Airbag control unit with part number GN15-14B321-KA

What does the airbag control unit GN15-14B321-KA do?

In Ford vehicles, the airbag control unit GN15-14B321-KA controls the restraint system: it checks the crash sensors, selects the airbags and seatbelt pretensioners that fire in a crash, and monitors the system continuously.

The decision is made within milliseconds. If the unit detects a fault, the airbag warning light in the instrument cluster comes on.

After a crash, the unit stores crash data and then locks itself. It can only be unlocked by a repair.

Why does the control unit GN15-14B321-KA fail?

The most common cause is crash data stored after an accident, even if no airbag has fired; a normal diagnostic tool cannot erase it. Ageing components, soldered joints, moisture and voltage spikes also play a part.

Airbag24 erases this data during the repair. The other causes at a glance:

• Electronics whose components are ageing
• Soldered joints that are not properly connected
• Plug connections affected by moisture or corrosion
• Voltage spikes, for example from a weakened battery or a jump start

How can you tell that the GN15-14B321-KA is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool cannot connect to the GN15-14B321-KA, and the fault memory cannot be cleared.

Such a finding means that airbags and seatbelt pretensioners may not deploy in an emergency. The warning light should therefore be taken seriously.

Reading out the fault memory shows whether the control unit itself is affected.
