Airbag control unit with part number 9653441880

What does the airbag control unit 9653441880 do?

In the vehicle, the airbag control unit 9653441880 acts as the centre of the restraint system (SRS) of Peugeot. It evaluates the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners to trigger, and monitors the system without a break.

At the same time, it checks the connections to sensors and deployment elements. If it detects a fault, it saves it in memory and displays it.

After an accident, the control unit stores crash data and locks itself.

Why does the control unit 9653441880 fail?

Most common cause: crash data from an accident, even without a deployed airbag. A normal diagnostic tool cannot remove them. Other possible causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Electronic components are subject to ageing, and contacts can corrode over time.

Cold solder joints and moisture at plug connections lead to contact faults. Voltage spikes, for example from a weak battery or a jump start, can additionally disrupt the unit.

How can you tell that the 9653441880 is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently, and a fault message appears in the instrument cluster. If the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared, this indicates a defect; in an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The light is only a starting point for deciding on the cause. The message indicates a fault without assigning it to a component.

Only a readout shows which entries are in the fault memory. Then it becomes clear whether the control unit is affected.

Compare the part number on the label of the removed unit with this page. That only confirms that it is the right unit. Before that, have the fault memory read out, because only the log shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 550 54 15 00, 602 32 73 00, 6547WJ, 9635268880, 9636894080, 9641478080.

How does the repair of the 9653441880 work?

First have the fault memory read out and enclose the log with the parcel; then disconnect the battery and remove the control unit. Then create the repair order online and pack the unit carefully. Airbag24 checks it on the test bench, replaces defective components, erases the stored crash data and carries out a function test; afterwards your own unit is returned.

The sequence of steps is fixed: the control unit is removed only after the fault memory has been read out and the battery disconnected.

Airbag24 needs 3–4 working days in general for checking, repairing and testing. That time has nothing to do with removal or dispatch.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 9653441880 get to Airbag24?

Either you send the unit off as a parcel, or you book a UPS collection for an extra charge. After the repair, Airbag24 returns the repaired unit to you by UPS.

The printed repair order goes into the parcel. Pack the unit shock-resistant so that it survives transport undamaged.
