Airbag control unit with part number 68346721AA

What does the airbag control unit 68346721AA do?

As the control unit of the restraint system (SRS) of Dodge, the airbag control unit 68346721AA evaluates the crash sensors. In an accident it decides within milliseconds on airbags and seatbelt pretensioners and monitors the system continuously.

It indicates faults via the airbag warning light. After an accident the unit stores crash data and locks itself.

Why does the control unit 68346721AA fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. Other causes include aged components, cold solder joints, moisture and corrosion, and voltage spikes.

A normal diagnostic tool cannot delete crash data. Airbag24 deletes it during the repair.

Aged electronics, cold solder joints and corrosion at plug connections develop gradually and show over a longer period.

Voltage spikes, for example from a weak battery or when jump-starting, place additional strain on the circuits.

How can you tell that the 68346721AA is defective?

A defect shows up as the airbag warning light in the instrument cluster staying on permanently or intermittently. The control unit then cannot be reached with the diagnostic tool.

• Airbag warning light stays on permanently or intermittently
• Fault message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may therefore not trigger. Have such a warning sign checked promptly.
