Airbag control unit with part number 68085883AE

What does the airbag control unit 68085883AE do?

The airbag control unit 68085883AE is the central control unit of the restraint system (SRS) of Dodge. It evaluates the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

The crash sensors deliver their measurements to the control unit continuously. Its evaluation is designed so that the decision is made in time in an emergency.

Faults are reported by the control unit via the airbag warning light in the instrument cluster.

Why does the control unit 68085883AE fail?

On the 68085883AE the most common cause is stored crash data after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start.

The control unit stores the crash data after the accident and locks itself. During the repair at Airbag24, stored crash data is deleted.

Ageing electronics and cold solder joints impair the function over a longer period. Moisture and corrosion at the plugs disturb the contact, and voltage spikes additionally strain the components.

How can you tell that the 68085883AE is defective?

A defect on the 68085883AE shows through the airbag warning light, which stays on permanently or intermittently, an error message, no connection to the diagnostic tool, or a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light shows the defect directly. An error message in the instrument cluster supplements this display.

If you notice one of these signs, have the system checked promptly.
