Airbag control unit with part number EB3T-14B321-EG

What does the airbag control unit EB3T-14B321-EG do?

The control unit EB3T-14B321-EG is the control unit of the restraint system (SRS) at Ford. From the signals of the crash sensors it calculates within milliseconds in an accident which airbags and seatbelt pretensioners to trigger, and it monitors the system constantly. If it detects a fault, it reports it via the airbag warning light.

Monitoring runs in the background, regardless of driving or standstill.

After an accident the unit stores crash data and locks itself.

Why does the control unit EB3T-14B321-EG fail?

The most common cause in the EB3T-14B321-EG is crash data stored after an accident, even if no airbag has deployed. A commercially available diagnostic tool cannot erase this data. Added to this are aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes from weak batteries or jump-starting.

The data is created regardless of whether an airbag has fired.

The other causes lie in the electronics and their surroundings. Components age, solder joints can go cold, and moisture makes contacts corrode. Airbag24 erases the crash data during the repair.

How can you tell that the EB3T-14B321-EG is defective?

On the EB3T-14B321-EG, a fault shows up through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. The instrument cluster also displays a fault message, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be erased.

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory cannot be erased

Such signs point to a fault in the restraint system.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

You can make the label comparison with this page; it only confirms the identity of the unit. Beforehand have the fault memory read out; only its result decides whether the control unit is defective or whether a plug or cable is behind it.

For the same vehicles, we also repair control units with the part numbers AB3914B321CF, KB3T-14B321-BD.

How does the repair of the EB3T-14B321-EG work?

For the repair of the EB3T-14B321-EG, have the fault memory read out beforehand, enclose the log, and only after disconnecting the battery remove the control unit. Then create the repair order online and send in the well-packed unit. Airbag24 needs 3–4 working days as a rule for checking, repairing and testing.

At Airbag24 the unit is inspected on the test bench, defective components are repaired and the crash data erased. Only then does a function test follow, after which your own unit is returned to you.

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.
