Airbag control unit with part number 68105432AF

What is the function of the airbag control unit 68105432AF?

The airbag control unit with part number 68105432AF is the central control module of the occupant restraint system (SRS) in the Chrysler Town & Country. Its task is to analyze data from crash sensors and, in the event of an accident, deploy the airbags and seatbelt pretensioners within milliseconds to protect occupants.

As the “brain” of the passive safety system, this module continuously monitors all connected components, such as impact sensors, seat occupancy mats, seatbelt pretensioners, and the airbag modules themselves. It performs a self-test every time the vehicle is started and indicates any malfunctions via the warning light on the dashboard.

The proper functioning of this control unit is critical for safety. Accurate signal processing and activation of the restraint systems are essential to ensure the best possible protection for drivers and passengers in an emergency.

Why does the airbag control unit 68105432AF fail?

The most common cause of failure for the control unit 68105432AF is the storage of crash data after an accident. Other defects arise from water damage leading to internal corrosion, as well as damaged wiring, faulty connections, or defective plug-in connectors to the rest of the SRS system.

After a traffic accident in which the airbags have deployed, the control unit stores so‑called crash data. For safety reasons, these data permanently lock the module and prevent it from triggering again. The unit must then be professionally reset or replaced to restore full functionality of the airbag system.

Electrical malfunctions caused by moisture are another widespread issue. Ingressing water can lead to short circuits on the circuit board and corrosion of sensitive components, unpredictably impairing the control unit’s performance.

The peripheral components can also cause or mimic a defect in the control unit. Broken connections due to damaged cables or corroded connectors between the control unit and the sensors or airbags likewise result in error messages and system failure.

How do you recognize a defect in the control unit 68105432AF?

A defect in the airbag control unit 68105432AF typically manifests as a constantly illuminated or intermittently flashing airbag or SRS warning light on the dashboard. Error messages may also appear on the vehicle’s display, or the warning light might not illuminate at all during the post‑start system check.

The clearest symptom is the persistently lit warning light on the dashboard, signaling to the driver that the occupant restraint system has a fault and may fail to operate—or operate incorrectly—in the event of another accident.

An intermittent illumination of the warning light often points to a loose connection or an emerging defect, potentially caused by loose plug‑in connectors or internal issues within the control unit.

In some cases, the defect is indicated by specific error messages on the vehicle’s information display. During diagnostics at a workshop, the control unit may even become unresponsive, unable to communicate with the diagnostic tool.

In which models is the control unit 68105432AF installed?

The airbag control unit with part number 68105432AF is specifically designed for vehicles manufactured by Chrysler. It is primarily used in the fifth generation of the Chrysler Town & Country, which enjoyed a long production run and widespread availability.

At Airbag24, we offer repair services for the control unit 68105432AF for the following vehicle model:

Chrysler: Town & Country, Fifth Generation (1990–2016)

Is repairing the control unit 68105432AF worthwhile?

Yes—repair is a technically and economically sensible alternative to purchasing a new unit. It can save you 50–70% compared to the cost of a replacement part. Additionally, the original vehicle coding remains intact, eliminating the need for time‑consuming reprogramming at the workshop.

The financial advantage is substantial. While a new control unit from the manufacturer often comes at a high price, professional repair costs only a fraction of that. At the same time, the functionality and safety of the repaired unit are fully restored.

Another benefit is that the repaired control unit is immediately ready for use (plug-and-play). Since the vehicle’s original configuration is preserved, there are no additional workshop expenses or time required for training or coding a new unit.

Two years' statutory liability for defects is provided on every repair performed, offering added peace of mind. If a repair proves technically impossible, remanufactured replacement control units represent a tested and immediately available alternative.

How does the repair process work at Airbag24?

Upon receipt of the removed control unit at Airbag24, a systematic diagnosis is first carried out to pinpoint the exact source of the fault. Subsequently, crash data is erased, defective components are replaced, and all functions are verified on a test bench before the device is returned.

It is recommended to read out the vehicle’s fault memory prior to removing the control unit. This information assists technicians in conducting a targeted analysis. After removal, the unit is securely packaged and sent to Airbag24.

At the repair laboratory, restoration takes place, including rectification of identified defects—such as resetting crash data, repairing water damage, or replacing faulty electronic components. Each unit undergoes rigorous quality control.

Finally, a comprehensive final inspection is conducted, simulating all components associated with the airbag system to ensure flawless operation. Two years' statutory liability for defects is provided on the repair.
