Airbag control unit with part number 68263743AA

What does the airbag control unit 68263743AA do?

The airbag control unit 68263743AA is the central control unit of the restraint system (SRS) for Dodge. It evaluates the signals from the crash sensors, decides in an accident within the shortest possible time which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. If it detects a fault, it indicates this via the airbag warning light.

During operation the unit checks all connected components continuously. If it finds a deviation, it stores it in the fault memory.

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

Why does the control unit 68263743AA fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot delete them. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start. Airbag24 deletes the crash data during the repair.

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

Crash data are created even after accidents in which no airbag deploys, and they remain in the memory until they are deleted. A normal diagnostic tool cannot remove them.

The other causes lie in the electronics themselves and show up only intermittently.

How can you tell that the 68263743AA is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears. In addition, the diagnostic tool does not establish a connection to the control unit, or the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light is the most important warning sign of the system. It indicates a detected fault even when nothing unusual is noticeable while driving, which is why you should take it seriously.

If the light comes on only intermittently, still have the fault memory read out, because the entry remains stored even then.

How does the repair of the 68263743AA work?

You first have the fault memory read out and attach the log. Then you disconnect the battery, remove the control unit, create a repair order online and send the unit in well packed. Processing at Airbag24 usually takes 3–4 working days; during this time Airbag24 inspects the unit on the test bench, repairs defective components, deletes stored crash data and carries out a function test.

The sequence is binding for safety reasons. The control unit may be removed only after the battery has been disconnected.

After the function test, Airbag24 sends your own unit back to you. The stated time covers only the work at Airbag24 and includes neither your steps nor the shipping.
