Airbag control unit with part number 9661440580

What does the airbag control unit 9661440580 do?

The airbag control unit 9661440580 is the central control unit of the restraint system (SRS) for Peugeot. It evaluates the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners to trigger, and monitors the system continuously.

The manufacturer number Bosch 0285001746 is also printed on the housing.

The unit reports faults via the airbag warning light. After an accident, it stores crash data and locks itself.

Why does the control unit 9661440580 fail?

The most common cause of the 9661440580 failing is crash data from an earlier accident, even if no airbag was triggered. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage peaks also contribute to failure.

Stored crash data cannot be erased with an ordinary diagnostic tool. Airbag24 erases it during the repair.

Electronics age, and solder joints can lose good contact over time. Moisture and corrosion at plug connections are another reason, because they disrupt the contact.

Voltage peaks, for example from a weak battery or a jump start, put additional strain on the electronics.

How can you tell that the 9661440580 is defective?

A defect in the 9661440580 can be recognised by the airbag warning light in the instrument cluster lighting up constantly or intermittently. Other signs include a fault message in the instrument cluster, no connection to the diagnostic tool, or a fault memory that cannot be cleared.

These signs are noticeable in everyday use:

• Airbag warning light lights up constantly or intermittently
• Fault message in the instrument cluster
• No connection can be made to the diagnostic tool
• The fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not trigger with such a defect. Therefore take the warning seriously.
