Airbag control unit with part number 9807575780

What does the airbag control unit 9807575780 do?

The airbag control unit 9807575780 forms the central control unit of the restraint system (SRS) in the vehicle for Peugeot. It evaluates the crash sensors, decides in an accident within fractions of a second on airbags and seatbelt pretensioners, and checks the system continuously.

The unit stores faults in the fault memory and shows them via the airbag warning light in the instrument cluster. After an accident it stores crash data and then locks itself. Only the repair lifts the lock.

Why does the control unit 9807575780 fail?

Most often, crash data stored after an accident leads to failure, even if no airbag has deployed. Other causes include ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase crash data. Airbag24 erases it during the repair of the 9807575780.

Electronics age, solder joints can go cold, and moisture attacks plug connections. A weak battery or jump-starting also introduces voltage spikes into the system.

How can you tell that the 9807575780 is defective?

A defect on the 9807575780 shows up as the airbag warning light, fault messages in the instrument cluster, a diagnostic tool without connection and a fault memory that cannot be cleared. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.

• The airbag warning light is lit permanently or intermittently.
• The instrument cluster shows a fault message.
• The diagnostic tool cannot find the control unit.
• The fault memory cannot be cleared.

The warning light shows the fault as soon as it occurs. Have the system checked on each of these indications.
