What is a Chrysler Town & Country airbag control module?
The Chrysler Town & Country airbag control unit, also known as the occupant restraint controller (ORC), is your vehicle's central safety unit, precisely activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of a collision. It continuously monitors crash sensors and stores relevant accident and fault data, ensuring the proper function and safety of the entire airbag system.
This module is crucial for passive safety and controls the pyrotechnic ignition circuits within milliseconds of an accident being detected.
In the event of a malfunction or after the airbag system has deployed, the airbag warning light will be activated to indicate that service or repair is necessary.
Why is the Chrysler Town & Country AS airbag control unit defective?
A Chrysler Town & Country AS airbag control unit can fail for a variety of reasons, often following an accident, due to internal hardware or software errors, power surges, moisture damage, or age-related wear and tear, which impairs the proper functioning of the safety components and necessitates professional repair. If the control unit no longer communicates or stores error messages, this indicates a failure.
Typical signs of failure include a permanently illuminated airbag warning light or specific error codes that indicate internal problems with the module.
After an impact, the control unit stores crash data and must be reset or replaced to become fully functional again and ensure the safety of the vehicle.
Common error codes for Chrysler Town & Country AS airbag control unit repair
When diagnosing a faulty Chrysler Town & Country AS airbag control module, repair shops often encounter specific B-codes that directly indicate internal module problems or communication errors. These codes are crucial for identifying the exact failure and initiating a targeted repair, as they signal that the control module itself is affected, not just peripheral sensors.
- B1000 → Control unit communication error → Cause: Problem in the data transmission between the airbag ECU and other vehicle systems.
- B1100 → Airbag control unit internal error → Cause: Internal hardware or software defect within the airbag ECU.
- B1105 → Airbag control unit internal memory error → Cause: Damage or corruption of the internal memory in the airbag ECU.
- B1201 → Airbag control unit power supply error → Cause: Insufficient or unstable power supply to the airbag ECU.
- B1205 → Control unit EEPROM memory error → Cause: Error reading or writing the EEPROM memory in the airbag ECU.
- B1300 → Internal control unit reset/restart error → Cause: Unexpected reset or restart of the airbag ECU, often due to internal malfunctions.
What part numbers are available for Chrysler Town & Country AS airbag control unit repair?

The Importance of Chrysler Town & Country AS Airbag Control Unit Repair
A timely Chrysler Town & Country AS airbag control unit repair is of utmost importance, as the module plays a pivotal role in occupant safety by deploying the airbags and seatbelt pretensioners in an emergency. A defective control unit compromises the vehicle's overall passive safety and can have life-threatening consequences in an emergency, so professional diagnosis and repair are essential.
In addition to safety, a functioning airbag unit is also a prerequisite for a valid general inspection (TÜV).
A reset service often enables a cost-effective restoration of functionality without having to purchase an expensive new part and is an important part of the repair.
Function and installation position of the airbag control unit
The airbag control unit in the Chrysler Town & Country continuously receives signals from peripheral crash sensors and triggers pyrotechnic ignition circuits for airbags and seatbelt pretensioners within milliseconds in the event of an accident, providing optimal occupant protection. Repairing or replacing it requires precision and expertise due to its central role in the safety concept.
The module is usually located centrally in the interior, often under the center console or the driver's seat, to ensure short distances to all relevant sensors and actuators.
The connection to the vehicle's OBD system enables the diagnosis of errors and the activation of the airbag warning light in the event of problems.
