Airbag control unit with part number 670153626

What does the airbag control unit 670153626 do?

The airbag control unit 670153626 is the central control unit of the restraint system at Maserati. It evaluates the crash sensors, decides in an accident within fractions of a second which airbags and seatbelt pretensioners fire, and monitors the entire system.

The unit additionally carries the number Bosch 0285015487 on its housing. If it detects a fault, it displays it via the airbag warning light in the instrument cluster.

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

Why does the control unit 670153626 fail?

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

Stored crash data cannot be erased with a normal diagnostic tool. Airbag24 clears it during the repair.

The other causes concern the electronics. Components wear out, solder joints can go cold, and moisture or corrosion at the plugs impairs the contact. A weak battery or a jump start can also damage the unit through voltage spikes.

How can you tell that the 670153626 is defective?

A defect in the 670153626 can be recognised by several signs. The most obvious is the airbag warning light, which lights up permanently or intermittently.

• The airbag warning light lights up permanently or intermittently.
• An error message appears in the instrument cluster.
• A diagnostic tool gets no connection to the control unit.
• The fault memory cannot be cleared.

While the light is on, airbags and seatbelt pretensioners may not fire in an emergency. A light that goes out therefore does not automatically mean that the fault has disappeared.
