Airbag control unit with part number AW93-14D374-BD

What does the airbag control unit AW93-14D374-BD do?

The control unit AW93-14D374-BD is the airbag control unit in the restraint system (SRS) of Jaguar. It reads the signals of the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered. It also monitors the entire system.

Faults appear via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself.

Why does the control unit AW93-14D374-BD fail?

Stored crash data from an earlier accident is the most common cause, even if no airbag has deployed. An ordinary diagnostic tool cannot erase it; Airbag24 removes it during the repair of the AW93-14D374-BD.

That this data is erased at Airbag24 matches this finding. Besides this, aged components, cold solder joints, moisture and corrosion at plug connectors, as well as voltage spikes from a weak battery or a jump start, are possible.

How can you tell that the AW93-14D374-BD is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears, and the fault memory remains. The diagnostic tool does not connect to the AW93-14D374-BD.

You can recognise the fault by these signs:

• Airbag warning light stays on permanently or intermittently
• Error message in the instrument cluster
• No connection to the diagnostic tool
• Fault memory cannot be cleared

Then airbags and seatbelt pretensioners may fail to trigger in an emergency.
