Airbag control unit with part number P68069304AA

What does the airbag control unit P68069304AA do?

The airbag control unit P68069304AA controls the restraint system (SRS) in Dodge vehicles. It checks the signals from the crash sensors continuously and determines in an emergency which airbags and seatbelt pretensioners fire. It detects faults in the system and displays them via the airbag warning light.

The decision is made in a fraction of a second in an accident. After a crash, the unit creates crash data and switches to the locked state.

The unit is therefore a central part of the safety technology in this vehicle.

Why does the control unit P68069304AA fail?

Stored crash data is the most common cause, even if no airbag was triggered in the accident. A normal diagnostic tool does not erase it. In addition, there are aged components, cold solder joints, moisture and corrosion at plugs, and voltage spikes.

The crash data remains in the unit's memory after the accident and cannot be removed with common tools.

The other causes act over a longer period, for example through ageing of the electronics or moisture in the plug connections. Voltage spikes arise, for example, from a weak battery or when starting with a jump start.

How can you tell that the P68069304AA is defective?

The airbag warning light in the instrument cluster lights up permanently or only intermittently, and an error message appears in the instrument cluster. The diagnostic tool finds no connection to the control unit, and a fault memory cannot be erased.

In an emergency, airbags and seatbelt pretensioners may then possibly fail to deploy. A lit warning light is an unambiguous sign. Have the system checked promptly.

The warning light belongs to the system and reports faults directly. The condition can be read from the light without any tool being needed.

Which vehicles is the P68069304AA fitted in?

The control unit P68069304AA is fitted in these vehicles: Dodge Caliber PM (2006-2009) and PM Facelift (2009-2011). The assignment is based on this part number.

In detail, the following vehicles are concerned:

• Dodge Caliber PM (2006-2009)
• Dodge Caliber PM Facelift (2009-2011)

First check whether the part number on the label of the removed unit matches the information on this page. This only ensures that the right unit is present. Regardless of that, have the fault memory read out before removal. Only this result shows whether the control unit itself is defective or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 4672602AB, 4896616AA, 4896616AB, 68148034AA, P04672603AE, P04896621AE.

How does the repair of the P68069304AA work?

Have the fault memory read out and enclose the log with the unit before you disconnect the battery. Only then remove the control unit and create a repair order online. Testing, repair and checking at Airbag24 are typically scheduled for 3–4 working days.

Afterwards pack the unit well and send it in. Airbag24 checks it on the test bench, replaces defective components, erases the stored crash data and carries out a function test. The unit then returns to you.

The log helps, because it records the condition before removal.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit P68069304AA get to Airbag24?

Either you send the unit as a parcel yourself, or you book a UPS collection for an extra charge. UPS handles the return after the repair.

Enclose the printed repair order in the parcel, and the unit must be packed shockproof.
