Airbag control unit with part number P04672501AF

What does the airbag control unit P04672501AF do?

The airbag control unit P04672501AF is the central control unit of the restraint system (SRS) for Dodge. It evaluates the signals from the crash sensors, decides in an accident within milliseconds about triggering airbags and seatbelt pretensioners, and monitors the system continuously.

The unit shows faults via the airbag warning light in the instrument cluster. The light is therefore the interface between the control unit and the driver.

After an accident, it stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit P04672501AF fail?

The most common cause is crash data stored after an accident, even without a triggered airbag. A normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 removes the crash data during the repair. Until then, it stays stored in the control unit.

The remaining causes concern electronics and connections. Aged components and cold solder joints appear over time, while moisture and corrosion attack plug connections.

How can you tell that the P04672501AF is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition, there is a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

As long as the light shows a fault, airbags and seatbelt pretensioners may not trigger in an emergency. You should therefore look into a lit warning light promptly.

A single sign does not reveal the cause. Reading out the fault memory shows whether the control unit is affected.
