What is a Chrysler Spirit AA airbag control unit?
The Chrysler Spirit AA airbag control unit is the heart of the occupant protection system and reliably activates airbags and seatbelt pretensioners in the event of a collision. It continuously monitors sensor data, stores important crash information, and thus ensures the safety-relevant function of the restraint systems in Chrysler Spirit AA vehicles.
This safety-related electronic control unit is used in Chrysler Corporation vehicles on the AA platform, particularly the Chrysler Spirit (1989-1995).
It is responsible for the central control and deployment of the airbag systems in the event of an impact. The control unit contains integrated sensors for crash detection and a processing unit for rapid data evaluation.
It is also networked with other vehicle units to trigger precise actions in an emergency. This ensures the best possible protection for the occupants.
Why is the Chrysler Spirit AA airbag control unit defective?
A Chrysler Spirit AA airbag control unit can fail due to internal component failure, age-related wear, or after an impact that stores crash data and disables the system. A Chrysler Spirit AA airbag control unit repair is then essential, as the control unit no longer functions properly and the airbag warning light remains permanently illuminated, compromising vehicle safety.
If the control unit has an internal fault or its communication capability is limited, the airbag warning light may illuminate.
This signals a critical failure in the vehicle's safety system. Such defects require immediate diagnosis and repair.
A repair or reset of the control unit is often necessary to restore functionality after an airbag deployment.
A precise diagnosis is essential to identify the cause of the fault and ensure vehicle safety. A professional workshop can help with this.
Common error codes for Chrysler Spirit AA airbag control unit repair
Chrysler Spirit AA airbag control unit repairs often involve specific error codes that indicate internal problems with the control unit or communication problems within the vehicle. These codes, such as B1000 or U0171, directly indicate defects in the airbag control unit and are crucial for accurate diagnosis and subsequent repair.
- B1000 → Communication error in the airbag control unit → Insufficient or disrupted data transmission within the control unit or to the CAN bus.
- B1B02 → Airbag control unit internal error → Defective internal components or faulty logic in the control unit itself.
- B1B06 → Airbag control unit memory error → Problems with the non-volatile memory, often after a crash that requires a reset.
- U0171 → Loss of communication with airbag control unit → Interruption of the data connection between the control unit and other vehicle systems, often a bus error.
What part numbers are available for the Chrysler Spirit AA airbag control unit repair?
For Chrysler Spirit AA airbag control unit repairs, exact OEM part numbers are not publicly available or clearly verifiable, as they are often VIN-specific for security reasons and are rarely publicly published. Precise identification of the required control unit therefore always requires a VIN-based query from an authorized Chrysler/Mopar dealer.
The original part numbers for airbag control units are rarely publicly disclosed for safety and recall reasons. Parts identification is usually done through authorized dealers or OEM parts catalogs by entering the VIN.
The Chrysler Spirit is based on the AA body platform, which is also used by the Dodge Spirit, Plymouth Acclaim, and Chrysler Saratoga. Despite this similarity, ACU part numbers are not clearly assignable without a VIN-specific detail query.
We recommend using official Chrysler/Mopar OEM parts catalogs with VIN lookup or contacting Mopar dealers directly. This is the most reliable way to obtain the exact OEM part number for your Chrysler Spirit AA airbag control module and complete a successful repair.
