Airbag control unit with part number 670100884

What does the airbag control unit 670100884 do?

The airbag control unit 670100884 manages the SRS of Maserati. It checks the crash sensors continuously, decides in an accident within milliseconds on the deployment of airbags and seatbelt pretensioners, and indicates faults via the airbag warning light.

The manufacturer number Bosch 0285014315 is additionally printed on the housing.

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

Why does the control unit 670100884 fail?

Stored crash data from an accident is the most common cause, even when no airbag has deployed, and a normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes come on top.

A weak battery or jump-starting can cause voltage spikes that harm the electronics. Aged components and cold solder joints are further reasons that become noticeable in the unit over time.

Airbag24 erases the crash data during the repair. Which of the other causes is present is determined by the examination.

How can you tell that the 670100884 is defective?

A defect shows through the airbag warning light in the instrument cluster, which lights up constantly or at times, or through further signs in the instrument cluster. Then airbags and seatbelt pretensioners may fail to deploy in an emergency.

Typical signs are:

• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared

The warning light makes the fault visible, so have the system checked promptly when it lights up.
