Ford Galaxy Mk3 Airbag Control Unit Repair

What is a Ford Galaxy Mk3 airbag control unit?

The Ford Galaxy Mk3 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle to provide optimal occupant protection.

This electronic module is responsible for controlling the frontal and side airbags, as well as the seat belt pretensioners. It detects and evaluates signals from peripheral crash sensors to ensure rapid response in an emergency.

The control unit contains vehicle-specific software and several ignition circuits. It also stores relevant crash and error data for later diagnosis and accident analysis.

Why is the Ford Galaxy Mk3 airbag control unit faulty?

A Ford Galaxy Mk3 airbag control unit can be defective if crash data is stored after an impact, triggering an error message and blocking the system. Internal hardware or software errors, contact problems, or aging electronics also often lead to module failure.

The most common causes are crash information stored after an accident that prevents the error log from being erased. This requires a special Ford Galaxy Mk3 airbag control unit repair.

Other causes can include internal defects in the control unit electronics or communication errors with other vehicle systems. These problems often manifest themselves as an illuminated airbag warning light on the dashboard and require precise diagnosis.

Common error codes for Ford Galaxy Mk3 airbag control unit repair

A Ford Galaxy Mk3 airbag control unit repair is often necessary due to specific error codes that indicate problems directly within the control unit. These codes indicate internal circuit faults, communication problems, or problems with the airbag deployment circuits, requiring a precise diagnosis.

• B0001 → Driver side airbag circuit error → High resistance or open circuit
• B0002 → Second stage driver side airbag circuit error → Problem with the second airbag stage ignition circuit
• B1000 → Control unit communication error → Internal fault in control unit communication
• B2293 → Second stage driver side airbag circuit low resistance → Low resistance in the second airbag stage firing circuit

What part numbers are available for the Ford Galaxy Mk3 airbag control unit repair?

For Ford Galaxy Mk3 airbag control unit repairs, several OEM part numbers are relevant to ensure compatibility. These include Siemens, Bosch, and Ford-specific part numbers, making it easier to select the correct replacement part or identify the module to be repaired.

• 1J0 909 603 → Siemens / Bosch → Original airbag control unit
• 5WK4163 → Siemens → OEM part number for control unit
