Airbag control unit with part number 68085880AG

What does the airbag control unit 68085880AG do?

The airbag control unit 68085880AG centrally controls the restraint system (SRS) in Dodge. It evaluates the crash sensors and, in the event of an accident, determines within milliseconds which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

During operation the control unit checks the entire system continuously. If it detects a fault, the airbag warning light in the instrument cluster appears.

The crash data document the event from the unit's point of view. They are stored in the control unit itself.

Why does the control unit 68085880AG fail?

Crash data stored in the unit after an accident are the most common cause for control unit 68085880AG, even if no airbag has deployed. Further possible causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

A normal diagnostic tool cannot erase this data. Airbag24 takes care of the erasure as part of the repair.

Aged components and cold solder joints cannot be seen from outside; here the hints from the fault memory provide information. Moisture and corrosion disturb plug connections, and voltage spikes, for example from a weak battery or from jump-starting, stress the electronics.

How can you tell that the 68085880AG is defective?

A defect in the 68085880AG becomes visible through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared also point to it.

The diagnostic tool is then unable to address the control unit. In an emergency, airbags and seatbelt pretensioners may not be able to deploy, so the check should not wait.
