Airbag control unit with part number 0285 001 349

What does the airbag control unit 0285 001 349 do?

The airbag control unit 0285 001 349 is the central control unit of the restraint system (SRS) for Ford. It processes the crash sensor signals and decides in the event of an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

During operation it checks the system continuously. A detected fault appears via the airbag warning light in the instrument cluster.

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

Why does the control unit 0285 001 349 fail?

Stored crash data is the most common cause, even without a triggered airbag; it cannot be erased with a normal diagnostic tool. Other causes include aged components, moisture, corrosion and voltage spikes.

The crash data remains in the unit even when the vehicle is driving again. Airbag24 erases it during the repair.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example with a weak battery or a jump start

Which of the other causes applies only becomes clear during the inspection.

How can you tell that the 0285 001 349 is defective?

You can recognise a defect on the 0285 001 349 by the airbag warning light, fault messages in the instrument cluster, a diagnostic tool without connection and a fault memory that cannot be cleared.

The airbag warning light in the instrument cluster stays on permanently or intermittently. It is the most important indication and shows the defect as soon as the control unit detects it. This may be accompanied by a fault message.

In an emergency, airbags and seatbelt pretensioners may fail to trigger while the fault persists. Therefore have the system checked promptly.
