Airbag control unit with part number GV4T-14B321-AC

What does the airbag control unit GV4T-14B321-AC do?

Within the restraint system (SRS) of Ford, the airbag control unit GV4T-14B321-AC is the central control unit. It processes the signals from the crash sensors, and in the event of an accident it triggers the appropriate airbags and seatbelt pretensioners within milliseconds. After an accident it stores crash data and locks itself.

At the same time it checks itself and the connected components. If it detects a fault, it alerts the driver via the airbag warning light in the instrument cluster.

Why does the control unit GV4T-14B321-AC fail?

With the GV4T-14B321-AC, crash data stored in the unit after an accident is the primary cause, even if no airbag has deployed. A normal diagnostic tool cannot remove it. Ageing components, moisture and voltage spikes are further causes.

Airbag24 removes this data only as part of the repair.

The other causes are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery.

How can you tell that the GV4T-14B321-AC is defective?

A defect in the GV4T-14B321-AC shows first at the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Further indications are given by the messages in the instrument cluster and the connection to the diagnostic tool.

These signs can occur individually or together:

• Error message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory cannot be cleared

As a result, the airbags and seatbelt pretensioners may not deploy in an emergency. Do not delay the check.

Which vehicles is the GV4T-14B321-AC fitted in?

The GV4T-14B321-AC was fitted in these vehicles with Ford: Ford Kuga 2 ’13 (2012-2016) and 2 ’13 Facelift (2016-2019).

The assignment is listed here:

• Ford Kuga 2 ’13 (2012-2016)
• Ford Kuga 2 ’13 Facelift (2016-2019)

Matching the number on the label of the removed unit with this page only confirms the identity of the unit. Before removal you should therefore have the fault memory read out, because only it shows whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285012044, 6E5T15607CA, 8M5T14B342AC, 9V4T-14B321-AB, CJ5T14B321AG, CV4T 14B321 CG.

How does the repair of the GV4T-14B321-AC work?

For the repair of the GV4T-14B321-AC, first have the fault memory read out and attach the log. Then disconnect the battery, and only after that remove the control unit. Next you create a repair order online and send in the well-packed unit.

Airbag24 checks the unit on the test bench, repairs defective components, erases stored crash data and carries out a functional test. At Airbag24, processing 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.
