Airbag control unit with part number 68211617AD

What does the airbag control unit 68211617AD do?

The airbag control unit 68211617AD is the central control unit of the restraint system (SRS) for Chrysler. It evaluates the signals from the crash sensors and decides in an accident, within fractions of a second, which airbags and seatbelt pretensioners to trigger.

While driving, the device monitors the entire system continuously. If it detects a fault, it reports it via the airbag warning light in the instrument cluster, so that the problem is not overlooked.

After an accident the control unit stores crash data and locks itself. Whether and when a fault occurs depends on how the overall system interacts, which is why you should always consider the system as a whole.

Why does the control unit 68211617AD fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A standard diagnostic tool cannot erase it, and Airbag24 deletes it during the repair. Other causes are aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes, for example from a weak battery or a jump start.

The stored data remains in the device even if nothing was triggered during the event. A standard diagnostic tool therefore does not help in this case.

The other causes develop gradually. Electronic components age, solder joints lose their firm hold over time, and moisture attacks plug connections. Voltage spikes occur, for example, when the battery is weakening or the vehicle is started with external power.

How can you tell that the 68211617AD is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

If the warning light stays on after the ignition is switched on, does not go out again or flickers while driving, there is a fault in the restraint system. A diagnostic tool that cannot establish a connection is also an indication of this.

Have the finding checked promptly rather than ignoring the display for a long time. Only then will you learn whether the control unit itself is affected.

(a) Compare the part number on the label of the removed unit with this page; that only confirms it is the correct unit. (b) Have the fault memory read out beforehand, because only that shows whether the control unit is defective or whether a connector or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 68405565AB, 68405565AC, 68405567AC, 68405937AA, 68405939AA, 68480707AC.

How does the repair of the 68211617AD work?

First have the fault memory read out and enclose the log. Then disconnect the battery, only then remove the control unit, and create a repair order online. Airbag24 usually needs 3–4 working days for checking, repairing and testing.

The order is a safety measure, since removal comes only once the battery is disconnected. Pack the device well before you send it.

Airbag24 tests the control unit on the test bench, repairs defective components, deletes the stored crash data and carries out a function test. Afterwards your own, repaired 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.
