Airbag control unit with part number DG13-14B321-AD

What does the airbag control unit DG13-14B321-AD do?

The airbag control unit DG13-14B321-AD coordinates the restraint system (SRS) in Ford vehicles. From the readings of the crash sensors, it determines whether and which airbags and seatbelt pretensioners fire in an accident.

The evaluation takes place within milliseconds. In the background, the control unit continuously checks the lines and components of the system and shows faults via the airbag warning light.

If an accident places a heavy load on the crash sensors, the unit stores data and then blocks further use of the system. Only a repair lifts this block.

Why does the control unit DG13-14B321-AD fail?

The most common cause is crash data stored after an accident, even if no airbag fired. Further triggers are ageing electronics, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Crash data cannot be removed with an ordinary diagnostic tool. At Airbag24, it is deleted as part of the repair.

Electronics age, even without any accident. Solder joints can become cold over time or crack, and moisture and corrosion on plug connectors lead to contact problems.

Voltage spikes occur, for example, with a weak battery or when a jump start is connected. This load can also damage components.

How can you tell that the DG13-14B321-AD is defective?

Typical signs are an airbag warning light that stays on permanently or only now and then, as well as an error message in the instrument cluster. In addition, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

• The airbag warning light stays on permanently in the instrument cluster.
• The warning light only appears intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot find the control unit.
• The fault memory remains even after an attempt to clear it.

If you see any of these signs, airbags and seatbelt pretensioners may not trigger in an emergency. Please keep an eye on them.

The warning light shows the fault as soon as the control unit notices it. A prompt workshop visit is therefore sensible.

Compare the part number on the label of the removed unit with this page, so that you can be sure you have the right unit in front of you.

Have the fault memory read out before removal. Only then will it become clear 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 AG13-14B321-AD, AG1Z-14B321-A, AG1Z-14B321-B, BG13-14B321-AB, DG13-14B321-AF, DG13-14B321-AG.

How does the repair of the DG13-14B321-AD work?

First have the fault memory read out and enclose the log with the unit. Then disconnect the battery, remove the control unit and create the repair order online. Airbag24 usually processes the unit within 3–4 working days.

So you start by reading out the fault memory. Only once the battery is disconnected may the control unit come out of the vehicle. Then pack it carefully and send it in.

At Airbag24, the unit is examined on the test bench. Defective components are repaired, the crash data is deleted and a function test is carried out. Afterwards, you get your own unit back.

The 3–4 working days refer solely to checking, repair and testing at Airbag24, not to the steps before or after.

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 DG13-14B321-AD get to Airbag24?

You send the control unit DG13-14B321-AD to Airbag24 as a parcel, or you book a UPS collection. After the repair, UPS brings the unit back to you.

The printed repair order goes into the parcel. Pack the unit shock-proof.
