Airbag control unit with part number G1ET-14B321-HC

What does the airbag control unit G1ET-14B321-HC do?

The airbag control unit G1ET-14B321-HC coordinates the restraint system in Ford. It evaluates the signals from the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and continuously checks whether the system is ready for operation.

The unit indicates faults via the airbag warning light in the instrument cluster. For you, the light is the direct feedback that something is wrong in the restraint system.

After an accident, the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit G1ET-14B321-HC fail?

Stored crash data is the most common cause of a failure of the G1ET-14B321-HC, even if no airbag has triggered; they cannot be erased with a normal diagnostic tool. Other possible causes include aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as those from a weak battery or a jump start.

Crash data can therefore be present even though the restraint system remained silent after the accident. That is why it is the first point of every fault search.

The other causes affect the electronics in different ways: through ageing, through moisture at the contacts, or through voltage spikes in the vehicle electrical system.

Airbag24 erases the data as part of the repair.

How can you tell that the G1ET-14B321-HC is defective?

The airbag warning light in the instrument cluster lights up on the G1ET-14B321-HC permanently or intermittently. A fault message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

The warning light is the visible warning the vehicle gives you. If it comes on while driving, have the system checked promptly.

Which component is affected is only shown by reading out the fault memory. A guess based on the light alone is not enough for this.

Compare the part number on the label of your unit with this page, so that you remove the right unit. Also have the fault memory read out before removal; only this result shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285011993, BM5T-14B321-CE, CM5T-14B321-CA, DM5T 14B321 SA, F1ET-14B321-CB.

How does the repair of the G1ET-14B321-HC work?

The first step is reading out the fault memory; the log goes with the unit. Before removal, disconnect the battery. Finally, create a repair order online and send the control unit G1ET-14B321-HC packed.

Airbag24 first inspects the unit on the test bench, repairs defective components and runs a function test. The crash data is erased as well. Processing usually takes 3–4 working days.

Afterwards, your own unit is returned to you. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit G1ET-14B321-HC get to Airbag24?

You send the control unit G1ET-14B321-HC to Airbag24 as a parcel or book a UPS collection for an extra charge. The return of your own unit after the repair is also made by UPS.

Enclose the printed repair order with the parcel and pack the unit shock-proof.
