Airbag control unit with part number 0285010702

What does the airbag control unit 0285010702 do?

As the control centre of the restraint system (SRS) in Peugeot, the airbag control unit 0285010702 records the signals of the crash sensors. Within milliseconds it decides on airbags and seatbelt pretensioners and monitors the system continuously. After an accident it stores crash data and locks itself.

The system remains under constant observation during operation. Irregularities appear in the fault memory and on the airbag warning light.

Why does the control unit 0285010702 fail?

The most common cause is stored crash data after an accident, even without a deployed airbag; a normal diagnostic tool cannot erase it. Ageing electronics, cold solder joints, moisture and corrosion on connectors, and voltage spikes are also possible causes.

After the accident the unit retains the crash data. The data stays until Airbag24 removes it during the repair.

Further causes are, in detail:

• ageing of the electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 0285010702 is defective?

A defect is first noticed at the airbag warning light in the instrument cluster: it lights up permanently or intermittently. An error message accompanies it, and the diagnostic tool does not find the control unit. A fault memory also cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The warning light is not a detail that can be overlooked. It reports the defect at the moment the control unit detects it.

In addition, the diagnostic tool gets no contact with the control unit, and a fault memory cannot be cleared.
