Airbag control unit with part number 68063119AF

What does the airbag control unit 68063119AF do?

The airbag control unit 68063119AF controls the restraint system of Chrysler and Dodge. It processes the measurement signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners fire, and monitors the system continuously. After an accident it stores crash data and locks itself.

If the unit detects a fault, it displays it via the airbag warning light in the instrument cluster.

While driving you do not notice the unit; it works in the background.

Why does the control unit 68063119AF fail?

The most common cause with the 68063119AF is stored crash data after an accident, even without an airbag having deployed. Other causes are aged electronics, damp plug connections and voltage spikes.

• Aged electronic components whose function declines over time.
• Cold solder joints that only intermittently make contact.
• Moisture and corrosion at plug connections.
• Voltage spikes, for example from a weak battery or a jump start.

A normal diagnostic tool cannot erase crash data, so it is among the first points to check when fault-finding.

Which of the other causes actually applies only becomes clear from testing the unit.

How can you tell that the 68063119AF is defective?

Typical signs on the 68063119AF are an airbag warning light in the instrument cluster that lights up permanently or intermittently, and a fault message in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

• The airbag warning light lights up permanently or intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool cannot establish a connection to the control unit.
• The fault memory cannot be cleared.

The warning light reports the fault as soon as the unit detects it, and is therefore the most direct indication.

A missing connection to the diagnostic tool can also be caused by a plug or a cable, so it does not necessarily originate in the control unit itself.

Compare the part number on the label of the removed unit with this page; this only tells you that it is the correct unit. In addition, have the fault memory read out, because only this log shows whether the control unit is defective or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 05094018AL, 05094018AM, 5094019AK, 5WK43858, 68062118AE, 68062118AF.

How does the repair of the 68063119AF work?

First have the fault memory read out at the 68063119AF and enclose the log. Then disconnect the battery, only then remove the control unit and create a repair order online. You send in the well-packed unit; processing at Airbag24 usually takes 3–4 working days.

This sequence is prescribed for work on the restraint system.

At Airbag24 the unit first goes onto the test bench. Afterwards defective components are repaired, crash data erased and a function test carried out before you receive your own unit back.

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 68063119AF get to Airbag24?

You send the control unit 68063119AF as a parcel or arrange a UPS collection for an extra charge. After the repair, Airbag24 sends the unit back to you by UPS.
