Dodge Sprinter airbag control unit repair⁽²⁾

What should I pay attention to with Dodge Sprinter airbag control units?

The Dodge Sprinter airbag control unit evaluates the crash sensors, triggers the airbags and belt tensioners in a crash, and monitors the entire system. It reports faults via the airbag warning light. After an accident it stores crash data and locks itself.

The Dodge Sprinter is a van that was offered in North America under the Dodge brand. If the airbag warning light stays on permanently, this points to a fault in the system. Whether the control unit is the cause can only be determined after the fault memory has been read out.

Airbag24 repairs your own airbag control unit at our workshop in Berlin. Whether a particular unit can be repaired is established by the check after it arrives.

Which Dodge Sprinter generations are there?

The Dodge Sprinter was built in two series: T1N from 2003 to 2006 and NCV3 from 2007 to 2009. The series differ in model year and in the part numbers of the control units, so identifying the correct series before you send the unit in is important.

• T1N (2003–2006) – first series, offered as the Dodge version for the North American market
• NCV3 (2007–2009) – next generation of the model, likewise offered for the North American market

You can tell which series is fitted to your vehicle from the part number on the control unit and from the model year.

How do I identify my Dodge Sprinter airbag control unit?

The part number on the label of the control unit determines the exact version. In addition, check the model year and equipment of your vehicle, as both show which variant is fitted.

The following part numbers are recorded for the Dodge Sprinter. The list does not claim to be complete, so compare the number on your unit with it.

• 5119435AA (T1N)
• 68029747AA (NCV3)
• 68029750AA (NCV3)
• 68029771AA (NCV3)

Examples of fault codes are B2208 (internal fault in the control unit), U0151 (communication with the control unit lost) and B1B02 (driver airbag, firing circuit 1: open circuit). A single code does not prove that the control unit is faulty; only the check shows the cause.

What airbag equipment does the Dodge Sprinter have?

According to the sources, front airbags for driver and front passenger were standard on both series. Side and curtain airbags were available as an option on the NCV3, while the information for the T1N series is not clearly documented.

For the T1N series, equipment overviews for model year 2004 list two front airbags as standard. The sources contradict each other on whether side airbags were offered.

On the NCV3 series (2007 to 2009), side and curtain airbags were optional according to the equipment lists available. The vehicle documentation or the equipment list shows which airbags are fitted in your vehicle.

An airbag control unit controls the fitted airbags. If a fault is present, the fault memory is read out first. The battery is disconnected and the control unit removed; a specialist workshop should carry out these steps, as the airbag system is safety-relevant. You then create a repair order online and send the unit to Airbag24.

Processing usually takes 3–4 working days (checking, repairing, testing). The repaired control unit returns with all vehicle data and is ready for use immediately after refitting — coding or programming is not necessary.
