Airbag control unit with part number 68367618AA

What does the airbag control unit 68367618AA do?

The airbag control unit 68367618AA is the central control unit of the restraint system (SRS) for Dodge and Jeep. It analyses the signals from the crash sensors, decides within milliseconds in the event of an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows any faults it finds via the airbag warning light.

The crash sensors constantly supply measured values to the unit. In addition, it checks the wiring to the airbags and seatbelt pretensioners, so that the system is fully ready for use in an emergency.

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

Why does the control unit 68367618AA fail?

Stored crash data is the most common cause, even if no airbag has triggered. Other possible causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data remains stored because a normal diagnostic tool cannot delete it. Airbag24 erases it during repair.

The other causes concern the unit itself or its connections:

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

How can you tell that the 68367618AA is defective?

The airbag warning light in the instrument cluster stays on constantly or intermittently, and an error message appears in the instrument cluster. In addition there is no connection to the diagnostic tool, and the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may possibly not trigger in an emergency.

These signs show you the defect as soon as the control unit detects it. If any of them appears, have the system checked promptly.

Only reading the fault memory will show whether the control unit itself is affected.
