Description

This multifunction stalk/control block (COM2005 by Delphi) is a direct-fit component used on a range of Citroën and Peugeot models. It centralizes the steering-column switches for lighting, fog lamps, wipers, horn, cruise control and some radio functions, improving ergonomics and consolidating wiring compared with individual switches. Suitable for professional garages and DIY mechanics familiar with steering column disassembly. Common search terms: COM2005, Delphi stalk module, multifunction switch, Citroën stalk controls, Peugeot stalk controls, part numbers 96601446XT, 6242X3.

Technical Information

• Manufacturer: Delphi
• Model: COM2005
• Product Codes: 96601446XT, 96640423XT, 96660124XT, 98069813XT
• Additional Numbers: 6242X3, 6242GF, 6242VW

Fitment / Compatible Models

Typical compatibility includes (but is not necessarily limited to): Citroën Berlingo II, Citroën Berlingo III, Citroën C2, Citroën C3 (I and II), DS3, Peugeot Partner II, Peugeot Partner III, and related vehicles using the COM2005 platform. Always verify the part number against the vehicle’s original part marking before installation.

Installation

• Disconnect the negative battery terminal before any work to avoid short circuits and airbag deployment.
• Remove steering wheel trim and, if required, the airbag module following the vehicle manufacturer’s safety procedures.
• Unscrew/remove steering column covers to access the COM2005 module and its connectors.
• Unplug electrical connectors and release any retaining clips. If the radio/steering controls are separate, transfer the required control stalk or switch to the new unit as noted in the original description.
• Fit the replacement unit, reconnect all plugs and reassemble covers and steering wheel trim. Reconnect the battery and verify all functions: lights, fog lights, wipers, horn, cruise control and radio controls.
• If any function is inactive or intermittent after installation, check connector seating, wiring continuity and fuses before considering replacement.

Why The Part Most Commonly Fails

• Mechanical Wear: Frequent use of stalks causes switches and plastic components to wear or break over time.
• Electrical Contact Degradation: Oxidation or pitting of contacts can lead to intermittent operation of lights, wipers or horn.
• Water Ingress And Corrosion: Moisture reaching connectors or the module accelerates failures.
• Connector Or Harness Damage: Faulty wiring or damaged plugs from previous repairs or accidents causes loss of function.
• Internal Electronic Faults: Component failure on the COM2005 board (e.g., failed relays or semiconductors) can disable multiple functions.

Recommendations For Installation

• Perform installation in a dry, well-lit workshop with appropriate tools. Avoid forcing plastic clips to prevent breakage.
• Always follow the vehicle manufacturer’s disassembly sequence for steering column and airbag components.
• Inspect mating connectors and wiring harness for corrosion or damage and repair as needed before fitting the unit.
• After installation, test all affected systems (lights, wipers, horn, cruise control, steering wheel/radio switches) on the road in a safe environment.
• If functions related to vehicle electronics remain inactive, diagnostic equipment capable of reading Citroën/Peugeot fault codes (e.g. DiagBox/Lexia) can help locate interaction issues in body modules or buses.

Key Features

The COM2005 Delphi multifunction switch block manages multiple body functions from behind the steering wheel. It centralises control of lighting circuits, fog lamps, radio command, cruise control inputs, windshield wipers (front and rear) and the horn. Designed for easy integration in PSA group vehicles, it improves harness simplicity by grouping several switch functions into one module.

Compatibility

Commonly fitted to various Citroën and Peugeot models from the PSA/Stellantis range. Typical applications include:

• Citroën C2
• Citroën C3 (I and II)
• Citroën DS3
• Citroën Berlingo B9
• Peugeot Partner Tepee / Partner II

Installation And Replacement

Replacement of the COM2005 switch block is a medium-difficulty job suitable for experienced DIYers and professional mechanics. Typical steps:

1. Disconnect the negative terminal of the battery before any work.
2. Remove the steering column covers to access the multifunction switch block.
3. If required, transfer the radio/cruise stalk or associated control switches from the old unit to the replacement unit.
4. Unplug all connectors carefully, noting locking tabs and harness routing to avoid damage.
5. Fit the new unit, reconnect connectors and secure mounting screws to the correct torque.
6. Perform necessary coding or commissioning (see Coding section below).

Installation and Coding – Important

• The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
• Options for commissioning:

1. Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
2. Virginization and subsequent initialization/telecoding via DiagBox (or online) + key adaptation.

• Recommended to be carried out by a technician with PSA service equipment (DiagBox/Lexia/PP2000).
• Before removal/installation always disconnect the battery and follow the manufacturer’s procedure to avoid damaging the unit.

Common Failure Causes

Failures typically result from electrical faults or environmental damage rather than mechanical wear of the plastic housing. The most common causes are:

• Corroded or damaged connector pins from moisture ingress.
• Water penetration due to door seals or windscreen leaks affecting the switch block.
• Short circuits or voltage spikes in the vehicle electrical system.
• Faulty internal solder joints or degraded components after long service life.
• Wear of mechanical contacts in stalk switches leading to intermittent operation.

How Often It Fails

There is no fixed service interval. Lifespan depends on vehicle usage, environment and exposure to moisture or electrical problems. In practice, failures are more likely on high-mileage vehicles or those exposed to leaks, humid garages or improper jump-starting procedures.

Recommendations For Mounting

• Always disconnect the battery before starting work and wait several minutes for systems to power down.
• Inspect and, if necessary, clean the wiring harness connectors before reinstallation. Replace any corroded connectors.
• If moving the stalk/switch from the original unit, ensure correct orientation and secure mounting to avoid play.
• After installation, verify all functions (lights, wipers, horn, cruise control, radio controls) and perform any required coding or cloning with appropriate diagnostic tools.

Who Should Use This Part

Suitable for professional automechanics and experienced DIY enthusiasts performing repairs on Citroën and Peugeot vehicles. Often searched by part number during parts lookup—keeping the OEM codes handy speeds identification and procurement.
