Airbag control unit with part number 68263741AB

What does the airbag control unit 68263741AB do?

The airbag control unit 68263741AB controls the restraint system (SRS) in Dodge. It evaluates the signals from the crash sensors, decides in the event of an accident within milliseconds on triggering airbags and seatbelt pretensioners, and monitors the system continuously. After an accident, it stores crash data and locks itself.

In everyday use, the unit works unnoticed in the background. It checks the connections to the sensors, the airbags and the seatbelt pretensioners. As soon as something is wrong, it reports this via the airbag warning light in the instrument cluster.

The lock affects the control unit itself. With the part number 68263741AB in hand, you therefore hold the controller that decides on triggering and warning. That is exactly why every defect deserves a close look at this unit and at the connections through which it communicates with the rest of the system.

Why does the control unit 68263741AB fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; an ordinary diagnostic tool cannot delete it. Other causes include ageing electronic components, dry solder joints, moisture and corrosion on plug connections, and voltage spikes. Airbag24 deletes the crash data during the repair.

Crash data is created as soon as the unit records an event that it classifies as an accident. Whether an airbag triggers in the process is irrelevant to the storage, so the problem can also occur when the car looks unscathed from outside.

Further causes may not lie in the accident but in age, environment and power supply:

• ageing electronic components that lose reliability over time
• dry solder joints on the circuit board
• moisture and corrosion on plug connections
• voltage spikes, for example from a weak battery or a jump-start

How can you tell that the 68263741AB is defective?

A defect shows up through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and through a fault message in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

There are also signs during diagnosis. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. If you notice these symptoms, have the system checked promptly.

• airbag warning light in the instrument cluster lights up permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool gets no connection to the control unit
• fault memory cannot be cleared

Even if the vehicle otherwise drives normally, the warning must be taken seriously. The cause does not always lie in the control unit itself, which is why the fault memory is followed by a precise check.

Which vehicles is the 68263741AB fitted in?

The part number 68263741AB is fitted in these vehicles: Dodge Ram DS/DJ/D2 (2009-2018). The part number on the unit is decisive, not the model name in the registration document.

The following list shows the vehicles we have on record for this part number.

• Dodge Ram DS/DJ/D2 (2009-2018)

Before removing the unit, a couple of checks are useful. Comparing the part number on the label with this page only confirms that you have the correct unit in front of you. Have the fault memory read beforehand, because only this result shows whether the control unit 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 68263741AB work?

First have the fault memory read and attach the log, then disconnect the battery and only then remove the control unit. Afterwards, create a repair order online and send the unit in, well packed. Processing at Airbag24 usually takes 3–4 working days.

The order of steps is fixed for safety reasons. You only remove the control unit once the battery has been disconnected.

At Airbag24, the unit is first examined on the test bench. Defective components are repaired, stored crash data is deleted and a function test is carried out. Your own unit is then returned to you.

The processing time of 3–4 working days covers only checking, repairing and testing at Airbag24.

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 68263741AB get to Airbag24?

You send the unit as a parcel, or you book a UPS collection for an extra charge. After the repair, Airbag24 returns the unit by UPS.

Put the printed repair order into the parcel and pack the unit shock-resistant before handing it over.
