Airbag control unit with part number 6G13-14B321-AA

What does the airbag control unit 6G13-14B321-AA do?

The airbag control unit 6G13-14B321-AA controls the restraint system (SRS) of Ford. It checks the signals from the crash sensors, decides within milliseconds in the event of an accident whether airbags and seatbelt pretensioners are triggered, and reports faults to the airbag warning light.

The unit continuously monitors the sensors, wiring and trigger circuits, even when nothing noticeable happens.

After an accident it stores crash data and locks itself.

Why does the control unit 6G13-14B321-AA fail?

The most common cause is crash data from an earlier accident, even if no airbag was triggered. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

An ordinary diagnostic tool cannot remove stored crash data. Airbag24 takes care of this during the repair.

The other causes mainly concern the electronics themselves and their connections:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 6G13-14B321-AA is defective?

A defect shows itself through the airbag warning light in the instrument cluster, through an error message, through a missing connection to the diagnostic tool, or through a fault memory that cannot be cleared. In such cases the airbags and seatbelt pretensioners may not trigger in an emergency.

Typical signs in detail:

• The airbag warning light stays on or flickers at times.
• A warning message appears in the instrument cluster.
• The diagnostic tool cannot reach the control unit.
• The fault memory remains after an attempt to clear it.

The warning light is the most important warning sign, because it makes the fault visible at once. A missing connection to the diagnostic tool does not necessarily originate in the control unit; plugs and cables are also possible causes.

Compare the part number on the label of the removed unit with this page, and you will confirm that it is the right unit. Also have the fault memory read out beforehand, because only this log 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 5G13-14B321-CB, 5G13-14B321-DB, 6G13-14B321-BA, 6G13-14B321-BB, 7G13-14B321-BA, 7G13-14B321-FA.

How does the repair of the 6G13-14B321-AA work?

First you have the fault memory read out and attach the log, then you disconnect the battery before the control unit 6G13-14B321-AA is removed. Afterwards you create the repair order online and send in the well-packed unit. Processing at Airbag24 usually takes 3–4 working days.

The sequence is prescribed for safety reasons, because removal is only safe with the battery disconnected.

On the test bench Airbag24 examines the unit, repairs defective components, erases the crash data and carries out a function test.

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. Our repairs come with 2 years' statutory liability for defects.
