Airbag control unit with part number E1GT-14B321-CC

What does the airbag control unit E1GT-14B321-CC do?

The airbag control unit E1GT-14B321-CC coordinates the airbags and seatbelt pretensioners of Ford. In an impact it compares the sensor readings and triggers the appropriate restraint devices within fractions of a second. It also checks the system continuously and shows faults on the airbag warning light.

If the control unit has registered an accident, it stores crash data and then locks itself. The lock is only lifted by a repair.

In normal operation the unit is barely noticeable. Its job only becomes apparent in an emergency, which is why it is all the more important that it makes faults visible.

Why does the control unit E1GT-14B321-CC fail?

Crash data from an accident, even without a triggered airbag, is the most common cause of a failure. An ordinary diagnostic tool cannot erase it. Further triggers are aged electronic components, cold solder joints, moisture or corrosion at connectors, and voltage spikes from a weak battery or jump start.

That crash data is stored even without visible damage and without a triggered airbag is surprising to vehicle owners.

The other causes tend to creep in. Moisture and corrosion worsen contacts over the years, and a voltage spike can set a fault that then persists.

How can you tell that the E1GT-14B321-CC is defective?

Signs are things you can observe yourself: the airbag warning light in the instrument cluster is lit, fault messages appear, the diagnostic tool does not find the control unit, or the fault memory stays full despite an attempt to erase it. In an emergency, airbags and seatbelt pretensioners may then fail to fire.

The signs in detail:

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

Such signs cannot be waited out. The warning light reports a fault that already exists and does not wait for the next check.

Which vehicles is the E1GT-14B321-CC fitted in?

The E1GT-14B321-CC is fitted in these vehicles: Ford S-Max 2 (2015-2019) and 2 Facelift (2019-2023).

The vehicles from our assignment of this control unit are listed here.

• Ford S-Max 2 (2015-2019)
• Ford S-Max 2 Facelift (2019-2023)

Comparing the part number on the label of the removed unit with this page only confirms that the unit is the right one. Have the fault memory read out before removal, because only this log shows whether the control unit itself is defective or whether a connector or cable is causing the fault.

For the same vehicles, we also repair control units with the part numbers 6M2T-14B056-AE, AM2T-14B321-AC, BM2T-14B321-AB, BM2T-14B321-AC, BM5T-14B321-CE, E1GT 14B321 BF.

How does the repair of the E1GT-14B321-CC work?

The process begins with reading out the fault memory, and you enclose the log with the unit. Then disconnect the battery, remove the control unit and create the repair order online. At Airbag24, testing and repair usually take 3–4 working days.

Airbag24 tests the unit on the test bench, replaces damaged components, erases the stored crash data and checks the function. Afterwards your unit comes back 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.

How does the control unit E1GT-14B321-CC get to Airbag24?

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

The printed repair order belongs in the parcel, and the control unit needs shock-resistant packaging.
