What is a Chrysler Laser AA airbag control unit?
The Chrysler Laser AA airbag control unit is the central safety unit in your vehicle, activating all occupant restraint systems in the event of an accident. It continuously monitors a multitude of sensors, stores relevant crash data, and ensures precise deployment of the airbag modules and seatbelt pretensioners to maximize occupant safety.
This electronic module is critical to the passive safety of the Chrysler Laser AA. It receives signals from acceleration sensors and crash sensors throughout the vehicle.
Based on this data, the control unit makes a decision within milliseconds about whether to trigger the protective systems. It also performs continuous self-tests to verify system readiness.
Why is the Chrysler Laser AA airbag control unit defective?
A defective Chrysler Laser AA airbag control module can often be caused by stored crash data after an accident, internal electronic faults, or power supply issues. Because it permanently stores crash information after an impact, the module typically needs to be repaired or replaced to restore the airbag system to normal operation.
Common causes of failure include internal short circuits or moisture damage. Overvoltages in the vehicle electrical system can also affect the sensitive electronics.
Another common error is storing crash data after an impact, even in minor accidents. This causes the airbag system to permanently report a malfunction and be disabled until the control module is reset or the Chrysler Laser AA airbag control module repair is performed.
Communication errors with other vehicle modules can sometimes also cause the error message. A precise diagnosis is essential to determine the cause of the defect.
Common error codes for Chrysler Laser AA airbag control unit repair
When diagnosing a faulty Chrysler Laser AA airbag control module, specific error codes will appear that indicate communication problems, open circuits, or internal module defects. These codes help identify the exact cause of the failure and direct the repair.
- **B1000** → Control unit communication error → Internal problem of the airbag ECU or disturbed bus communication.
- **B1C27-13** → Left Thorax Squib 1 Circuit Open → Open circuit in the circuit of the left seat airbag, controlled by the airbag control unit.
- **U0154** → Communication loss with Occupant Classification Module → Problem in the data connection between the airbag ECU and the occupant classification module.
- **B0020-13** → Left Airbag Deploy Squib Circuit Error → Malfunction in the left front airbag deployment circuit, directly monitored by the airbag ECU.
- **B0028-13** → Right Airbag Deploy Squib Circuit Error → Error in the right front airbag deployment circuit caused by the airbag controller.
- **FC 1** → Control unit defective / no communication → Generalized failure of the airbag control unit, often after a crash or in the event of an internal hardware defect.
What part numbers are available for Chrysler Laser AA airbag control unit repair?
There are no exact, publicly verified OEM part numbers for the Chrysler Laser AA airbag control module, making direct parts sourcing difficult. To obtain the correct part number for your vehicle, a direct inquiry to an authorized Chrysler Parts Center or repair shop with your vehicle identification number (VIN) is essential.
Specialized parts catalogs and databases do not list specific airbag control units specifically for the Chrysler Laser AA. Even common suppliers such as Bosch and Continental do not list this number in their general catalogs for this model.
Finding a precise OEM number for the Chrysler Laser AA airbag control unit repair requires access to professional databases with VIN queries or direct contact with the manufacturer. This ensures that you find the right module for your vehicle.
Although examples of airbag control units from other Chrysler models exist, these are not transferable to the Laser AA. A mix-up could lead to serious safety issues and compromise the successful repair.
