What does the airbag control unit E3B5-14B321-AC do?
The airbag control unit E3B5-14B321-AC controls the restraint system (SRS) of Ford. It evaluates the signals from the crash sensors, decides within milliseconds in an emergency whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.
The unit shows faults via the airbag warning light. After an accident it stores crash data and locks itself.
Why does the control unit E3B5-14B321-AC fail?
The most common cause is crash data stored after an accident, even if no airbag has deployed. Further causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, for example from a weak battery or a jump start.
A normal diagnostic tool cannot erase this crash data. The other causes tend to develop over time: solder joints can give way, electronics age, and moisture attacks plug connections.
How can you tell that the E3B5-14B321-AC is defective?
The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears in the instrument cluster. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.
The warning light is the signal the system gives itself. Take it seriously and have the system checked promptly.
