Airbag control unit with part number 68085882AF

What does the airbag control unit 68085882AF do?

The 68085882AF is the central control unit of the restraint system for Dodge. It checks the signals from the crash sensors, decides in a crash which airbags and seatbelt pretensioners are triggered, and monitors the entire system. After an accident it stores crash data and locks itself.

The evaluation runs in the background throughout the journey. If a fault enters the system, the unit reports it via the airbag warning light.

Why does the control unit 68085882AF fail?

The most common cause with the 68085882AF is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Other causes are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

The crash data stay stored in the unit until they are erased. The fact that no airbag triggered in the incident does not cancel the storage.

Electronic components age over time, and cold solder joints can cause contact problems. Moisture and corrosion at the plug connectors work in the same direction.

Voltage spikes also strain the electronics, for example with a weak battery or when jump starting.

How can you tell that the 68085882AF is defective?

A defect shows up as the airbag warning light, which lights up permanently or intermittently, as a fault message in the instrument cluster, and as a fault memory that cannot be cleared. In addition, the diagnostic tool cannot establish a connection to the 68085882AF. In these cases the airbags and seatbelt pretensioners may not trigger in an emergency.

• airbag warning light in the instrument cluster, permanently or intermittently
• fault message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be cleared

The warning light is the most direct indication. Anyone who ignores it is driving with a restraint system whose function is not assured.
