Airbag control unit with part number P68148022AB

What does the airbag control unit P68148022AB do?

In the vehicle from Fiat, the airbag control unit P68148022AB takes over control of the SRS restraint system. It processes the signals from the crash sensors and decides in an impact, within milliseconds, which airbags and seatbelt pretensioners to trigger. It also monitors all components continuously and displays faults.

After an accident, it stores crash data and locks itself.

Faults are indicated by the airbag warning light in the instrument cluster.

Why does the control unit P68148022AB fail?

The most common cause is stored crash data, even if no airbag was triggered. Other causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion on the plugs
• voltage spikes, for example from a weak battery or a jump start

A normal diagnostic tool cannot delete the crash data. Airbag24 removes it during the repair.

How can you tell that the P68148022AB is defective?

A defect in the P68148022AB shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

As long as this fault exists, airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light is therefore a signal that you must take seriously.
