Airbag control unit with part number A1679005718

What does the airbag control unit A1679005718 do?

The airbag control unit A1679005718 is the control unit of the restraint system (SRS) at Mercedes-Benz. It evaluates the crash sensors, decides within milliseconds in an accident on airbags and seatbelt pretensioners, and monitors the system continuously. It shows faults via the airbag warning light.

The manufacturer's part number Bosch 0285015860 is also printed on the housing.

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

Why does the control unit A1679005718 fail?

The most common cause is stored crash data on the control unit A1679005718, even if no airbag has fired; a normal diagnostic tool cannot erase it. Other causes lie in the electronics and in the connections.

Airbag24 erases the crash data during the repair.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes when starting with jump leads

How can you tell that the A1679005718 is defective?

A defect on the control unit A1679005718 shows up as the airbag warning light in the instrument cluster, which stays on constantly or intermittently. In addition there is an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be erased.

As long as the warning is active, airbags and seatbelt pretensioners may not trigger in an emergency. The light is therefore a clear signal that must not be ignored.

Arrange for the fault memory to be read out promptly.
