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

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

The airbag control unit DG13-14B321-AF coordinates the restraint system (SRS) of Ford. From the crash sensor signals it calculates within a very short time which airbags and seatbelt pretensioners fire in an accident. At the same time, it monitors all the components involved and indicates faults via the airbag warning light.

This monitoring runs continuously in the background. The control unit stores any deviations found as fault entries, which a diagnostic tool can retrieve.

After an accident, the control unit creates crash data and locks itself. Only a repair lifts the lock.

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

The most common cause is the recording of crash data after an accident, even if no airbag has deployed. A diagnostic tool of the usual type cannot erase this data. Ageing electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes are also suspected.

Crash data stays in the memory until it is specifically removed, regardless of how the accident progressed.

Ageing electronics, cold solder joints and corrosion on plug connectors are among the typical reasons. Voltage spikes, for example from jump-starting, also act on the circuitry.

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

The airbag warning light in the instrument cluster lights up constantly or intermittently, and the instrument cluster displays an error message. The diagnostic tool does not connect to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may therefore fail to deploy in an emergency.

This light indicates that something is wrong in the restraint system. Whether the control unit itself is affected is determined by a specialist check.

The part number on the label counts when removing the unit. Comparing it with this page only shows that the right unit is at hand. Have the fault memory read out beforehand, as only this result shows whether the control unit is defective or a plug or cable is behind it.

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-AG.

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

First have the fault memory read out and add the log to the unit. Then disconnect the battery and remove the control unit. Next, create a repair order online and send the carefully packed unit to Airbag24.

The unit first goes onto the test bench. There, defective components are replaced, the crash data is erased and the function test is carried out. Afterwards the unit is returned to you. Processing at Airbag24 usually takes 3–4 working days.

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-AF get to Airbag24?

The unit goes to Airbag24 as a parcel, or you book a UPS collection for an extra charge. The return after the repair is made by UPS.

Enclose the printed repair order with the unit and pack the parcel shockproof.
