Airbag control unit with part number 9674291780

What does the airbag control unit 9674291780 do?

The airbag control unit 9674291780 is the central control unit of the restraint system (SRS) for Peugeot. It processes the signals from the crash sensors and decides within milliseconds in a crash which airbags and seatbelt pretensioners are triggered.

While driving, it monitors the system without interruption. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 9674291780 fail?

The 9674291780 most often fails because crash data was stored after a crash, even if no airbag was triggered. A normal diagnostic tool cannot erase this data.

Storage does not depend on whether airbags were triggered. It therefore belongs at the beginning of this overview.

Aged electronic components, which gradually lose reliability over time, also play a role. Cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start, are likewise possible.

How can you tell that the 9674291780 is defective?

The airbag warning light in the instrument cluster indicates a defect in the 9674291780 by lighting up constantly or intermittently. You should also watch for further signs.

These signs can occur:

• The airbag warning light stays on constantly.
• It lights up only intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool finds no connection to the control unit.
• The fault memory cannot be erased.

If several of these signs appear, you should clarify the cause promptly. In an emergency, airbags and seatbelt pretensioners may possibly fail to deploy while the fault persists.
