Airbag control unit with part number P68148037AA

What does the airbag control unit P68148037AA do?

The airbag control unit P68148037AA is responsible for the restraint system (SRS) of Jeep. It evaluates the sensor signals, selects the right airbags and seatbelt pretensioners within milliseconds in an accident, and monitors the system continuously. Faults that occur are reported via the airbag warning light.

During operation, monitoring runs unobtrusively. The unit checks components and wiring for plausibility.

If an accident has happened, the unit stores crash data and locks itself. Every diagnosis after that meets exactly this state.

Why does the control unit P68148037AA fail?

The most common cause is crash data that is present in the unit after an accident, even without an airbag having deployed. Ageing, cold solder joints and moisture, as well as voltage spikes, also count.

Crash data cannot be removed with a normal diagnostic tool; Airbag24 deletes it during the repair. The other triggers in detail:

• ageing of the electronic components
• cold solder joints
• moisture and corrosion at the plug connections
• voltage spikes, for example with a weak battery or after a jump start

How can you tell that the P68148037AA is defective?

A defect shows itself through the airbag warning light in the instrument cluster, a fault message in the instrument cluster, a missing connection between the diagnostic tool and the control unit, or a fault memory that cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then not deploy.

Typical signs at a glance:

• The airbag warning light in the instrument cluster stays on or comes on intermittently.
• A fault message appears in the instrument cluster display.
• Establishing a connection to the control unit via the diagnostic tool fails.
• An attempt to clear the fault memory fails.

The warning light must not be ignored, even if the vehicle appears to drive normally. Only reading out the fault memory reveals which cause lies behind it.

Which vehicles is the P68148037AA fitted in?

The list shows whether your car is affected before you take action. The airbag control unit P68148037AA is fitted in these vehicles: Jeep Compass MK (2007-2010) and MK Facelift (2011-2016).

The basis is the data we hold for this part number.

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

First, have the fault memory read out, because its log shows whether the control unit is defective or whether a plug or cable is the cause. Comparing the part number on the label with this page only confirms that it is the right unit.

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

How does the repair of the P68148037AA work?

Have the fault memory read out first, and enclose the log. Then disconnect the battery; only afterwards remove the control unit. Online you create a repair order and send the unit in well packed.

Then the unit goes to the test bench: Airbag24 checks the unit, replaces defective components, removes the crash data and tests the function. The processing at Airbag24 is usually 3–4 working days; this refers only to checking, repairing and testing, while your steps and the shipping are not included.

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 P68148037AA get to Airbag24?

You can send the unit as a parcel or book a UPS collection for an extra charge. Airbag24 sends it back to you by UPS after the repair.

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