Airbag control unit with part number 8G13-14B321-AD

What does the airbag control unit 8G13-14B321-AD do?

The airbag control unit 8G13-14B321-AD is the control unit of the restraint system (SRS) for Ford. In an accident it calculates from the values of the crash sensors which airbags and seatbelt pretensioners are triggered, and this happens within milliseconds. During operation it checks the system continuously and reports faults via the airbag warning light.

After an accident, the unit stores crash data and locks itself. This process is firmly anchored in the system.

Without this central evaluation, airbags and seatbelt pretensioners could not be controlled reliably.

Why does the control unit 8G13-14B321-AD fail?

The most common cause is crash data stored after an accident, even without an airbag being triggered, which cannot be removed with a normal diagnostic tool. Aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes such as with a weak battery or a jump start can also lead to failure.

Crash data is therefore the most important point before considering other causes. Only after that do the electronics and plug connectors come into question.

Whether one of these causes is present in the individual case is only shown by the test of the unit.

How can you tell that the 8G13-14B321-AD is defective?

Signs are an airbag warning light that is permanently or intermittently on, an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be erased. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

These signs usually appear together, and each of them is a reason for a test.

Typical signs at a glance:

• airbag warning light permanently or intermittently on
• error message in the instrument cluster
• no connection to the diagnostic tool
• fault memory cannot be erased

• Ford Taurus 5 (2008-2009)

Compare the part number on the label of the unit with this page; that only tells you that it is the right unit. You should have the fault memory read out beforehand, because only this result shows whether the control unit is defective or a plug or cable is the cause.

How does the repair of the 8G13-14B321-AD work?

First have the fault memory read out and enclose the printout. Then disconnect the battery and only then remove the control unit; finally, create a repair order online and send the unit in well packed.

This order protects you and must be followed without exception when handling the restraint system.

Airbag24 tests the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Afterwards, your own unit is returned. 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 8G13-14B321-AD get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.

Put the printed repair order into the parcel and pack the unit shock-proof.
