Airbag control unit with part number 68085880AD

What does the airbag control unit 68085880AD do?

The airbag control unit 68085880AD is responsible for the restraint system (SRS) of Dodge. It evaluates impact signals, determines within milliseconds which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. It reports faults via the airbag warning light.

The evaluation follows defined criteria, which the control unit re-assesses for every event.

If there has been an accident, the unit stores crash data and locks itself.

Why does the control unit 68085880AD fail?

The most common cause on the 68085880AD is crash data from an accident, even if no airbag was deployed; a standard diagnostic tool cannot erase it. Further causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data is created regardless of whether airbags have been deployed. The unit stores it in the background, without any need for triggering.

Aged electronics and cold solder joints can cause faults that only appear under certain loads.

Moisture and corrosion at plug connections disturb the contact. Voltage spikes, for example from a weak battery or jump-starting, stress the circuit inside the unit.

How can you tell that the 68085880AD is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently as soon as there is a fault on the 68085880AD. In addition, an error message appears, the diagnostic tool cannot reach the control unit, and the fault memory cannot be cleared. In that case airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light is the direct sign that the system has detected a fault. Treat it as a serious warning.

If it stays on permanently, have the system checked promptly.
