Airbag control unit with part number 68358991AC

What does the airbag control unit 68358991AC do?

The airbag control unit 68358991AC is the central control unit of the restraint system (SRS) for Chrysler. It evaluates the signals from the crash sensors and, in the event of an accident, determines within milliseconds which airbags and seatbelt pretensioners are triggered.

The control unit monitors the system continuously. It shows detected faults via the airbag warning light in the instrument cluster.

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

Why does the control unit 68358991AC fail?

Stored crash data is the most common cause with the 68358991AC, even if no airbag has deployed. Other causes are aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

After an accident, stored crash data remains in the unit. A normal diagnostic tool cannot delete it; Airbag24 deletes it during the repair.

Ageing of the electronics, cold solder joints and moisture at plug connections are among the other causes. Voltage spikes are also possible, for example when the battery is weak or a jump start is carried out.

How can you tell that the 68358991AC is defective?

The airbag warning light in the instrument cluster indicates a fault in the 68358991AC when it lights up permanently or intermittently. In addition, an error message appears in the instrument cluster, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

The display in the instrument cluster is therefore the most important sign for you. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Please respond to this display promptly.
