Airbag control unit with part number P68068703AC

What does the airbag control unit P68068703AC do?

The airbag control unit P68068703AC is the central unit of the SRS in vehicles from Jeep. It checks the signals from the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system without interruption.

The unit indicates faults it detects via the airbag warning light in the instrument cluster. The light therefore serves as a warning for you as the driver.

After an accident, the unit writes crash data into its memory and locks itself. It is the repair that ends this lock.

Why does the control unit P68068703AC fail?

The most common cause of a fault in the P68068703AC is crash data from an accident, even if no airbag has triggered; a normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture on plug connections and voltage spikes are also possible.

• ageing of the electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

A non-triggered airbag is therefore no proof that there is no crash data.

The other causes concern the electronics and their connections. They come into consideration in general, without it being possible to narrow them down in advance.

Airbag24 erases the crash data as part of the repair.

How can you tell that the P68068703AC is defective?

The airbag warning light in the instrument cluster lights up on the P68068703AC permanently or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool does not find the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

If the warning light comes on, that is a clear signal and calls for an inspection. The problem persists even if the vehicle keeps driving.

A fault search without a read-out brings little certainty. Whether the control unit itself or a cable is affected only the fault memory will show.
