Airbag control unit with part number 68405567AB

What does the airbag control unit 68405567AB do?

The airbag control unit 68405567AB is the central control unit of the restraint system (SRS) in Chrysler. It evaluates the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. It shows faults via the airbag warning light.

The unit works along while driving and checks the components continuously. If it notices an irregularity, it records the finding in the fault memory.

After an accident it stores crash data and locks itself. The lock is lifted only by the repair.

Why does the control unit 68405567AB fail?

The most common cause is crash data stored after an accident, even if no airbag went off; a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data remains stored in the unit after an accident, even if the vehicle continues to drive without any problems. The other causes mainly concern wear and moisture on contacts. Voltage spikes arise, for example, from a weak battery or a jump start.

Airbag24 erases the crash data during the repair. Which other cause is present is determined by the check.

How can you tell that the 68405567AB is defective?

A fault shows itself through an airbag warning light in the instrument cluster that lights up permanently or intermittently, an error message in the instrument cluster, a diagnostic tool without connection to the control unit, or a fault memory that cannot be cleared. In these cases the airbags and seatbelt pretensioners may not trigger in an emergency.

These signs are a clear indication that the restraint system must be checked. Have it examined promptly.
