Airbag control unit with part number 1671163680

What does the airbag control unit 1671163680 do?

The airbag control unit 1671163680 controls the restraint system (SRS) of DS Automobiles and evaluates the signals from the crash sensors. In an accident it decides within a very short time which airbags and seatbelt pretensioners are triggered.

During operation it checks the system, and it shows faults via the airbag warning light in the instrument cluster. This way you learn of a fault without having to measure anything yourself.

After an accident it stores crash data and locks itself. The lock is an integral part of how the unit works.

Why does the control unit 1671163680 fail?

Stored crash data is the most common cause, even if no airbag has deployed. Added to this are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as those from a weak battery or jump-starting.

Crash data cannot be erased with a normal diagnostic tool, so the entry remains in the unit. The message repeats until the repair removes it.

The other causes affect contacts and components that you cannot inspect from outside. Airbag24 erases the crash data during the repair and checks the other points on the unit itself.

How can you tell that the 1671163680 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not deploy.

These signs are hard to miss if you keep an eye on the displays in the instrument cluster. The warning light is a clear signal and should be checked promptly.
