Airbag control unit with part number P68148038AA

What does the airbag control unit P68148038AA do?

The airbag control unit P68148038AA is the switching centre of the restraint system (SRS) for Jeep. It receives the crash sensor signals, decides in an emergency within milliseconds on airbags and seatbelt pretensioners, and checks the system continuously.

The unit indicates faults via the airbag warning light in the instrument cluster, so you notice it in everyday use.

If it is involved in an accident, it secures crash data and locks itself.

Why does the control unit P68148038AA fail?

If the P68148038AA fails, stored crash data from an accident is the leading cause, even when no airbag has triggered. Aged electronics, cold solder joints, moisture and corrosion, and voltage spikes are added to this.

Stored data of this kind stays in the unit until Airbag24 removes it during the repair. Workshop tools cannot reach these entries.

Further stresses come from outside: moisture and corrosion at connectors, voltage spikes with a weak battery or jump-starting, and components that have grown old over the years.

How can you tell that the P68148038AA is defective?

A defect in the P68148038AA becomes apparent through the airbag warning light in the instrument cluster, which stays on permanently or only intermittently.

An error message appears alongside it, and the diagnostic tool finds no connection to the control unit. In addition, the fault memory cannot be cleared.

If the diagnostic tool cannot establish a connection and the fault memory cannot be cleared, a problem in the control unit is likely.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger, so do not ignore the display.

Which vehicles is the P68148038AA fitted in?

The P68148038AA is fitted in these vehicles: Jeep Compass MK (2007-2010) and MK Facelift (2011-2016).

This overview shows the assignment:

• Jeep Compass MK (2007-2010)
• Jeep Compass MK Facelift (2011-2016)

Compare the part number on the label of the removed unit with this page; that only establishes that you have the right unit. Whether the control unit itself is defective, or a connector or cable is the cause, is shown only by reading out the fault memory. So have it read out before removal.

For the same vehicles, we also repair control units with the part numbers P68186642AD.

How does the repair of the P68148038AA work?

The repair of the P68148038AA runs in this order: read out the fault memory and attach the log, then disconnect the battery and only then remove the control unit. Processing at Airbag24 usually takes 3–4 working days.

You then create the repair order online and send the well-packed unit.

At Airbag24 the control unit is examined on the test bench, defective components are replaced, crash data is deleted, and a function test is carried out. The return of your own unit follows.

The sequence during removal applies because the airbag system is involved. 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 P68148038AA get to Airbag24?

Your control unit P68148038AA comes to Airbag24 by parcel; alternatively UPS collects it for an extra charge. After the repair, UPS brings the unit back to you.

The printed repair order and the shock-resistantly packed unit go in the parcel.
