Airbag control unit with part number 68085880AE

What does the airbag control unit 68085880AE do?

For Dodge, the airbag control unit 68085880AE is the central control unit of the SRS restraint system. It processes the signals from the crash sensors, decides in an accident whether airbags and seatbelt pretensioners fire, and monitors the system continuously.

Faults are reported via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.

As long as everything is in order, the monitoring runs unobtrusively in the background.

Why does the control unit 68085880AE fail?

On the 68085880AE, the most common cause is storage of crash data from an accident, even without a triggered airbag; an ordinary diagnostic tool does not erase it. Other causes are aged electronic components, cold solder joints, moisture or salt on plug connections, and voltage spikes.

Storage takes place even when no airbag fires.

Electronics age, solder joints become prone to faults over time, and moisture or salt attack plug connections. Voltage spikes, for example when starting with a weak battery or when jump-starting, can also damage the unit.

How can you tell that the 68085880AE is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. At the same time an error message appears, and a diagnostic tool cannot establish a connection to control unit 68085880AE. The fault memory also cannot be cleared, and as a result airbags and seatbelt pretensioners may fail to deploy in an emergency.

That the light shows the defect is its actual purpose.

If the light is on, a prompt check is the right step.
