Airbag control unit with part number P68148044AD

What does the airbag control unit P68148044AD do?

The airbag control unit P68148044AD evaluates the restraint system (SRS) for Jeep. It records the signals from the crash sensors, determines within milliseconds in the event of an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

The device displays faults via the airbag warning light in the instrument cluster. This way the driver can tell that something is wrong with the system.

The part number P68148044AD identifies exactly this control unit. Anyone removing it has the switching centre of the system in front of them, not a secondary component.

Why does the control unit P68148044AD fail?

The most common trigger is crash data stored in the unit after an accident, even if no airbag fired; a normal diagnostic tool does not erase it. Other causes are aged components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes. Airbag24 erases the crash data during the repair.

The stored crash data arises because the unit records an event. Whether an airbag deployed plays no role for the memory.

Beyond that, ageing and the environment must be mentioned. Aged components, cold solder joints, moisture and corrosion on plugs, and voltage spikes from the vehicle electrical system can cause the failure, for example after a jump start.

How can you tell that the P68148044AD is defective?

On the instrument cluster you can recognise a defect by the airbag warning light, which stays on permanently or only intermittently, and by fault messages. In addition, a diagnostic tool cannot reach the control unit, or the fault memory cannot be cleared. In an emergency, airbags or seatbelt pretensioners may then fail to deploy.

The warning light shows the state of the system long before an accident decides anything. If you see it on, have the system checked promptly. Only diagnosis shows whether the control unit itself or a connection behind it is at fault.

How does the repair of the P68148044AD work?

First have the fault memory read out and attach the log. Then disconnect the battery, remove the control unit and create a repair order online. Then send it in; Airbag24 checks, repairs, erases the crash data and tests the unit.

Processing at Airbag24 usually takes 3–4 working days.

The order of steps on the vehicle follows from safety: removal only begins once the battery is disconnected.

At Airbag24, the test bench check is followed by the repair, erasing the crash data and the function test, before your own unit is returned.

The 3–4 working days cover only this work 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.
