Airbag control unit with part number P56054623AD

What does the airbag control unit P56054623AD do?

The airbag control unit P56054623AD coordinates the restraint system (SRS) in Dodge. It receives the signals from the crash sensors, decides within fractions of a second during an accident which airbags and seatbelt pretensioners to trigger, and monitors the system during operation. It shows faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. The control unit thereby responds to events that occur while driving.

Sensors, wiring harnesses and airbags form an overall system together with the control unit. Its function depends on all parts working together reliably.

Why does the control unit P56054623AD fail?

Stored crash data is the most common cause, and this also applies if no airbag was deployed in the accident. They cannot be removed with a normal diagnostic tool. In addition there are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as from a weak battery or a jump start.

The data is created in the unit when it evaluates the accident, and remains stored there.

Aged electronics, cold solder joints and moisture at plugs are also among the causes. Voltage spikes from a weak battery or a jump start come on top of that.

How can you tell that the P56054623AD is defective?

An airbag warning light that stays on permanently or lights up from time to time in the instrument cluster is a clear sign. In addition a fault message may appear, the diagnostic tool cannot find the control unit, and the fault memory remains.

In an emergency, airbags and seatbelt pretensioners may fail to deploy in the event of a defect.

The warning light indicates the defect, and therefore every message is a reason to have the unit checked.

First compare the part number on the label of the removed unit with this page; then you know that it is the correct unit. Have the fault memory read out beforehand, because only that shows whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 0285015046, 56043128AC, 56043128AD, 68303217AA, 68303218AA, 68346712AA.

How does the repair of the P56054623AD work?

First have the fault memory read out and enclose the log with the unit. Then disconnect the battery and only afterwards remove the control unit. Create the repair order online and send in the well-packed unit; at Airbag24, checking, repairing and testing usually take 3–4 working days.

Airbag24 checks the unit on the test bench, replaces defective components and erases stored crash data. A function test follows at the end, after which your own unit is returned.

The order is binding, because disconnecting the battery and removing the unit may only be done after the readout.

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 P56054623AD get to Airbag24?

To get to Airbag24, you either send the unit as a parcel or have it collected by UPS for an extra charge. The return after the repair is likewise by UPS.

Put the printed repair order into the parcel and secure the unit shock-resistant.
