Airbag control unit with part number GN15-14B321-EE

What does the airbag control unit GN15-14B321-EE do?

At Ford, the airbag control unit GN15-14B321-EE controls the entire restraint system (SRS). From the measurements of the crash sensors, it calculates within milliseconds which airbags and seatbelt pretensioners to trigger.

While driving, it checks all components and shows faults via the airbag warning light.

If an accident has occurred, the unit stores crash data and is locked afterwards.

Why does the control unit GN15-14B321-EE fail?

Crash data from an accident is the most common reason for the GN15-14B321-EE to fail, even if no airbag was triggered. Ordinary diagnostic tools cannot erase this data. Further causes are ageing components, cold solder joints, moisture and corrosion on plug connections, as well as voltage spikes, for example from a weak battery or a jump start.

The data remains in the memory until it is removed during the repair. As long as this is the case, the fault stays in the system, even if all other parts are in order.

The other causes build up over years. Electronics age, solder joints become brittle, and moisture attacks the plugs. Voltage spikes, by contrast, are short-term, for example from a weak battery or a jump start.

How can you tell that the GN15-14B321-EE is defective?

A defect in the GN15-14B321-EE shows up mainly on the airbag warning light, which stays on permanently or intermittently in the instrument cluster. Add to that fault messages, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then not trigger. Such signs should therefore be treated as a case to check.

Which vehicles is the GN15-14B321-EE fitted in?

First compare the part number on the label of the removed unit with this page. That only confirms the identity of the unit. Then have the fault memory read out, because only that result 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 DN1T-14B321-EC, GN15-14B321-AF, GN15-14B321-GJ, GN1Z-14B321-AE, GN1Z-14B321-AK.

How does the repair of the GN15-14B321-EE work?

At Airbag24, processing usually takes 3–4 working days. Before that, have the fault memory read out, disconnect the battery and remove the GN15-14B321-EE. Then create a repair order online and send the unit well packed.

Airbag24 checks the unit on the test bench, replaces defective components, erases the crash data and carries out a function test.

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 GN15-14B321-EE get to Airbag24?

You send the GN15-14B321-EE to Airbag24 as a parcel or book a UPS collection for an extra charge. Airbag24 sends the unit back by UPS after the repair.

The printed repair order goes into the parcel, and the unit is packed shock-proof.
