Airbag control unit with part number H2GT-14B321-AA

What does the airbag control unit H2GT-14B321-AA do?

The airbag control unit H2GT-14B321-AA coordinates the SRS for Ford. It processes the signals from the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds in an accident.

The unit continuously checks whether all components are working. If it finds a fault, it reports it via the airbag warning light.

After an accident, it writes crash data, after which it is locked.

Why does the control unit H2GT-14B321-AA fail?

Crash data is the most common cause with the H2GT-14B321-AA, even when no airbag has fired. Other causes include ageing components, cold solder joints, moisture and voltage spikes.

Standard diagnostic tools cannot erase it, so it stays in memory.

The other causes affect the electronics themselves: components age and solder joints go cold. Moisture and corrosion at plug connectors lead to contact faults.

Voltage spikes arise, for example, from a weak battery or jump-starting, and can stress the electronics.

How can you tell that the H2GT-14B321-AA is defective?

A defect in the H2GT-14B321-AA shows up as the airbag warning light, error messages, a missing connection to the diagnostic tool or a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may fail to trigger in an emergency.

The airbag warning light in the instrument cluster stays on permanently or lights up only intermittently. The instrument cluster displays an error message for this.

A diagnostic tool that cannot make contact with the control unit, and a fault memory that persists despite an attempt to clear it, are further indications. In that case, have the system checked promptly.

Which vehicles is the H2GT-14B321-AA fitted in?

The H2GT-14B321-AA is fitted in these vehicles: Ford Edge 2 (2015-2024). Comparing the part number on the label with this page ensures you have the correct unit.

The following assignments are stored:

• Ford Edge 2 (2015-2024)

Two steps are involved: first compare the label, then have the fault memory read out. Only the read-out shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 7T4Z-14B321-BJ, DT4Z-14B321-A, DT4Z-14B321-B, E1GT-14B321-BE, H2GZ-14B321-A, K2GT 14B321 EB.

How does the repair of the H2GT-14B321-AA work?

At the start, the fault memory is read out with the enclosed log. Then you disconnect the battery and only then remove the control unit H2GT-14B321-AA. Online, you create the repair order and send in the carefully packed unit. Processing at Airbag24 usually takes 3–4 working days.

The sequence must be kept in every repair, because the restraint system can only be safely handled once the battery has been disconnected.

Airbag24 examines the unit on the test bench, replaces defective components, deletes crash data and carries out a function test. Your own unit then goes back 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 H2GT-14B321-AA get to Airbag24?

You send the control unit H2GT-14B321-AA off as a parcel or book a UPS collection for an extra charge. After the repair, UPS brings the unit back to you from Airbag24.

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