Airbag control unit with part number 5WK44001

What is the function of the airbag control unit 5WK44001?

The airbag control unit with part number 5WK44001 is an original Bosch module that serves as the central control unit for the occupant protection system in the SsangYong Chairman CW700. It processes data from the acceleration sensors to precisely and rapidly deploy the airbags and seatbelt pretensioners in the event of a collision, while also recording system data.

Technically speaking, this control unit is the brain of the passive safety system. It maintains constant communication with the satellite sensors located at the front and sides of the vehicle to assess the severity and nature of an impact.

Based on this analysis, the module determines which restraint systems need to be activated. Following a crash, relevant data—known as crash data—is permanently stored in the device’s internal memory.

Why does the control unit 5WK44001 fail?

Failures of the 5WK44001 are usually due to hardware-related causes. Common failure modes include electronic malfunctions on the circuit board, water damage leading to corrosion and short circuits, or the storage of crash data after an accident, which effectively locks the control unit and makes repair unavoidable.

Water damage is particularly critical, as moisture attacks the sensitive electronic components and conductive traces on the circuit board. This can result in sporadic malfunctions or complete failure of the unit.

Internal electronic defects may affect memory chips or other components and often manifest as specific fault codes that can be read during diagnostics.

After an airbag deployment, the control unit is locked by the manufacturer. This lock caused by stored crash data is not a defect in the traditional sense, but it renders the unit unusable until it is professionally reset and inspected.

How do you recognize a defect in the 5WK44001?

A defect in the 5WK44001 control unit typically manifests unmistakably through the red airbag warning light (SRS warning light) in the instrument cluster, which remains steadily illuminated or flashing. This warning indicates that the entire restraint system may be deactivated and would fail to deploy in the event of a crash, posing a significant safety risk.

The warning light does not extinguish after starting the engine as usual; instead, it stays on continuously. This is a clear sign of a fault stored in the system, requiring immediate professional inspection.

With the warning light illuminated, the functionality of the airbags and seatbelt pretensioners is no longer guaranteed. The vehicle thus loses occupant safety, making prompt diagnosis and repair essential.

In which vehicles is the 5WK44001 installed?

The Bosch airbag control unit with part number 5WK44001 is specifically designed for the SsangYong Chairman CW700. At Airbag24, this module is expertly refurbished for vehicles of this model series produced between 2013 and 2017, restoring full functionality to the safety system.

At Airbag24, the 5WK44001 control unit is repaired for the following model:

Is repairing the 5WK44001 worthwhile?

Yes, repairing the 5WK44001 is a highly cost-effective solution. While repairs for other control units often range from 90 to 300 euros, the restoration costs for this module are comparatively low. You save on the high expense of a new part and any potentially complex re-coding required at an authorized dealer.

A key advantage of repair is that the original, vehicle-specific control unit is retained. After refurbishment, it can usually be reinstalled without additional programming.

Additionally, you contribute to sustainability by avoiding the consumption of new resources needed to manufacture a replacement part. A 12-month warranty is provided on all repairs performed.

How is the 5WK44001 professionally repaired?

At Airbag24, the repair of the 5WK44001 follows a systematic diagnostic and restoration process. Upon receipt, the control unit undergoes a comprehensive electronic analysis to pinpoint the exact source of the fault. Defective components are then replaced, crash data is erased, and a final functional test ensures full operational readiness.

First, the device is examined using state-of-the-art diagnostic tools to read all stored fault codes and identify the root cause of the malfunction—whether it’s component failure or accumulated crash data.

In the next step, repair is performed at the component level. Faulty electronic parts or memory modules are replaced with high-quality aftermarket components.

Following successful repair, a comprehensive test report is prepared, confirming the restoration of all functions. The control unit is then readied for return shipment.

What shipping options does Airbag24 offer?

Airbag24 provides you with a straightforward and flexible shipping process. For the outbound shipment, you can either send the control unit yourself free of charge or arrange a convenient UPS pickup at your preferred location.
