What is a Chrysler LeBaron K airbag control module?
The Chrysler LeBaron K airbag control unit is the central safety unit of the occupant protection system (SRS), which activates all restraint systems in the event of an accident. It continuously monitors sensors, stores important crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle to ensure maximum safety.
This module, often referred to as the airbag diagnostic module, is crucial for vehicle safety. It processes signals from impact sensors. In the event of a collision, the control unit triggers pyrotechnic airbags and seatbelt pretensioners.
In addition to the trigger function, the control unit continuously monitors the system status. Errors are detected and stored in the internal memory. The airbag warning light in the dashboard signals malfunctions or an accident.
Why is the Chrysler LeBaron K airbag control unit defective?
A defective Chrysler LeBaron K airbag control unit is often the result of an accident, as crash data is stored in the module, preventing the system from reactivating. Other causes can include age-related material fatigue, electrical short circuits, or moisture damage, which can damage the internal circuitry and necessitate a Chrysler LeBaron K airbag control unit repair.
After an accident, the control unit stores indelible crash data. This data locks the system, requiring a reset or replacement after the vehicle damage has been repaired. Without this reset, the airbag warning light remains active.
Even without an accident, the airbag control unit in the Chrysler LeBaron K can fail. Common causes include corrosion on the connectors or internal component failure. This then leads to a malfunction of the entire SRS system.
Regular diagnostics can help detect impending failures early. If signs of failure occur, you should immediately visit a specialist workshop for a Chrysler LeBaron K airbag control unit repair.
Common error codes for Chrysler LeBaron K airbag control unit repair
While there are no specific trouble codes unique to the Chrysler LeBaron K airbag control module, generic Chrysler B codes often indicate problems that require Chrysler LeBaron K airbag control module repair. These trouble codes often relate to the control module's communication or the airbag squib circuitry.
Diagnosis is typically performed using a Chrysler-compatible diagnostic tool. This reads the error codes stored in the airbag control unit. The displayed codes provide information about the type of malfunction.
The most common error codes that may indicate a defective airbag control unit are generally general in nature. They indicate problems within the airbag system.
- **B1000**: This code indicates an internal control unit communication error or malfunction. It indicates a problem directly within the airbag ECU.
- **B1B02**: This trouble code indicates a circuit short or open on the driver airbag squib 1. It affects the driver airbag deployment circuit.
- **B1B06**: This code indicates a signal error on the driver airbag Squib 2 Circuit Low. The airbag control unit is registering an implausible voltage.
- **B1B11**: This code indicates a malfunction of the passenger airbag squib 1 circuit. It is a critical fault in the passenger airbag system.
What part numbers are available for the Chrysler LeBaron K airbag control unit repair?
For the Chrysler LeBaron K airbag control unit repair, two original OEM part numbers from Mopar are primarily verified: 4723293 and DH67LAZ. These were researched exclusively for the 1992-1994 Chrysler LeBaron K model and validated by independent, trusted OEM catalogs to ensure a precise fit.
Part number 4723293 identifies the classic airbag diagnostic and control module. It is the frequently referenced module for LeBaron K variants such as the LX, LE, Base, and Landau from 1992-1994.
Part number DH67LAZ is another original airbag module. It is specifically labeled "Air Bag Module (Sport)" and is also listed in the Mopar OEM catalog for the same model series.
No alternative OEM part numbers from other manufacturers such as Bosch or Continental were found. This suggests that Chrysler/Mopar uses its own specific OEM numbers for these models.
A thorough Vehicle Identification Number (VIN) verification through official Mopar databases is always recommended. This ensures the correct part number is selected for the required Chrysler LeBaron K airbag control unit repair.
