Airbag control unit with part number P68148022AA

What does the airbag control unit P68148022AA do?

The P68148022AA is the airbag control unit for vehicles of the make Fiat and forms the central control unit of the restraint system. It evaluates the crash sensors and decides in the event of an accident which airbags and seatbelt pretensioners are triggered.

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

Why does the control unit P68148022AA fail?

The most common cause with the P68148022AA is stored crash data after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this crash data.

Other causes that may come into consideration are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

The repair at Airbag24 erases the crash data.

How can you tell that the P68148022AA is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as there is a fault in the P68148022AA. This is accompanied by a fault message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. If the system shows such signs, have it inspected promptly.
