Airbag control unit with part number 68105510AB

What does the airbag control unit 68105510AB do?

The airbag control unit 68105510AB manages the restraint system (SRS) in the Chrysler. It evaluates the crash sensors, decides within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Evaluating the sensor signals is the core of its task. Without them, the system would not know which elements are needed in an accident.

If a fault occurs, the airbag warning light in the instrument cluster lights up. After an accident the unit stores crash data and locks itself.

Why does the control unit 68105510AB fail?

Stored crash data is the most common cause with the 68105510AB, even if no airbag has triggered; further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase the crash data. Airbag24 removes it during the repair.

Other causes relate to the electronics in general: components age, solder joints can go cold, and moisture and corrosion damage plug connections.

Voltage spikes, for example from a weak battery or a jump start, can also contribute to a failure.

How can you tell that the 68105510AB is defective?

A defect in the 68105510AB shows up as the airbag warning light in the instrument cluster lighting up constantly or intermittently, as an error message, as a missing connection to the diagnostic tool and as a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then not trigger. The finding should therefore be checked promptly.
