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

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

The airbag control unit DW93-14D374-AF coordinates the restraint system (SRS) in the vehicle of Jaguar. It evaluates the crash sensors and decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners. After an accident it stores crash data and locks itself.

The unit constantly checks the components of the system; if it finds a fault, it indicates this via the airbag warning light. The unit is therefore the central point where the system is monitored.

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

First and foremost on the DW93-14D374-AF is crash data from an accident, even if no airbag was triggered. A normal diagnostic tool cannot remove this data; this is only done during the repair by Airbag24.

Further causes are components that age over time, cold solder joints inside the unit, and moisture and corrosion at the plug connections. Voltage spikes, for example from a weak battery or a jump start, can also stress the control unit.

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

The airbag warning light in the instrument cluster reports a defect on the DW93-14D374-AF by lighting up permanently or intermittently. A fault message in the instrument cluster or a disturbed connection to the diagnostic tool also points to this.

Typical indications at a glance:

• Permanent or intermittent lighting of the airbag warning light
• Fault message in the instrument cluster
• No connection can be established to the diagnostic tool
• Fault memory that cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. A check is therefore advisable as soon as the light comes on.
