Airbag control unit with part number 68299147AD

What does the airbag control unit 68299147AD do?

In the restraint system of Jeep, the airbag control unit 68299147AD takes over the evaluation. It processes the signals from the crash sensors and, in the event of an accident, triggers the appropriate airbags and seatbelt pretensioners within milliseconds. After an accident, the unit stores crash data and locks itself.

At the same time, it checks the system continuously for faults. If one is found, it appears on the airbag warning light. Only a repair lifts the lock.

Why does the control unit 68299147AD fail?

The most common cause on the 68299147AD is crash data stored after an accident, even if no airbag has deployed. This data cannot be erased with a standard diagnostic tool. Other possible causes include aged components, cold solder joints, moisture and corrosion on connectors, and voltage spikes, for example from a weak battery or a jump start.

Airbag24 erases the crash data during the repair, so these entries no longer exist afterwards.

The remaining causes involve ageing and wear of components, solder joints that have gone cold, and moisture or corrosion at plug connections.

How can you tell that the 68299147AD is defective?

On the 68299147AD, the defect is mainly indicated by the airbag warning light in the instrument cluster, which stays on permanently or comes on intermittently. Fault messages in the instrument cluster may also appear, the diagnostic tool cannot find the control unit, or the fault memory remains.

In the event of a defect, airbags and seatbelt pretensioners may not deploy in an emergency, so this warning must be taken seriously.

Which vehicles is the 68299147AD fitted in?

The 68299147AD is assigned to these vehicles: Jeep Compass MP (2016-2020) and MP Facelift (from 2020).

Here is the list of vehicles:

• Jeep Compass MP (2016-2020)
• Jeep Compass MP Facelift (from 2020)

Comparing the part number with the label on the removed unit shows whether it is the correct unit; it says nothing about the cause. What matters is the fault memory that you have read out beforehand, because it shows whether the control unit is defective or whether a connector or cable is causing the problem.
