Airbag control unit with part number 68085881AF

What does the airbag control unit 68085881AF do?

The airbag control unit 68085881AF is the central control unit of the restraint system (SRS) for Dodge. It evaluates the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. It shows detected faults via the airbag warning light.

Monitoring continues in the background. The unit checks sensors, wiring and its own function and stores faults in the fault memory.

After an accident it stores crash data and then locks itself.

Why does the control unit 68085881AF fail?

The most common cause of a fault in the 68085881AF is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump starting.

Airbag24 erases the crash data during the repair. The other causes concern the electronics themselves: components age, solder joints can be cold, and moisture attacks plug connections.

How can you tell that the 68085881AF is defective?

A fault in the 68085881AF shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, through an error message in the instrument cluster, through a lack of connection from the diagnostic tool, or through a fault memory that cannot be erased. Airbags and seatbelt pretensioners may then fail to trigger in an emergency.

The warning light is the most important warning sign. Have it checked promptly.

A diagnostic tool reads out the fault memory and makes the reported fault traceable.
