Airbag control unit with part number 68346758AB

What does the airbag control unit 68346758AB do?

The 68346758AB is the airbag control unit of the SRS system in Dodge. It evaluates the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

The unit monitors the entire system continuously and reports faults to the airbag warning light in the instrument cluster.

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

Why does the control unit 68346758AB fail?

The most common cause for the 68346758AB is crash data stored after an accident, even without a triggered airbag. Other causes are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair.

The other causes are aged electronics, poor contacts at connectors, and voltage spikes, for example from a weak battery or a jump start.

How can you tell that the 68346758AB is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as the 68346758AB has a defect. In addition a fault message appears, the diagnostic tool receives no connection, and the fault memory remains.

This light is a clear signal, because the system has detected a fault in the restraint system.

In an emergency, airbags and seatbelt pretensioners may not deploy. Therefore take the warning seriously and have the fault checked.
