Airbag control unit with part number 68371750AA

What is the function of Airbag Control Unit 68371750AA?

The airbag control unit with part number 68371750AA is an original Mopar control module that serves as the central brain of the occupant protection system in specific Dodge Charger and Challenger models. It processes data from acceleration and crash sensors in real time and determines when to deploy airbags and seatbelt pretensioners.

As a safety-critical component, this control unit is essential for passive vehicle safety. It continuously monitors all connected components of the restraint system, including airbags, seat occupancy mats, and sensors. In the event of a crash, it ensures that the appropriate restraint devices are activated at precisely the right moment to provide optimal protection for occupants.

The proper functioning of this unit is crucial, as a failure can disable the entire airbag system, leaving occupants unprotected in an emergency. It also communicates with other control modules in the vehicle and stores system-relevant fault and event data.

Why does control unit 68371750AA fail?

Failure of control unit 68371750AA is most commonly caused by stored crash data following an accident, which triggers an intentional lockout of the module. Other causes include internal electronic malfunctions, wiring issues, or water damage, all of which can lead to total failure or erratic behavior.

The primary and most frequent cause of failure is the storage of crash data. After an airbag deployment, the control unit locks itself to prevent further operation with a potentially compromised system. This “locked module” reports a permanent fault and must be professionally reset.

Electronic malfunctions are another typical source of failure. Internal components on the circuit board can degrade due to aging, voltage spikes, or moisture exposure, often resulting in persistent error codes that cannot be cleared and necessitate hardware repair.

Wiring problems within the vehicle’s harness can also mimic a control unit malfunction. Broken or crushed wires, as well as loose connectors, may cause the airbag warning light to remain steadily illuminated or flash. Therefore, workshop practice recommends thoroughly inspecting the wiring before removing the control unit.

In rarer cases, the control unit may fail spontaneously without any apparent reason or completely refuse communication via the OBD interface, complicating diagnosis.

How do you recognize a defect in 68371750AA?

A defect in airbag control unit 68371750AA is unmistakably indicated by a permanently illuminated or flashing airbag warning light (SRS light) on the instrument cluster. Often, the control unit can no longer be accessed using a diagnostic tool, or error codes are stored that point to an internal fault.

The most obvious sign is the activated SRS warning light. This light does not extinguish after starting the vehicle, signaling that the entire airbag system is disabled. Continuing to drive is strongly discouraged, as airbags will not deploy in the event of a crash.

During diagnostics at a workshop, the defect is frequently revealed by a lack of communication: the diagnostic tool cannot establish a connection with the airbag control unit. Alternatively, specific error codes are read out, indicating stored crash data or an internal hardware fault within the unit itself.

Following any accident in which airbags or seatbelt pretensioners have deployed, the control unit is guaranteed to be locked and requires professional repair. Even if no external damage is visible, crash event data remains stored internally, preventing further functionality.

In which vehicles is 68371750AA installed?

The Mopar airbag control unit with part number 68371750AA is specifically designed for high-performance Dodge models. It is used across various generations and trim levels of the Dodge Charger, as well as in the Dodge Challenger SRT LC, where it manages the complex restraint system.

At Airbag24, we professionally repair control unit 68371750AA for the following models:

Dodge Charger: Generations 1 through 7, including LX, LD, SRT LX, SRT LD, and Hellcat LD variants (approximately model years 2006–2023)

Dodge Challenger: SRT LC

How is 68371750AA professionally repaired?

Professional repair of 68371750AA begins with an initial inspection and reading of fault and crash data. Stored crash data is then erased using specialized software, and any internal electronic faults are rectified. A final functional test confirms full operability before the unit is returned to the customer.

After you send the control unit to Airbag24, a proven repair process begins. First, the unit is read using the latest diagnostic software to identify the exact cause of the fault—whether it’s crash data or an internal defect.

The core of the repair is often the “Airbag Reset.” During this step, crash data stored after an accident is completely and safely erased from the control unit’s memory using specialized software, thereby removing the module’s lockout.

If an additional internal electronic defect is present, our technicians open the unit and perform targeted soldering or replace faulty components on the circuit board. The control unit is then resealed.

Finally, a comprehensive functional test ensures that the control unit communicates flawlessly and correctly controls all systems. We provide 2 years' statutory liability for defects on every repair.

What are the benefits of a repair?

Repairing the 68371750AA offers significant cost savings—often exceeding 70%—compared to purchasing a new, expensive part, which can range from €500 to over €1,000. A refurbished original component is also a sustainable, reliable solution with full functionality and warranty.

A key advantage is the price: refurbishment costs only a fraction of what a new manufacturer‑supplied control unit would cost. You regain full safety and functionality without straining your budget.

A repaired control unit is “plug-and-play.” Since it’s your original part, no coding or programming at the workshop is required after reinstallation.

Moreover, repair is a resource‑efficient alternative to buying new, actively contributing to environmental protection. You receive 2 years' statutory liability for defects on the completed repair.
