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

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

The unit GV4T-14B321-BB controls the restraint system (SRS) of Ford. It measures via the crash sensors whether an accident has occurred, calculates within fractions of a second which airbags and seatbelt pretensioners are triggered, and monitors the entire system continuously.

The control unit indicates a fault in the system via the airbag warning light. After an accident it stores crash data and then locks itself.

As the core component of safety technology, it connects the sensors with the airbags.

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

With the GV4T-14B321-BB, the most common cause is the crash data that remains in the unit after an accident, even if no airbag was triggered. An ordinary diagnostic tool cannot remove it. Ageing, corrosion and electrical faults are further causes.

• aged components on the electronics
• cold or cracked solder joints
• moisture and corrosion at plug connections
• voltage spikes from the vehicle electrical system, for example with a weak battery or a jump start

Airbag24 removes the crash data during the repair. You do not have to try to erase it yourself.

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

On the GV4T-14B321-BB, the airbag warning light, error messages in the instrument cluster and the missing connection to the diagnostic tool are the main signs. A fault memory that cannot be cleared is also an indication.

These signs appear when there is a defect:

• airbag warning light stays on permanently or intermittently
• error message in the instrument cluster
• no connection from the diagnostic tool to the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then not trigger.
