Airbag control unit with part number G1B5-14B321-AB

What does the airbag control unit G1B5-14B321-AB do?

The airbag control unit G1B5-14B321-AB belongs to the restraint system (SRS) of Ford. It evaluates the signals of the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners trigger, and monitors the system continuously. It shows faults via the airbag warning light.

After an accident it stores crash data and locks itself.

Without an accident, the monitoring runs unobtrusively in the background.

Why does the control unit G1B5-14B321-AB fail?

Most often the cause is crash data stored after an accident, even if no airbag has deployed; an ordinary reading tool does not remove this storage. Other causes are ageing, cold solder joints, moisture and corrosion, and voltage spikes.

Airbag24 erases the crash data during the repair. Until then, they remain in the control unit.

The remaining causes concern the electronics and their surroundings. Components age, solder joints can be cold, and moisture attacks the contacts.

Voltage spikes occur, for example, with a weak battery or when starting with a jump start, and they stress the circuits.

How can you tell that the G1B5-14B321-AB is defective?

A defect first shows up through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. At the same time a fault message appears there, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

If one of these signs occurs, have the system checked. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

Only the evaluation of the fault memory shows whether the control unit itself is affected.

Which vehicles is the G1B5-14B321-AB fitted in?

The control unit G1B5-14B321-AB is fitted in these vehicles: Ford Ka+ 3 (2016-2018) and 3 Facelift (2018-2021). Check your car against this information before you remove anything.

The vehicles for this part number:

• Ford Ka+ 3 (2016-2018)
• Ford Ka+ 3 Facelift (2018-2021)

Compare the part number on the label of the removed unit with this page; that only confirms it is the right unit. Regardless, have the fault memory read out, because only this result shows whether the control unit is defective or a connector or cable is the cause.

How does the repair of the G1B5-14B321-AB work?

First have the fault memory read out and enclose the log; only then disconnect the battery and remove the control unit. Afterwards create a repair order online and pack the unit well before sending it. Airbag24 checks it on the test bench, eliminates the damage to the components, erases the crash data and performs a function test before your own unit goes back.

The order is set for your safety. Processing at Airbag24 usually takes 3–4 working days and covers only checking, repairing and testing.

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 G1B5-14B321-AB get to Airbag24?

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

Put the printed repair order into the parcel and pack the unit shockproof.
