Airbag control unit with part number P68046204AD

What does the airbag control unit P68046204AD do?

The airbag control unit P68046204AD is the central control unit of the restraint system (SRS) in Jeep. It evaluates the signals from the crash sensors and decides in an accident, within milliseconds, whether airbags and seatbelt pretensioners are triggered.

In operation, it keeps the entire system under control and reports faults via the airbag warning light in the instrument cluster.

After an accident, the control unit stores crash data and locks itself.

Why does the control unit P68046204AD fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

A normal diagnostic tool cannot erase the crash data. Airbag24 takes care of this during the repair.

Aged electronics, cold solder joints, moisture at the plugs and voltage spikes from a weak battery or a jump start can also cause the failure.

How can you tell that the P68046204AD is defective?

A defect shows on the airbag warning light in the instrument cluster, which lights up permanently or intermittently. An error message may appear as well, or the diagnostic tool finds no connection to the control unit. In this case, airbags and seatbelt pretensioners may fail to trigger in an emergency.

The warning light makes the defect visible and must therefore be taken seriously. The warning remains even if the vehicle continues to drive normally.

Please have the condition checked promptly.
