Airbag control unit with part number 626181300

What does the airbag control unit 626181300 do?

The airbag control unit 626181300 is the central control unit of the restraint system (SRS) for Citroën and Peugeot. It evaluates signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered. It monitors the system continuously and indicates faults via the airbag warning light.

The monitoring runs in the background throughout all operation. In doing so, sensors, wiring and actuation are checked.

After an accident, the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 626181300 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Further causes that may come into consideration are briefly listed below:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Which of these causes applies can only be narrowed down by reading out the fault memory and the subsequent check.

Airbag24 erases the crash data during the repair, so this point is settled with the order.

How can you tell that the 626181300 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears there. The diagnostic tool cannot connect to the control unit, and a fault memory cannot be cleared.

Airbags and seatbelt pretensioners may not be able to deploy in an emergency while the indication persists. The warning light should therefore be checked promptly.
