Airbag control unit with part number 68346751AA

What does the airbag control unit 68346751AA do?

The airbag control unit 68346751AA coordinates the restraint system (SRS) for Dodge. It continuously checks the crash sensors, calculates within milliseconds in an accident which airbags and seatbelt pretensioners trigger, and monitors itself. After an accident it stores crash data and locks itself.

Faults are shown via the airbag warning light in the instrument cluster.

The crash data record what happened in the accident.

Why does the control unit 68346751AA fail?

It most often fails because of stored crash data arising after an accident, even if no airbag triggered; ordinary diagnostic tools cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Stored crash data is the most common cause, because the unit stores it even when no airbag triggers.

Other influences are also possible:

• aged 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 68346751AA is defective?

The airbag warning light in the instrument cluster lights up permanently or flickers at times, which is a warning signal. In addition there is a fault message in the instrument cluster, no connection of the diagnostic tool to the 68346751AA, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

It is precisely the warning light that catches the eye first in everyday use, and it belongs to the warning system of the vehicle.

If the diagnostic tool also fails to connect, that is a further sign of a fault in the system.
