Airbag control unit with part number 68316737AA

What does the airbag control unit 68316737AA do?

The airbag control unit 68316737AA is the central unit of the SRS for Dodge vehicles. It captures the signals from the crash sensors, selects in an accident, within milliseconds, the airbags and seatbelt pretensioners that should deploy, and monitors the system continuously. After an accident it stores crash data and locks itself.

If the monitoring detects a fault, it is shown by the airbag warning light in the instrument cluster. The lock only ends with a repair.

Why does the control unit 68316737AA fail?

Stored crash data after an accident is the most common cause of the 68316737AA failing, even if no airbag was deployed. An ordinary diagnostic tool cannot remove it. Other causes include aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or a jump start.

Airbag24 erases the crash data during the repair, so that it is no longer in memory once the unit is returned.

The other causes concern the electronics and their connections. Solder joints that have gone cold, and contacts attacked by moisture, can disturb the unit during operation.

How can you tell that the 68316737AA is defective?

A defect on the 68316737AA is shown mainly by the airbag warning light in the instrument cluster, which can stay on permanently or come on intermittently. Fault messages may also appear in the instrument cluster, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be erased.

If a defect occurs, airbags and seatbelt pretensioners may not deploy in an emergency. A warning of this kind must therefore be taken seriously.
