Airbag control unit with part number 68615035AA

What does the airbag control unit 68615035AA do?

At 68615035AA the signals from the crash sensors come together: the airbag control unit evaluates them and, in the event of an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered. It monitors the restraint system (SRS) of Dodge continuously. After an accident it stores crash data and locks itself.

It detects faults itself and shows them via the airbag warning light in the instrument cluster.

Why does the control unit 68615035AA fail?

The most common cause is stored crash data after an accident, even without a triggered airbag, which cannot be cleared with a normal diagnostic tool. Further causes on the 68615035AA are ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start. Airbag24 deletes the crash data during repair.

The control unit itself creates the crash data as soon as the accident is registered; a triggered airbag is not needed for this.

The remaining causes concern electronic components and their connections. Solder joints can be cold, moisture attacks plug contacts, and voltage spikes stress the power supply.

How can you tell that the 68615035AA is defective?

A defect in the 68615035AA shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Fault messages and a disturbed diagnostic access also point to it. In an emergency, airbags and seatbelt pretensioners may then not trigger.

The indications at a glance:

• Warning light in the instrument cluster, permanent or intermittent
• Fault message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory cannot be cleared

A single sign proves nothing about the cause yet, but it is a reason for a check.

Which vehicles is the 68615035AA fitted in?

The control unit 68615035AA is fitted in these vehicles: Dodge Durango 3rd generation (2010-2014) and 3rd generation Facelift (from 2014). The decisive factor remains the part number of the unit, not the model name.

We know the following vehicles for this number:

• Dodge Durango 3rd generation (2010-2014)
• Dodge Durango 3rd generation Facelift (from 2014)

Comparing the label on the removed unit only confirms that it is the correct unit. Having the fault memory read out before you remove anything, on the other hand, 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 68328922AB.

How does the repair of the 68615035AA work?
