Airbag control unit with part number 68085881AI

What does the airbag control unit 68085881AI do?

The unit 68085881AI is the airbag control unit for Dodge and forms the centre of the restraint system (SRS). It processes the signals from the crash sensors and triggers the matching airbags and seatbelt pretensioners within milliseconds in an accident.

In addition, it monitors the system constantly and reports faults via the airbag warning light.

After an accident the control unit stores crash data and locks itself.

Why does the control unit 68085881AI fail?

Stored crash data from an accident is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Other causes: aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The fault memory shows which cause applies to the individual unit. Reading out this memory is therefore the first step of every diagnosis.

Ageing and moisture affect the contacts over time. Voltage spikes arise, for example, with a weak battery or when starting with a jump start.

How can you tell that the 68085881AI is defective?

A defect shows itself through the airbag warning light in the instrument cluster, which is lit permanently or intermittently. In addition there are fault messages in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

If the warning light is on, the restraint system is not in order. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The cause can lie in the control unit itself or in a cable or plug; only the readout shows which one it is.
