Airbag control unit with part number 68085880AF

What does the airbag control unit 68085880AF do?

68085880AF is the airbag control unit in the restraint system (SRS) of Dodge. From the signals of the crash sensors, it calculates whether and which airbags and seatbelt pretensioners trigger in a crash, and monitors the system continuously. Any faults that occur are shown via the airbag warning light.

The decision is made within milliseconds, which is why the electronics work constantly in the background.

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

Why does the control unit 68085880AF fail?

The most frequent trigger for a failure is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Further causes are aging of components, cold solder joints, moisture, corrosion and voltage spikes.

Crash data records what happened in the accident. Airbag24 erases it during the repair.

Aging, cold solder joints and corrosion at plug connections are hardly noticeable from outside until they cause faults.

Voltage spikes arise, for example, from a weak battery or when starting with a jump start.

How can you tell that the 68085880AF is defective?

The airbag warning light in the instrument cluster, which lights up permanently or intermittently, is the first sign of a defect. Also present are fault messages in the instrument cluster, a diagnostic tool without connection to the control unit and a fault memory that cannot be cleared; in an emergency, airbags and seatbelt pretensioners may then not deploy.

That the light shows the fault is the actual purpose of this warning.

If you see such an indication, take it seriously and have the system checked.

Comparing the part number on the label of the removed unit with this page only confirms that it is the right unit. Beforehand, have the fault memory read out, because this log alone 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 0285015046, 56043128AC, 56043128AD, 68303217AA, 68303218AA, 68346712AA.

How does the repair of the 68085880AF work?

You first read out the fault memory, enclose the log and then disconnect the battery before removing the control unit. Online you create the repair order, and you send the well-packed unit in. Airbag24 tests it, replaces defective components, erases the crash data and performs a function test, after which your own unit goes back to you.

Reading out beforehand is the basis for the check later.

For the work at Airbag24, i.e. testing, repairing and function testing, 3–4 working days are usually scheduled.

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.
