Airbag control unit with part number 68222269AC

What does the airbag control unit 68222269AC do?

The airbag control unit 68222269AC is the central control unit of the restraint system (SRS) for Dodge. It evaluates the signals from the crash sensors, decides in a crash within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

If the unit detects a fault, it reports it via the airbag warning light. The evaluation runs in the background throughout the entire journey.

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

Why does the control unit 68222269AC fail?

The most common cause on the 68222269AC is crash data stored after an accident, even if no airbag has triggered; a normal diagnostic tool cannot erase it. Other causes in brief:

• aged electronic components
• cold solder joints
• moisture and corrosion at connectors
• voltage spikes, for example from a weak battery or jump-starting

The crash data remains in the memory until it is removed during the repair. Reading it out with a diagnostic tool displays it but does not remove it.

The remaining causes concern the electronics themselves and develop over a longer period. Moisture and corrosion mainly disturb the signal transmission at the connectors.

How can you tell that the 68222269AC is defective?

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

These signs appear with a defect on the 68222269AC, and the warning light shows it as soon as the unit detects it. It is worth keeping an eye on the light before the fault grows.

As long as the defect persists, airbags and seatbelt pretensioners may possibly not trigger in an emergency. Please have the fault checked promptly.
