Airbag control unit with part number 68346712AB

What does the airbag control unit 68346712AB do?

The airbag control unit 68346712AB is the central computing unit of the restraint system in Dodge vehicles. It evaluates the acceleration signals, decides within fractions of a second in an accident which airbags and seatbelt pretensioners are triggered, and monitors the entire system. If it detects a fault, it indicates it via the airbag warning light.

After an accident, the unit stores crash data and locks itself. The sensors and the control unit together form the chain that must work in an emergency.

Why does the control unit 68346712AB fail?

The most common cause with the 68346712AB is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes include ageing electronics, cold solder joints, moisture at plug connections, and voltage spikes.

The fault therefore need not lie in the component itself, but can be based on the stored content. Airbag24 erases the crash data during the repair.

Electronic components age over time, solder joints can go cold or break, and moisture affects the contacts. Voltage spikes, for example from a weak battery or from jump-starting, also stress the electronics.

How can you tell that the 68346712AB is defective?

A defect on the 68346712AB becomes recognisable through the airbag warning light in the instrument cluster, which lights up constantly or intermittently. The diagnostic tool then also finds no connection to the control unit, and the fault memory cannot be cleared.

While such a fault exists, airbags and seatbelt pretensioners may not deploy in an emergency. The signs at a glance:

• airbag warning light on, constantly or intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared
