Airbag control unit with part number P68148050AA

What does the airbag control unit P68148050AA do?

The airbag control unit P68148050AA is the central unit within the restraint system (SRS) for Dodge. It analyses the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners trigger, and checks the entire system continuously.

A fault is displayed via the airbag warning light in the instrument cluster. The sensors supply data, but the verdict is reached in the control unit.

After an accident, it stores crash data and locks itself. How this comes about and how a failure is noticed is described in the sections that follow.

Why does the control unit P68148050AA fail?

Crash data stored after an accident most often causes problems on the P68148050AA, regardless of whether an airbag has fired. Other causes include component ageing, cold solder joints, moisture together with corrosion, and voltage spikes.

A normal diagnostic tool cannot delete this crash data. That only happens during the repair at Airbag24.

Component ageing and cold solder joints impair function without any prior accident. Moisture and corrosion worsen the contact at plug connections.

Voltage spikes, for example from a weak battery or jump-starting, act on the electronics and can promote faults.

How can you tell that the P68148050AA is defective?

The airbag warning light in the instrument cluster lights up on the P68148050AA permanently or intermittently. Fault messages, a missing connection to the diagnostic tool and a fault memory that cannot be cleared come on top of this.

The light shows that the system has detected a fault. As long as this is the case, the airbags and seatbelt pretensioners may not trigger in an emergency.

A missing connection to the diagnostic tool does not necessarily lie in the control unit alone. Wiring and connectors are also possible causes, and the read-out of the fault memory decides.

Which vehicles is the P68148050AA fitted in?

The control unit P68148050AA is fitted in these vehicles: Dodge Avenger Saloon (2007-2011) and Saloon Facelift (2011-2014).

The following list names the vehicles stored for this part number.

• Dodge Avenger Saloon (2007-2011)
• Dodge Avenger Saloon Facelift (2011-2014)

Comparing the part number on the label of the removed unit with this page only confirms the identity of the unit. Having the fault memory read out beforehand, on the other hand, shows whether the control unit is defective or whether a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 56054100AA, 56054100AB, 56054100AC, 56054100AD, 68029112AA, 68029112AB.

How does the repair of the P68148050AA work?

You read out the fault memory of the P68148050AA first, enclose the log and then disconnect the battery. Next, remove the control unit, create the repair order online and send the unit in packaged. At Airbag24, processing usually takes 3–4 working days.

The sequence protects you when working on the airbag system and is therefore binding.

At Airbag24 the unit is checked on the test bench, defective components are repaired, stored crash data is deleted and a functional test follows. After that, your own unit 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 P68148050AA get to Airbag24?

You send the control unit P68148050AA as a parcel or, for an extra charge, book a UPS collection. After the repair, the unit is returned to you by UPS.

Place the printed repair order in the parcel and pack the unit shock-proof.
