Airbag control unit with part number P68148034AC

What does the airbag control unit P68148034AC do?

The airbag control unit P68148034AC is the central control unit of the restraint system (SRS) for Dodge. It evaluates the signals from the crash sensors and in an accident determines within fractions of a second which airbags and seatbelt pretensioners are triggered.

Between events the unit keeps working in the background and checks the entire system. A detected fault is indicated via the airbag warning light in the instrument cluster.

After an accident the control unit stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit P68148034AC fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A typical diagnostic tool cannot remove this data. Other causes are ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or jump-starting.

That no airbag has deployed does not mean the unit has stored no data. The crash data remains in the memory and can only be deliberately removed during a repair.

The other causes can concern the electronics and their connections. Moisture, corrosion and voltage spikes attack the components, and a cold solder joint can come loose temporarily under load.

How can you tell that the P68148034AC is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be erased. In an emergency airbags and seatbelt pretensioners may then possibly not deploy.

The warning light is shown on the dashboard and is the first visible hint for you. Anyone who ignores it loses track of the condition of the system.

If the lamp does not go out after the ignition is switched on, have the system checked promptly. Even a message that appears only intermittently justifies reading out the fault memory.
