Airbag control unit with part number 68297877AA

What does the airbag control unit 68297877AA do?

The airbag control unit 68297877AA is the central control unit of the restraint system for Dodge. It evaluates the signals from the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the system constantly.

The unit reports faults via the airbag warning light in the instrument cluster. The monitoring covers all connected components of the system.

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

Why does the control unit 68297877AA fail?

The most common cause in the control unit 68297877AA is crash data stored after an accident, even if no airbag was triggered. Aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes can also cause the failure.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases it during the repair, so the unit can then be checked without this lock.

Aged electronic components can show up only under certain conditions. Moisture and corrosion attack the contacts, and voltage spikes arise, for example, with a weak battery or jump-starting.

How can you tell that the 68297877AA is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool cannot connect to the control unit 68297877AA, and the fault memory cannot be cleared.

In an emergency, the airbags and seatbelt pretensioners may then fail to trigger. If the warning light is on, have the system checked promptly.

Only reading out the fault memory reveals the cause.
