Airbag control unit with part number 56054911AD

What does the airbag control unit 56054911AD do?

The airbag control unit 56054911AD controls the restraint system (SRS) in Dodge vehicles. It evaluates the signals from the crash sensors, decides within milliseconds in a crash whether airbags are triggered and seatbelt pretensioners fire, and monitors the entire system continuously. Faults are reported via the airbag warning light.

The electronics are designed precisely for these processes. They work in the background until an emergency occurs, and then react without delay.

After a crash, the control unit stores crash data and locks itself.

Why does the control unit 56054911AD fail?

The most common cause is crash data stored after an accident, even without airbags being triggered. A normal diagnostic tool cannot erase this data. Other causes are aged components, cold solder joints, moisture and corrosion at plugs, and voltage spikes, for example from a weak battery or a jump start.

An impact in which no airbag was triggered can still leave crash data in the memory. It remains there until it is removed by a special procedure.

Age-related changes to components and cold solder joints on the circuit board lead to faults that cannot always be reproduced. Moisture and corrosion at the plug connections have a similar effect.

Voltage spikes from the vehicle electrical system are a further factor. A check of the battery and plugs is therefore part of the fault search.

How can you tell that the 56054911AD is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. In addition there is no connection between the diagnostic tool and the control unit, and the fault memory cannot be cleared. In this state, airbags and seatbelt pretensioners may possibly not trigger in an emergency.

The warning light is the clearest sign. It shows that the system has detected a fault and stays active until the cause is clarified.

A fault message in the instrument cluster confirms the finding. If the diagnostic tool cannot be connected, that is another sign of a fault.

Which vehicles is the 56054911AD fitted in?

The control unit 56054911AD is fitted in these vehicles: Dodge Journey 1st generation (2008-2010) and 1st generation Facelift (2010-2020). The list below shows the individual vehicles.

Here is the assignment:

• Dodge Journey 1st generation (2008-2010)
• Dodge Journey 1st generation Facelift (2010-2020)

Comparing the part number on the label of the removed unit with this page only secures that it is the right unit. Only the fault memory, read out, shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 4896814AH, 56054655AD, 56054655AE, 56054711AD, 56054733AF, 56054744AE.

How does the repair of the 56054911AD work?

First have the fault memory read out and attach the log. Then disconnect the battery and only then remove the control unit. Next, create a repair order online and send the unit in well packed. Airbag24 usually processes it within 3–4 working days.

The sequence is binding for safety reasons. Removal follows only once the fault memory and the battery have been dealt with.

Airbag24 checks the control unit on the test bench and replaces defective components. Stored crash data is erased, and a function test follows. Your own unit then goes back to you.

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.

How does the control unit 56054911AD get to Airbag24?

You send the unit in as a parcel, or you book a UPS collection for an extra charge. After the repair, Airbag24 sends the unit back to you by UPS.

Put the printed repair order in the parcel. The control unit is packed shock-proof.
