Airbag control unit with part number DW93-14D374-AB

What does the airbag control unit DW93-14D374-AB do?

The airbag control unit DW93-14D374-AB coordinates the restraint system (SRS) for Jaguar. It reads the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

If the unit detects a fault, it shows this via the airbag warning light in the instrument cluster.

Why does the control unit DW93-14D374-AB fail?

On the DW93-14D374-AB, the most common cause is crash data stored after an accident, even without an airbag having been triggered. A normal diagnostic tool cannot erase it. Further causes are listed below.

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Airbag24 removes the crash data as part of the repair.

How can you tell that the DW93-14D374-AB is defective?

On the DW93-14D374-AB, you can recognise a defect by an airbag warning light that stays on permanently or intermittently, an error message in the instrument cluster, a lack of connection to the diagnostic tool, and a fault memory that cannot be cleared.

The airbag warning light in the instrument cluster is the clearest sign. In an emergency, airbags and seatbelt pretensioners may not deploy. Therefore have the warning checked promptly.
