Airbag control unit with part number P04672505AF

What does the airbag control unit P04672505AF do?

The airbag control unit P04672505AF coordinates the SRS restraint system in Dodge. It reads the crash sensors, determines in an emergency within milliseconds the triggering of airbags and seatbelt pretensioners, and checks the system continuously. It indicates faults via the airbag warning light.

The sensors supply values to the unit continuously. Triggering takes place only when the evaluation confirms an impact.

After an accident, the unit stores crash data and locks itself. The memory records the event whether or not an airbag actually ignited.

Why does the control unit P04672505AF fail?

Crash data stored after an accident are regarded as the most common cause, even without a triggered airbag. A normal diagnostic tool cannot clear them. Aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are added to this.

Crash data remain in the unit while the vehicle can drive quite normally. The unit keeps the entry until Airbag24 removes it during the repair.

The other causes also include connections in the vehicle that loosen over time. A weak battery or a jump-start can produce voltage spikes that strain the unit.

How can you tell that the P04672505AF is defective?

A defect in the P04672505AF can be recognised by the airbag warning light in the instrument cluster. It lights up permanently or intermittently, and in an emergency airbags and seatbelt pretensioners may possibly fail to deploy.

The following signs may accompany it:

• error message in the instrument cluster
• diagnostic tool without connection to the control unit
• fault memory that cannot be cleared

The light alone is enough reason to have the system checked.

For the same vehicles, we also repair control units with the part numbers 4672602AB, 4896616AA, 4896616AB, 68148034AA, P04672603AE, P04896621AE.

How does the repair of the P04672505AF work?

You read out the fault memory and attach the log to the unit. Then disconnect the battery before you remove the P04672505AF. After that, create the repair order online and send the unit in well packed.

Airbag24 examines the unit, repairs the affected components, removes the stored crash data and carries out a function test. Your own unit then comes back to you. Airbag24 generally allows 3–4 working days for this.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
