Airbag control unit with part number E1GT-14B321-BD

What does the airbag control unit E1GT-14B321-BD do?

The airbag control unit E1GT-14B321-BD coordinates the SRS restraint system of Ford. It receives the messages from the impact sensors, decides in an accident which airbags and seatbelt pretensioners are triggered, and checks the remaining components. Detected faults are shown via the airbag warning light.

If the control unit stores crash data after an accident, it locks itself. The lock only ends with the repair.

In normal operation you notice nothing of the control unit. Its work only becomes noticeable when it reports a fault.

Why does the control unit E1GT-14B321-BD fail?

Crash data from an accident, even without a triggered airbag, is the most common cause of a failure. Common diagnostic tools cannot remove it. Other causes are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

Crash data remains in the unit until it is repaired. A fault that results from it therefore does not disappear on its own.

The other causes work over a longer period. Ageing and corrosion gradually worsen contacts, and a brief voltage dip, for example from a weak battery, can leave a fault behind.

How can you tell that the E1GT-14B321-BD is defective?

Signs of a defect are the airbag warning light in the instrument cluster, which stays on continuously or only intermittently, error messages in the instrument cluster, a diagnostic tool without a connection to the control unit, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light is the clearest signal the vehicle gives you. It does not name the fault more precisely, but it shows that something is wrong in the restraint system.

If a fault cannot be eliminated despite repetition, the cause lies in the unit or the wiring and must be checked.

Comparing the part number on the label of the removed unit with this page confirms that you have the correct unit. The fault memory is read out beforehand; only this log shows whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 6M2T-14B056-AE, AM2T-14B321-AC, BM2T-14B321-AB, BM2T-14B321-AC, BM5T-14B321-CE, E1GT 14B321 BF.

How does the repair of the E1GT-14B321-BD work?

First have the fault memory read out and enclose the log. Then disconnect the battery, remove the control unit and create a repair order online. Airbag24 generally needs 3–4 working days for inspection, repair and functional testing.

On the test bench Airbag24 inspects the control unit you sent in, replaces defective components, erases the crash data and carries out a functional test. You then receive your own unit back.

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 E1GT-14B321-BD get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. After the repair Airbag24 sends the control unit back to you by UPS.

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