage/disengage the parking brake, illuminated EPB warning light, or intermittent operation requiring multiple presses.

Installation Recommendations

• Always disconnect the vehicle battery before starting work to avoid short circuits or damage to vehicle electronics.
• Remove the center console trim panels carefully to access the switch. Use trim tools to avoid damaging clips and surrounding plastic.
• Unplug the electrical connector and remove the retaining screws or clips holding the switch in place. Replace with the new unit and ensure the connector is fully seated and locked.
• Reassemble trim and reconnect the battery. Perform a function test: operate the parking brake several times and verify indicator behavior on the instrument cluster.
• If The Vehicle Displays EPB Faults After Replacement: Some vehicles require an EPB initialization or calibration using a diagnostic tool compatible with PSA/Stellantis systems (for example DiagBox). If initialization is required, perform it with proper diagnostic equipment or have it completed by a qualified workshop.
• Follow manufacturer service procedures and torque specifications where applicable to avoid damage during reassembly.

Why This Part Most Commonly Fails

Failure of the EPB switch is usually caused by mechanical wear of the switch mechanism, degraded internal contacts, or contamination from spilled liquids and dirt getting into the console. Repeated heavy use, brittle plastics from age, and connector corrosion can also lead to intermittent or permanent loss of function. In some cases, what appears to be a switch fault is actually an issue with wiring, connectors or the EPB actuator/control unit, so inspect related components during replacement.

This used unit has visible signs of prior use but is fully functional. If you rely on accurate part matching, use the product codes listed above when searching or ordering to ensure correct fitment.

Function

The switch operates as the driver interface for the Electronic Parking Brake (EPB) system. When activated, it sends the command to the vehicle control module to engage or release the electric parking brake actuators at the rear wheels. A correctly working switch ensures safe parking, hill-hold performance and prevents parking brake warning faults.

Replacement Procedure

1. Park the vehicle on a flat surface and apply appropriate safety measures.
2. Disconnect the negative battery terminal before starting work.
3. Remove center console trim or surrounding bezel to access the EPB switch (trim tools recommended to avoid damage).
4. Unplug the electrical connector from the old switch and remove any retaining screws or clips.
5. Fit the new switch, secure fastenings and reconnect the electrical connector.
6. Reinstall trim pieces, reconnect the battery and perform a system check.
7. After installation, carry out EPB initialization or system check using a diagnostic tool or follow the vehicle service manual procedure to ensure proper calibration.

Why The Part Most Commonly Fails

• Electrical Contact Wear Or Oxidation: Frequent use and moisture ingress can degrade switch contacts, causing intermittent function or failure.
• Mechanical Wear: Repeated actuation and harsh handling of trim can damage the switch mechanism or mounting points.
• Connector Or Wiring Issues: Corroded pins or damaged wiring can interrupt the signal to the EPB control module, producing warning lights or fault codes.
• Symptoms Of Failure: Illuminated parking brake or ABS/ESP warning lights, Inability To Engage/Release The Parking Brake, Intermittent Operation.

• Other Numbers: No additional OEM cross-references provided

Compatibility

Fits Citroën C4 Picasso (first generation, including pre- and post-facelift variants produced until 2013). Verify part numbers against the vehicle’s existing switch or parts list when possible. Commonly searched by reference numbers 96597938ZD or 470703.

Function

The EPB switch is the driver-operated control that activates and releases the vehicle’s electronic parking brake. When operated, it sends a signal to the EPB control module (and sometimes to ABS/ESP systems) to apply or release the parking brake actuators. A properly working switch ensures predictable engagement, clear dashboard indication, and safe parking/braking behaviour.

Common Failure Reasons

Failures typically stem from electrical contact wear, connector corrosion, moisture ingress, or internal mechanical/electrical deterioration of the switch assembly. Symptoms include intermittent operation, illuminated EPB or brake warning lights, inability to apply or release the parking brake, or the switch feeling loose or unresponsive. Wiring faults or issues in the EPB control module can produce similar symptoms, so confirm diagnosis before replacing the switch.

Installation Recommendation

Basic replacement steps (for experienced technicians or competent DIY mechanics):

• Disconnect the vehicle battery before starting work to avoid short circuits and prevent damage to vehicle electronics.
• Remove surrounding trim panels on the centre console to access the switch (use appropriate trim tools to avoid damage).
• Unplug the electrical connector and remove any retaining screws or clips holding the switch in place.
• Install the new switch, reconnect the connector, refit trim, and reconnect the battery.
• After replacement, check EPB operation: apply and release the parking brake several times and confirm no warning lights remain.

Note: In some cases the EPB system may require initialization or a system reset with a diagnostic tool to restore full functionality. If a diagnostic or calibration procedure is needed, use appropriate PSA-compatible diagnostic equipment or consult a specialist.

Why This Part Often Fails

The switch is frequently exposed to repeated mechanical use and to the local environment inside the console where spilled liquids, dust or humidity can penetrate connectors. Over time, internal contacts wear, plastic parts can crack, and corrosion can develop on terminals. Repeated cycling of the EPB (city driving with frequent stop-and-go) and poor electrical connections accelerate wear and eventual failure.
