Airbag control unit with part number EX53-14D374-AE

What does the airbag control unit EX53-14D374-AE do?

The airbag control unit EX53-14D374-AE controls the restraint system (SRS) of Jaguar. In an accident it evaluates the crash sensors and decides within milliseconds which airbags and seatbelt pretensioners are triggered.

During operation it checks the entire system continuously and displays faults via the airbag warning light. After an accident it stores crash data and locks itself.

Why does the control unit EX53-14D374-AE fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and corrosion at plug connectors and voltage spikes also play a role.

Which cause applies to your unit becomes clear only when the fault memory is read out.

• stored crash data from an earlier accident
• aged electronic components
• cold solder joints
• moisture or corrosion at plugs
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the EX53-14D374-AE is defective?

A defect shows up in the airbag warning light, which lights up permanently or intermittently, and in fault messages in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may then not deploy.

Typical signs are:

• a fault message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• a fault memory that cannot be cleared
• the warning light on permanently or intermittently

If you notice these signs, have the system checked promptly.
