Airbag control unit with part number 68233535AC

What does the airbag control unit 68233535AC do?

The airbag control unit 68233535AC controls the restraint system (SRS) in Chrysler and Dodge. It constantly checks the signals from the crash sensors and, in a crash, decides within a fraction of a second which airbags and seatbelt pretensioners to deploy.

During operation, it monitors the system and reports faults via the airbag warning light in the instrument cluster.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 68233535AC fail?

Most often the cause lies in crash data stored after an accident, even if no airbag has deployed. A standard diagnostic tool cannot erase it. Aged electronics, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes come on top of this.

Crash data remains in the unit as stored content until it is removed in a targeted way.

Ageing of the electronics affects components and solder joints that have been exposed to temperature changes over years.

Moisture and corrosion at plug contacts, as well as voltage spikes, for example from a weak battery or a jump start, put additional strain on the unit.

How can you tell that the 68233535AC is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

The defect is therefore visible above all in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may fail to deploy. Have the warning checked promptly.
