What is a Chrysler Voyager AS airbag control unit?
The Chrysler Voyager AS airbag control unit is the central safety unit in your vehicle, which activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores important crash data, and ensures the proper functioning of all safety-relevant airbag modules.
This electronic control unit, also known as the airbag ECU or SRS module, is critical to the safety of occupants in the Chrysler Voyager GS and RG series from 1999 to 2016.
It communicates with the vehicle's electrical system and is responsible for fault diagnosis of the entire airbag system.
Why is the Chrysler Voyager AS airbag control unit defective?
A Chrysler Voyager AS airbag control unit is often defective because it permanently stores crash data after an accident, preventing reactivation, or internal hardware errors occur due to overvoltage or aging. Software problems or a communication failure can also necessitate a Chrysler Voyager AS airbag control unit repair.
After the airbags have been deployed, even in minor accidents, the control unit often blocks further deployments and must be reprogrammed or repaired.
Internal component defects can occur due to aging, moisture ingress or power fluctuations, which impairs function.
A failure of the module's internal communication results in the airbag warning light remaining permanently illuminated and the system no longer functioning.
Common error codes for Chrysler Voyager AS airbag control unit repair
For an effective Chrysler Voyager AS airbag control unit repair, knowledge of specific error codes is essential, as these directly indicate problems within the control unit itself. Codes like B1000 or 65535 signal internal defects or communication failures that require detailed diagnosis.
- B1000 → Control unit communication error → Cause: Defective airbag control unit or software problem, loss of communication with the diagnostic device.
- 65535 → Control unit defective → Cause: Internal, serious error in the airbag control unit that requires repair or replacement.
- 93F9 → Internal error in the airbag control unit → Cause: Hardware defect or overvoltage, impairs the internal functionality of the module.
These error codes usually directly indicate a problem with the airbag ECU and require professional diagnosis and Chrysler Voyager AS airbag control unit repair.
Error codes from sensors or belt tensioners are expressly excluded and are considered separately.
What part numbers are available for Chrysler Voyager AS airbag control unit repair?
For a correct Chrysler Voyager AS airbag control unit repair, it is crucial to use the exact OEM part number, as different models and years require specific control units. Verified numbers include both genuine Chrysler/Mopar parts and components from original equipment manufacturers such as Siemens VDO.
Part number 68405565AC is a common original Chrysler/Mopar part number for the Chrysler Voyager airbag control module.
The predecessor or alternative original number is 68405565AB, which is often replaced by the AC version and can also be used for the Chrysler Voyager AS airbag control unit repair.
Another verified Chrysler/Mopar OEM number is 68405567AC, which also identifies the airbag control module in the Chrysler Voyager.
Part number 68480707AC has also been confirmed as the original OEM number for the airbag control unit of the Chrysler Voyager (e.g. model year 2021) and is relevant for the repair.
As an OEM supplier part number from Siemens VDO, 68000020AI is known for airbag control units of the Chrysler Voyager and is used in specialized workshops.
Another Siemens VDO part number is 5WK43858, which was also used as an original supplier component for the airbag control unit in the Chrysler Voyager.
Technical specifications and functionality of the Chrysler Voyager AS airbag control unit
The Chrysler Voyager AS airbag control unit is designed for precise crash detection and multi-stage airbag deployment to ensure maximum occupant safety. It operates on 12 volts of on-board voltage, communicates via CAN bus, and stores important diagnostic data and accident events for further Chrysler Voyager AS airbag control unit repair.
It continuously monitors acceleration sensors and other safety systems to control the optimal response of the restraint systems in the event of an impact.
The control unit can initiate different deployment levels for driver and passenger airbags depending on the intensity and type of impact.
In the event of an accident, comprehensive crash data is saved in the internal memory, which is important for forensic analysis and restoration of operational readiness.
The device's software is flash-capable, allowing updates and recoding to fix system errors or ensure compatibility.
Installation position and important information for Chrysler Voyager AS airbag control unit repair
The central mounting location of the Chrysler Voyager AS airbag control unit, usually under the driver's seat or in the center console, allows for easy access for diagnostics and any necessary Chrysler Voyager AS airbag control unit repairs. Careful handling and attention to the correct connections are essential for proper function.
The module has multi-pin connectors for power supply, data communication and connection to various sensors.
A clean and corrosion-free connector connection is essential for reliable signal transmission and function of the entire system.
Due to its safety-relevant function, the repair or replacement of the airbag control unit may only be carried out by qualified specialist personnel.
After a replacement or repair, the control unit often needs to be adapted to the vehicle coding and programmed with the correct firmware.
