Airbag control unit with part number 68444299AC

What does the airbag control unit 68444299AC do?

The airbag control unit 68444299AC is the central control unit of the SRS restraint system for Chrysler. It reads the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows faults via the airbag warning light.

The unit works in the background and does not intervene during normal operation. Its task is to be able to make a reliable decision at any time.

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

Why does the control unit 68444299AC fail?

Crash data stored in the unit after an accident is most often the cause, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Other causes are:

• 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 is the most frequent cause because it remains in the memory after the accident. The other causes concern the electronics and the contacts, and they develop over the service life of the vehicle.

How can you tell that the 68444299AC is defective?

The airbag warning light in the instrument cluster lights up permanently or comes on intermittently. In addition, there is a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

If these signs are present, airbags and seatbelt pretensioners may not trigger in an emergency. A check is therefore advisable as soon as the warning light comes on.

No connection to the diagnostic tool does not necessarily mean damage to the control unit. The wiring may also be affected, and the check shows what the cause is.
