Airbag control unit with part number GX73-14D374-AG

What does the airbag control unit GX73-14D374-AG do?

As the airbag control unit GX73-14D374-AG, the unit controls the restraint system (SRS) at Jaguar. In an accident it checks the signals from the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds. At the same time it monitors the system and reports faults via the airbag warning light; after an accident it stores crash data and locks itself.

The sensors, seatbelt pretensioners and the lines between them are included in this monitoring. Every detected fault is stored in the fault memory.

Why does the control unit GX73-14D374-AG fail?

The most common cause is crash data from an accident, even if no airbag has fired; a normal diagnostic tool cannot erase it. Also possible are aging electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes.

The crash data remain stored in the unit. Airbag24 erases them during the repair, so you do not have to take care of that yourself.

Aging electronic components and cold solder joints can lead to contact problems that the control unit detects as a fault.

Moisture and corrosion act on the plug connections; voltage spikes, for example from a weak battery or a jump-start, additionally stress the electronics.

How can you tell that the GX73-14D374-AG is defective?

If the airbag warning light in the instrument cluster stands out because it stays on permanently or only intermittently, that is a warning sign. In addition there may be a fault message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be erased. Then airbags and seatbelt pretensioners may not be able to trigger in an emergency.

The warning light is the most important hint your vehicle gives you. Have it checked promptly.
