The BSM module (Engine Servitude Box) represents a multifunctional electrical control unit. It integrates printed circuits, fuses, relays, and connections for the automatic management of the main devices' power supply.

Main specifications:

• Original code: 9807028780
• Type: fuse/relay control unit
• Supported fuses: standard blade from 10 A to 40 A
• Integrated relays: management of fans, pumps, lights, wipers, ignition
• Connections: multi-connector for CAN line and engine wiring
• Structure: body in ABS, with double-layer printed circuit board and internal protections

The module is designed to withstand vibrations, thermal shocks, and humidity, with specific protection ratings for the engine compartment environment.

BSM module functionalities in PSA vehicles

The BSM 9807028780 module is responsible for controlling and protecting the main electrical circuits. It acts as a central hub for current distribution starting from the battery and communicates with the engine control unit and the body computer.

Main functions:

• Distribution of current to fans, headlights, wipers, climate compressor, and pumps
• Automatic activation and deactivation via electronically controlled relays
• Management of the fuel pump relay, fan relays, and dashboard ignition
• Communication with ECU and BSI via CAN-BUS network
• Protection against short circuits, overloads, and abnormal voltages

The proper functioning of the BSM module is essential for vehicle starting and for managing most electrical devices.

DIPA can intervene to review these modules thanks to its experience and expertise.
