Airbag control unit with part number K2GT-14B321-GA

What does the airbag control unit K2GT-14B321-GA do?

The airbag control unit K2GT-14B321-GA is the central control unit of the SRS restraint system in Ford. It reads the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If it detects a fault, it shows it via the airbag warning light in the instrument cluster. The monitoring runs constantly in the background.

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

Why does the control unit K2GT-14B321-GA fail?

The most common cause for the control unit K2GT-14B321-GA is crash data stored after an accident, even if no airbag has deployed. A standard diagnostic tool does not delete it. Other causes are aged components, cold solder joints, moisture and voltage spikes.

The other causes in summary:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the K2GT-14B321-GA is defective?
