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

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

The airbag control unit DG13-14B321-AJ is the central control unit of the restraint system of Ford. It reads the signals from the impact sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners trigger, and monitors the system continuously.

The unit indicates detected faults via the airbag warning light. After an accident it stores crash data and locks itself, and only the repair lifts this lock.

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

Crash data stored after an accident is the most common cause for the DG13-14B321-AJ, even if no airbag has deployed. Standard diagnostic tools cannot erase it; further causes are ageing components, cold solder joints, moisture and voltage spikes.

How much each factor contributes cannot be judged from outside. Only evaluating the fault memory provides information on this.

Moisture and corrosion mainly attack plug connections, while voltage spikes arise, for example, from a weak battery or jump-starting.

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

A defect in the DG13-14B321-AJ becomes visible on the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Also present are an error message in the instrument cluster, a missing connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may not be able to deploy. A finding like this should therefore be checked promptly.

Before removal there are two important steps. First, compare the part number on the label of the unit with this page; this only confirms that it is the correct unit. Second, have the fault memory read out, because only this 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 AG13-14B321-AD, AG1Z-14B321-A, AG1Z-14B321-B, BG13-14B321-AB, DG13-14B321-AD, DG13-14B321-AF.

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

Airbag24 needs 3–4 working days in the normal course for testing, repair and function test. In the process, the team tests the unit on the test bench, repairs defective components and erases the stored crash data.

On your side, first have the fault memory read out with the log enclosed, then disconnect the battery and only then remove the unit. Create the repair order online and send the unit in.

After the function test, your own unit comes 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 DG13-14B321-AJ get to Airbag24?

You send the DG13-14B321-AJ as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns the unit by UPS.

The printed repair order belongs in the parcel. Pack the control unit shockproof before it goes on its way.
