Airbag control unit with part number 68227450AC

What does the airbag control unit 68227450AC do?

The airbag control unit 68227450AC controls the restraint system in Chrysler vehicles. It evaluates the signals from the crash sensors and, in a crash, decides within fractions of a second which airbags and seatbelt pretensioners are triggered.

At the same time, it checks the system continuously. Faults are indicated via the airbag warning light in the instrument cluster.

After a crash, it stores crash data and locks itself. The protective effect of the vehicle therefore depends on this unit.

Why does the control unit 68227450AC fail?

Crash data stored after an accident is the most common cause in the 68227450AC, even if no airbag has deployed. A standard diagnostic tool cannot erase this data. Other possible causes include ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 removes the crash data during the repair, even though a standard diagnostic tool cannot erase it.

The other causes develop over time. Moisture attacks contacts, solder joints lose their strength, and voltage spikes stress the electronics.

How can you tell that the 68227450AC is defective?

The airbag warning light in the instrument cluster lights up on the 68227450AC permanently or intermittently. An error message may be added, and the diagnostic tool receives no connection to the control unit. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The signs in detail:

• Airbag warning light on permanently or intermittently.
• Error message in the instrument cluster.
• Diagnostic tool without connection to the control unit.
• Fault memory cannot be cleared.

If you see the warning light, have the fault memory read out promptly.
