Airbag control unit with part number 9633474180

What does the airbag control unit 9633474180 do?

The airbag control unit 9633474180 takes over control of the restraint system (SRS) of Peugeot. Using the crash sensors it recognises an accident and, within fractions of a second, decides which airbags and seatbelt pretensioners are triggered.

This includes continuous monitoring of the system. Faults are shown via the airbag warning light in the instrument cluster.

After an accident it records crash data and locks itself.

Why does the control unit 9633474180 fail?

The most common cause: crash data stored after an accident, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. Which of the other causes is present is shown only by testing.

Voltage spikes occur, for example, from a weak battery or a jump start. Moisture and corrosion attack the contacts of the plugs, which can then cause faults.

How can you tell that the 9633474180 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. An error message accompanies it, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

As long as these signs persist, airbags and seatbelt pretensioners may not trigger in an emergency.

The warning light is therefore a signal to have the system checked promptly.

Comparing the part number on the label of the removed unit with this page confirms that you have the right unit. The cause, however, is only clarified by reading out the fault memory, because it shows whether the control unit itself is defective or whether a plug or cable is the cause. Therefore have the fault memory read out beforehand.
