Airbag control unit with part number P68239524AB

What does the airbag control unit P68239524AB do?

The airbag control unit P68239524AB forms the centre of the restraint system for Jeep. It evaluates the signals from the crash sensors and monitors the system constantly. It reports faults via the airbag warning light.

The decision on triggering airbags and seatbelt pretensioners is made within milliseconds according to defined evaluation rules.

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

Why does the control unit P68239524AB fail?

The P68239524AB most often fails because of crash data stored in the unit after an accident, even without a deployed airbag. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes from weak batteries or jump starts.

A normal diagnostic tool cannot remove the records. This also applies when the accident was minor.

Electronic components also age over time. Solder joints may have been made cold and come loose, so that a contact briefly breaks.

Moisture and corrosion at plug connectors disrupt signal transmission. Voltage spikes, for example from a weak battery or starting with a jump start, put additional strain on components.

How can you tell that the P68239524AB is defective?

The airbag warning light in the instrument cluster shows the fault in the P68239524AB by lighting up permanently or intermittently. Further signs are a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. A prompt check is therefore worthwhile rather than watching the light for longer.

The diagnostic tool reads the fault memory. Without this connection the cause cannot be narrowed down.

Which vehicles is the P68239524AB fitted in?

The P68239524AB is fitted in these vehicles: Jeep Cherokee KL Facelift (2018-2023) and KL (2013-2018).

These models are known to us for this part number:

• Jeep Cherokee KL Facelift (2018-2023)
• Jeep Cherokee KL (2013-2018)

First compare the part number on the label of the removed unit with this page. That only shows that you have the right unit in hand. Also have the fault memory read out before removal, because only the log shows whether the control unit itself or a plug and cable is the cause.

For the same vehicles, we also repair control units with the part numbers 68355363AB.

How does the repair of the P68239524AB work?

First have the fault memory read out and attach the log. Then disconnect the battery, and only then remove the P68239524AB, and create a repair order online for shipping.

This sequence protects you during removal. Afterwards pack the unit so that nothing can shift.

Airbag24 checks the unit on the test bench, repairs defective components, erases stored crash data and carries out a function test. Processing at Airbag24 itself usually takes 3–4 working days before your own unit goes back.

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 P68239524AB get to Airbag24?

You send the P68239524AB as a parcel or book a UPS collection for an extra charge. After the repair Airbag24 returns the control unit to you by UPS.

Put the printed repair order into the parcel and pack the control unit shockproof.
