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

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

The airbag control unit G1ET-14B321-AD is the control unit of the restraint system (SRS) of Ford. It processes the signals from the crash sensors and decides in the event of an accident which airbags and seatbelt pretensioners are triggered.

The unit also monitors the system during operation. It indicates detected faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself. The following sections describe the effects on the repair.

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

Stored crash data is the most common cause, even if no airbag was deployed in the accident. Other possible causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data cannot be removed with a standard diagnostic tool. The other causes affect the electronics and their connections; voltage spikes occur, for example, with a weak battery or when jump-starting the vehicle.

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

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared. In a crash, the airbags and seatbelt pretensioners may then fail to deploy.

These signs clearly indicate that the system needs to be checked.

A warning light that does not go out after starting requires an inspection. Reading out the fault memory shows the stored message.

Which vehicles is the G1ET-14B321-AD fitted in?

Comparing the part number with the label on the removed unit only shows that you have the correct unit in front of you. Before that, have the fault memory read out, because only its result clarifies whether the control unit is defective or whether a connector 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-AD work?

First have the fault memory read out and enclose the report. Then disconnect the battery, and only then remove the control unit and create a repair order online. Airbag24 checks the unit, replaces defective components, deletes stored crash data and carries out a function test; processing usually takes 3–4 working days.

The fixed sequence serves safety. Afterwards your own unit is returned after the function test.

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-AD get to Airbag24?

The unit is sent to Airbag24 as a parcel, or you can book a UPS collection for an extra charge. The return journey after the repair is handled by UPS.

Pack the control unit shock-proof and include the printed repair order.
