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

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

As the central unit, the airbag control unit AW93-14D374-AD manages the SRS of Jaguar. In an accident it evaluates the sensors and decides within milliseconds which airbags and seatbelt pretensioners are activated.

During normal driving it continuously checks its connections and sensors. It shows detected faults via the airbag warning light in the instrument cluster.

After an accident it secures the crash data and locks itself. Only the repair lifts this lock.

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

A main cause is stored crash data after an accident, even if no airbag was triggered. A conventional diagnostic tool cannot empty this memory on the AW93-14D374-AD.

Airbag24 clears the memory as part of the repair. Several other causes are also possible:

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

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

On the AW93-14D374-AD, a defect can show up as the airbag warning light in the instrument cluster, which stays on permanently or only intermittently. An error message in the instrument cluster may appear alongside it.

• Airbag warning light on permanently or flickering
• Error message in the instrument cluster
• Diagnostic tool cannot find the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may fail to trigger. For this reason such a finding should be examined promptly.
