Airbag control unit with part number 68163807AA

What is the function of the airbag control unit 68163807AA?

The airbag control unit with part number 68163807AA is the central control module for the occupant protection system (SRS) in vehicles such as the Dodge Journey. Its primary task is to process sensor data to precisely deploy the airbags and seatbelt pretensioners in the event of a crash, then permanently store the crash data.

As an SRS module (Supplemental Restraint System), it continuously monitors the vehicle’s acceleration and yaw rate sensors. If the system detects a collision exceeding predefined thresholds, it sends ignition signals to the relevant pyrotechnic components within milliseconds.

After deployment, the control unit locks itself by storing so‑called crash data in its internal memory. This is a manufacturer‑imposed safety measure that prevents reuse without professional diagnostics and repair, while also activating the airbag warning light.

Why does the control unit 68163807AA fail?

The most common cause of failure for the control unit 68163807AA is the storage of crash data after an accident, which triggers a system‑wide lockout. Other causes include internal electronic component failures, communication issues with the diagnostic system, or physical damage due to water ingress.

The primary reason for failure is the manufacturer‑specified lockout following a crash. The unit remains functional but locked; airbags stay deactivated, and the SRS warning light stays illuminated until the crash data is professionally reset by a specialist.

In addition, hardware faults on the circuit board can occur. Defective electronic components—such as those supplied by manufacturers like Bosch or Delphi—can lead to total failure, often indicated by the error code “Internal Control Unit Error” or a loss of communication.

Rarely, external factors like water damage cause corrosion on the circuit board and short circuits. A disrupted communication link between the control unit and the vehicle’s sensors is another typical symptom pointing to an internal defect.

How do you recognize a fault in the airbag control unit 68163807AA?

A defective airbag control unit 68163807AA typically manifests as a permanently lit or flashing SRS airbag warning light on the instrument cluster. This indicates that the restraint system is locked and the airbags would not deploy in the event of another crash.

The activated warning signal is the clearest indication of a problem, unequivocally urging the driver to have the system inspected immediately, as vehicle safety is no longer fully guaranteed.

During workshop diagnostics, it may happen that no communication can be established with the airbag control unit. The diagnostic tool receives no response, suggesting a severe internal hardware fault.

In other cases, although the fault memory can be read, error codes such as “Crash Data Stored” or “Control Unit Faulty” appear. These errors cannot be cleared using standard workshop scanners and require specialized repair.

In which vehicles is the control unit 68163807AA installed?

The airbag control unit with part number 68163807AA is specifically used in Dodge vehicles. It is found primarily in the first generation of the Dodge Journey—including its facelifted version—as well as in the older Dodge 600 model. Repairing this unit represents a cost-effective alternative for these models.

At Airbag24, we offer professional repair of the control unit 68163807AA for the following specific models and series:

Dodge: Journey 1st Generation (2008–2010), Journey 1st Generation Facelift (2010–2020), 600 1st Generation

How is the control unit 68163807AA professionally repaired?

Professional repair of the control unit 68163807AA at Airbag24 includes a precise initial analysis to identify the fault, targeted restoration through clearing crash data or replacing defective components, followed by a final functional test on a test bench to ensure full safety.

Upon receipt of the removed control unit at Airbag24, our technicians perform a comprehensive diagnosis to determine the exact cause of the failure—whether it’s simply a data lock after an accident or a deeper hardware issue.

The next step involves actual repair: stored crash data is completely and irreversibly erased from the module’s internal memory. If there is electronic damage, the faulty components on the circuit board are expertly replaced with new, high‑quality parts.

Finally, each repaired control unit undergoes rigorous quality inspection. On a specially designed simulator, the correct functionality of all systems is verified. Following successful testing, the device is fully operational again and is returned to you with a 12-month warranty.
