Airbag control unit with part number P68046001AD

What does the airbag control unit P68046001AD do?

The airbag control unit P68046001AD coordinates the restraint system (SRS) for Jeep and reads the crash sensors. In an emergency it decides within milliseconds which airbags and seatbelt pretensioners fire. It detects faults itself and reports them via the airbag warning light.

During operation the control unit continuously checks the connections and circuits that lead to the triggers. After an accident it stores crash data and locks itself.

Because the unit is so central, its electronics are thoroughly checked during a repair.

Why does the control unit P68046001AD fail?

The most common cause of the P68046001AD failing is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage peaks are also possible causes.

The unit creates the crash data as soon as it registers an accident, whether or not an airbag fires.

Voltage peaks occur, for example, with a weak battery or a jump start, and can affect the electronics.

How can you tell that the P68046001AD is defective?

On the P68046001AD, the airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears, the diagnostic tool does not connect to the control unit, and the fault memory persists. Airbags and seatbelt pretensioners may then not be able to deploy in an emergency.

The light shows the defect, regardless of how the vehicle behaves in everyday use.

Before you touch the control unit, write down the messages and note when the light comes on.
