Airbag control unit with part number 68346712AC

What does the airbag control unit 68346712AC do?

The 68346712AC is the central control unit of the SRS restraint system in Dodge vehicles. It evaluates the crash sensors and, in a crash, decides within milliseconds which airbags and seatbelt pretensioners are triggered.

In operation it monitors all functions of the system. It reports faults via the airbag warning light in the instrument cluster.

After an accident the unit records crash data and is locked afterwards.

Why does the control unit 68346712AC fail?

The most common cause is crash data stored after an accident on the 68346712AC, even if no airbag was triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

Crash data cannot be erased with a standard diagnostic tool. It is erased during the repair by Airbag24.

Aged electronic components and cold solder joints also lead to failures. Moisture, corrosion and voltage spikes, for example from a weak battery or a jump start, additionally stress the plug connections.

How can you tell that the 68346712AC is defective?

A defect on the 68346712AC becomes visible when the airbag warning light in the instrument cluster stays on permanently or intermittently. In addition, fault messages occur, the diagnostic tool cannot reach the control unit, and the fault memory cannot be cleared.

While such signs are present, airbags and seatbelt pretensioners may not trigger in an emergency. Only the fault memory you have read out confirms whether the control unit itself is affected.
