Lexia-3 Module S.1279 OBD2 Adapter Cable for Peugeot Boxer & Citroen

Lexia-3 Module S.1279 OBD2 Adapter Cable for PSA Diagnostic Vehicles

• ✔ Robust workshop quality for daily diagnostic use
• ✔ Stable signal transmission for reliable ECU communication
• ✔ Precisely fitting OBD2 connectors for secure vehicle connection
• ✔ High-quality contacts for consistent diagnostic connections
• ✔ Developed for professional Lexia-3 and PPS2000 diagnostic environments

The Lexia-3 Module S.1279 Adapter Cable was specially developed for selected Citroen and Peugeot vehicles where adapted diagnostic communication is required. The module connects the existing Lexia-3 diagnostic interface with compatible PSA vehicles and ensures stable data transmission between the vehicle and the diagnostic interface.

This item is an adapter or connection cable and not a diagnostic device or scanner. The module is used exclusively for the correct adaptation of the diagnostic lines between the vehicle and existing diagnostic hardware.

Compatible with selected PSA vehicle platforms

The diagnostic module is suitable, among others, for vehicles with differing diagnostic architecture within the PSA group. Adapted communication lines are particularly needed for commercial vehicles and vans.

• Peugeot Boxer III
• Peugeot Bipper
• Citroen Jumper III
• Citroen Nemo

Compatibility is model-dependent and ECU-dependent. The module was developed for use with Lexia-3 PPS2000 diagnostic interfaces.

Why the S.1279 module is needed

Some PSA vehicles have different pin assignments within the OBD2 connector. Without proper adaptation, individual control units may not be recognized, or the diagnostic connection may operate unstably.

The OBD2 adapter cable handles the correct signal routing between the vehicle and the diagnostic interface. This enables stable communication with the control units.

Important advantages of high-quality diagnostic adapters

For professional diagnostic work, the quality of the connections plays a decisive role. Inferior adapters can lead to connection interruptions, faulty data packets, or unstable ECU communication.

• Clean signal transmission without communication disturbances
• Robust plug contacts for frequent workshop use
• Reliable connection between vehicle and diagnostic interface
• Stable data communication in CAN-Bus and K-Line systems
• Reduction of contact problems through high-quality manufacturing

Shielded signal routing for reliable diagnostic work

Modern vehicles work with sensitive data lines and various bus systems. High-quality shielding helps to minimize electrical interference during diagnostic communication.

Especially in a workshop environment with numerous electrical consumers, stable signal routing ensures a reliable connection between the vehicle and the diagnostic system.

Use in professional workshop everyday life

The S.1279 module is frequently used for diagnostic work on vans and commercial vehicles. Workshops benefit from stable communication during maintenance, service, and fault diagnoses.

• Reading out error codes
• ECU communication in PSA commercial vehicles
• Support for diagnostic work with Lexia-3
• Connection between vehicle and PPS2000 interface
• Workshop use for Citroen and Peugeot vehicles

Technical properties of the adapter module

• Type: Module S.1279 Diagnostic Adapter
• Connection: OBD2 plug to OBD2 socket
• Compatibility: Lexia-3 / PPS2000 diagnostic interfaces
• Application area: Citroen and Peugeot vehicles
• Usage: Connection cable for adapting diagnostic communication

The module itself does not perform any diagnostic functions. The diagnostic functions are provided exclusively by the diagnostic device used or the diagnostic software employed.

Robust processing for long-term use

The sturdy design of the adapter cable was developed for regular workshop use. High-quality connectors and resistant materials ensure durable use even with frequent plugging and unplugging.

Thanks to the precise manufacturing, the connection between the vehicle and the diagnostic interface remains reliably stable even with intensive use.
