Airbag control unit with part number P68241442AA

What does the airbag control unit P68241442AA do?

The airbag control unit P68241442AA coordinates the restraint system for Dodge and evaluates the signals from the crash sensors. In an emergency it determines within milliseconds which airbags and seatbelt pretensioners are triggered.

At the same time it monitors the system and reports faults via the airbag warning light. After an accident it stores crash data and locks itself; the lock is only lifted by a repair.

The interplay of sensors, control unit and triggers only works if the control unit itself functions properly.

Why does the control unit P68241442AA fail?

Crash data stored after an accident is the most common cause, even if no airbag has deployed. Further causes are ageing components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

The crash data is recorded in the control unit and cannot be erased with an ordinary diagnostic tool. That is exactly why a fault persists after reading out without a repair.

Ageing components and cold solder joints show themselves over time. Moisture and corrosion on plug connectors disturb the contact.

Voltage spikes, for example from a weak battery or when jump leads are connected, put a strain on the electronics.

How can you tell that the P68241442AA is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently, and an error message accompanies it. A missing connection to the diagnostic tool and a fault memory that cannot be cleared also point to a defect.

The warning light passes on the detection of a fault directly. As long as it is lit, airbags and seatbelt pretensioners may not deploy in an emergency.

Even if the vehicle seems normal in everyday use, you should have these signs checked.

The label comparison only shows whether you have removed the correct unit; it does not show the cause. Therefore have the fault memory read out before removal, because only this result reveals whether the control unit is defective or whether a plug or cable is affected.

For the same vehicles, we also repair control units with the part numbers P68241442AB, P68303231AA, P68335041AA, P68335041AB.

How does the repair of the P68241442AA work?

First have the fault memory read out and attach the log to the unit. Then disconnect the battery, remove the control unit and create a repair order online. Only then send the well-packed unit in.

Airbag24 checks the control unit on the test bench, replaces components where necessary, erases the crash data and carries out a function test. Processing at Airbag24 usually takes 3–4 working days.

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 P68241442AA get to Airbag24?

You take care of the shipment yourself by parcel, or you book a UPS collection for an extra charge. The return shipment after the repair is made by UPS.

Put a printed repair order into the parcel, and the control unit must be packed shock-resistant.
