Airbag control unit with part number P04896137AF

What does the airbag control unit P04896137AF do?

As the central control unit of the restraint system (SRS) of Jeep, the P04896137AF evaluates the signals from the crash sensors. In the event of an accident, it decides within milliseconds which airbags and seatbelt pretensioners are triggered. It monitors the entire system continuously, and after an accident it stores crash data and locks itself.

The system is made up of several sensors and triggers, and the control unit links them together. It detects abnormal conditions and reports them to the driver.

A fault in the control unit therefore affects the entire restraint system and not just a single part of it.

Why does the control unit P04896137AF fail?

Stored crash data is the most common cause in the P04896137AF, even if no airbag was deployed in the accident. The normal diagnostic tool cannot erase it. Other possible causes include aged components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes from a weak battery or jump-starting.

Crash data is therefore an obvious first point in fault diagnosis. It sits in the memory and cannot be removed with the diagnostic tool.

The other causes are due to ageing and environmental influences. Components lose performance over time, solder joints can go cold, and moisture causes corrosion.

How can you tell that the P04896137AF is defective?

The airbag warning light in the instrument cluster indicates a fault in the P04896137AF when it lights up permanently or intermittently. This is accompanied by an error message, a diagnostic tool with no connection to the control unit, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The light is not a guess but the direct message from the system. If you notice it, have the vehicle checked promptly.

Compare the part number on the label of the removed unit with this page. This only shows that it is the right unit. Also have the fault memory read out beforehand; this result shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 5189278AA, 68025632AK, P04896129AF, P04896129AG, P56038973AE, P56038973AF.

How does the repair of the P04896137AF work?

First have the fault memory read out and enclose the log with the package. Then disconnect the battery and then remove the control unit P04896137AF. Next, create a repair order online and send in the well-packed unit.

This order is mandatory for safety reasons. At Airbag24, the unit is examined on the test bench, defective components are repaired, stored crash data is erased and a functional test is carried out. Airbag24 usually allows 3–4 working days for this.

Finally, Airbag24 sends your own unit 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 P04896137AF get to Airbag24?

You send the P04896137AF as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.

The printed repair order goes into the package with the unit, and the unit is packed to withstand shocks.
