Airbag control unit with part number 98AG14B056ACE

What does the airbag control unit 98AG14B056ACE do?

The airbag control unit 98AG14B056ACE is the control unit of the restraint system (SRS) in Ford. It processes the signals from the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds of an accident.

Outside an accident it constantly monitors the system's components. If it detects a fault, the airbag warning light in the instrument cluster comes on.

In the event of an accident, the unit stores crash data and then locks itself.

Why does the control unit 98AG14B056ACE fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed. A standard diagnostic tool cannot erase this data. Further causes from the electronics come on top of that.

The further causes include:

• ageing of electronic components
• dry solder joints in the control unit
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 98AG14B056ACE is defective?

A defect shows up as the airbag warning light, an error message in the instrument cluster, the diagnostic tool failing to connect, and a fault memory that cannot be erased. A single one of these signs justifies an inspection.

The airbag warning light stays on permanently or only intermittently as soon as something in the system is wrong. While the light is on, airbags and seatbelt pretensioners may not trigger in an emergency. Do not wait; have the cause clarified.
