Airbag control unit with part number 68492238AD

What does the airbag control unit 68492238AD do?

The airbag control unit 68492238AD controls the restraint system (SRS) of Dodge. It evaluates the crash sensors and determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

During operation, the unit checks the components continuously. If it detects a fault, the airbag warning light in the instrument cluster lights up.

If an accident has occurred, the control unit stores crash data and is locked afterwards.

Why does the control unit 68492238AD fail?

Stored crash data from an accident is the most common cause: it remains in the unit even if no airbag has deployed, and a normal diagnostic tool cannot erase it. Other causes are aged electronics, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Electronic components change with age, and solder joints can go cold. In addition, moisture causes the plug contacts to corrode.

Voltage spikes occur when, for example, the battery is weak or an external power source is connected.

How can you tell that the 68492238AD is defective?

A defect on the unit shows up as the airbag warning light, which lights up permanently or intermittently, and as a fault message in the instrument cluster. You will also recognise it when the diagnostic tool makes no contact or the fault memory cannot be cleared.

Typical signs at a glance:

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

In the event of such a defect, the airbags and seatbelt pretensioners may fail to deploy in an emergency. Please have the fault checked promptly.

Which vehicles is the 68492238AD fitted in?

The airbag control unit 68492238AD is fitted in these vehicles: Dodge Durango 3rd generation (2010-2014) and 3rd generation Facelift (from 2014). As a check, compare the label on the removed unit with this page and have the fault memory read out.

The list of assigned vehicles is as follows:

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

A comparison of the part number on the label only shows whether the unit fits. It does not establish whether it is the cause. Therefore have the fault memory read out, because the log shows whether the control unit is defective or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 68328922AB.

How does the repair of the 68492238AD work?

Have the fault memory read out beforehand and attach the log to the unit.

Processing at Airbag24 takes 3–4 working days as a rule for the check, repair and function test.

Airbag24 examines the control unit on the test bench, repairs the defective components, deletes the crash data and carries out a function test. Returning your own unit to you completes the process.

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.
