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

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

The airbag control unit GN15-14B321-GH organises the restraint system (SRS) of Ford. It evaluates the sensor signals, calculates the triggering in a crash within milliseconds and monitors the system continuously.

If it detects a fault, it reports it via the airbag warning light in the instrument cluster.

If an accident has occurred, the control unit stores crash data and locks itself. The lock is lifted only by the repair.

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

Crash data from an earlier accident is the most common cause, even if no airbag has deployed. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be removed with a normal diagnostic tool. Airbag24 erases it during the repair.

The other causes concern the condition of the electronics and the contacts, including fluctuations in current.

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

An airbag warning light in the instrument cluster that stays on permanently or intermittently indicates a defect in the GN15-14B321-GH. Fault messages, a missing connection to the diagnostic tool, or a fault memory that cannot be cleared are further signs.

In that case, the airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light is a direct signal from the system itself, and ignoring it would be a considerable risk.

You can carry out the label comparison with this page; it only confirms the unit number. The cause is determined solely by the fault memory, which you should have read out before removal. Only this reading shows whether the control unit is defective or whether plugs or cables are affected.

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-GH work?

First, have the fault memory read out and enclose the log. Then disconnect the battery and only afterwards remove the control unit.

Then create a repair order online and pack the control unit well before you send it in.

Airbag24 checks the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. Processing usually takes 3–4 working days at Airbag24. Your own unit is then sent 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 GN15-14B321-GH get to Airbag24?

Either you send the unit as a parcel, or you book a UPS collection for an extra charge. The return after the repair goes by UPS.

Place the printed repair order in the parcel and protect the unit against shocks.
