Airbag control unit with part number P04672611AB

What does the airbag control unit P04672611AB do?

The airbag control unit P04672611AB coordinates the restraint system (SRS) of Jeep. Using the crash sensors, it recognises an accident and determines within milliseconds which airbags and seatbelt pretensioners fire. During operation it monitors the system and reports faults via the airbag warning light.

The control works closely with the sensors and triggers. After an accident, the unit stores crash data and locks itself.

Because all triggering runs through this one unit, its function is central to safety in the vehicle.

Why does the control unit P04672611AB fail?

The most common cause of a failure of the P04672611AB is crash data stored after an accident, even if no airbag has deployed. Aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes come on top of this.

A normal diagnostic tool cannot remove this data.

The other causes in brief:

• aged electronic components that lose performance over time
• cold solder joints on the circuit board
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Which of these applies in an individual case is only shown by the examination of the unit.

How can you tell that the P04672611AB is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently if there is a defect in the P04672611AB. In addition, an error message appears in the instrument cluster, the diagnostic tool has no connection to the control unit, and the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

The light is the first sign you will notice in everyday use, because it sits in your field of view.

An error message alone does not prove that the control unit itself is affected. Only the readout shows that.

Which vehicles is the P04672611AB fitted in?

This assignment applies to Jeep models with this control unit. The P04672611AB is fitted in these vehicles: Jeep Patriot MK (2007-2010) and MK Facelift (2010-2016).

These vehicles are recorded in our data for this part number:

• Jeep Patriot MK (2007-2010)
• Jeep Patriot MK Facelift (2010-2016)

First compare the part number on the label of the removed unit with this page; this only ensures that it is the right unit. Also have the fault memory read out, because only this result shows whether the control unit 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 68232710AD, P68148039AB, P68186646AA, P68232716AC, P68232716AD.

How does the repair of the P04672611AB work?

You read out the fault memory first and enclose the log, then disconnect the battery and only then remove the control unit P04672611AB; next, create a repair order online and send the well-packed unit in. Airbag24 checks it on the test bench, repairs defective components, erases stored crash data and carries out a function test, then your own unit is returned to you. Processing at Airbag24 usually takes 3–4 working days.

The order protects you when working on the airbag system.

At Airbag24, the check on the test bench is followed by the repair and then the function test.

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 P04672611AB get to Airbag24?

You hand the control unit P04672611AB to a parcel service or book a UPS collection for an extra charge. After the repair, Airbag24 returns the unit to you by UPS.

Pack the printed repair order into the parcel and pack the unit shockproof.
