Airbag control unit with part number 68409681AA

What does the airbag control unit 68409681AA do?

The airbag control unit 68409681AA controls the restraint system (SRS) for Jeep. It evaluates the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates faults via the airbag warning light. After an accident it stores crash data and locks itself.

The measurements of the crash sensors flow into the control unit continuously. The evaluation is designed to decide in time in an emergency.

A glance at the instrument cluster is enough to see the state of the system. The monitoring works regardless of whether you do anything for it.

Why does the control unit 68409681AA fail?

The most common cause with this unit is stored crash data after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Other causes, in brief:

• ageing electronic components,
• cold solder joints,
• moisture and corrosion at plug connections,
• voltage spikes, for example from a weak battery or a jump start.

The control unit stores the crash data after the accident. During the repair at Airbag24 they are deleted.

How can you tell that the 68409681AA is defective?

A defect on the 68409681AA shows when the airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears, the diagnostic tool cannot make a connection, or the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The airbag warning light reports the defect directly in your field of view. You can therefore recognise it from the indicator itself.

If you see the light, have the system checked promptly. A lack of contact with the diagnostic tool is also one of the signs.
