What is a Chrysler LeBaron 1st Gen airbag control module?
The Chrysler LeBaron 1st Gen Airbag Control Unit (ECU) is the central electronic control unit (ECU) responsible for your vehicle's safety systems. It continuously monitors sensors, detects accidents, and deploys the airbags precisely in an emergency. It also stores important crash data and enables the diagnosis of faults throughout the restraint system.
This module, an integral part of the Supplemental Restraint System (SRS), is designed to protect the driver and passengers in the event of a collision. It processes signals from acceleration sensors and collision detectors.
The fast and reliable function of the airbag control unit is crucial for the activation of front and side airbags as well as potentially other passive safety elements.
Why is the Chrysler LeBaron 1st Gen airbag control module defective?
A defective Chrysler LeBaron 1st Gen airbag control unit often occurs due to internal component failures, communication problems with other vehicle systems, or stored crash data after an accident. Because the module can be damaged by age, power surges, or short circuits, system failures can occur, necessitating professional Chrysler LeBaron 1st Gen airbag control unit repair .
Common causes include internal circuit failures that can render the module inoperable. This often results in a permanently illuminated airbag warning light in the dashboard.
Communication problems with the vehicle's network (CAN bus) can also lead to failure, preventing the control unit from sending or receiving data. Corrosion on the connectors can also impair function.
After an accident, the airbag control unit stores crash data and must be reset to become operational again; otherwise, it remains disabled.
Common error codes for Chrysler LeBaron 1st Gen airbag control unit repair
Chrysler LeBaron 1st Gen airbag control unit repair typically involves reading error codes that indicate internal defects or communication issues within the module. These codes signal specific problems within the airbag ECU or its connection to the vehicle, necessitating a precise diagnosis of the faulty system.
- B1000: Control unit communication error → Cause: The airbag control unit cannot communicate properly with the vehicle, often due to wiring problems or internal defects.
- B1014: Airbag control unit communication error → Cause: Similar to B1000, indicates a general loss of communication with the module.
- B1239: Airbag diagnostic sensor unit malfunction → Cause: An internal error in the diagnostic part of the airbag control unit itself.
- B1499: SRS-ECU detects already deployed airbag → Cause: The control unit has stored crash data and is locked, typically after an accident.
- B1620: Internal Error - Control Unit Must Be Replaced → Cause: A serious internal defect that requires replacement or professional repair .
- B0091: SRS control unit configuration error → Cause: Incorrect or corrupted configuration data in the module, often after software problems.
- U0154: Loss of communication with airbag control unit (esp. seat occupancy classification) → Cause: The airbag control unit has lost communication with a connected control unit, such as the one for seat occupancy.
What part numbers are available for the Chrysler LeBaron 1st Gen airbag control unit repair?
There are currently no 100% verified, exact OEM part numbers publicly and independently confirmed for the Chrysler LeBaron 1st Gen airbag control module repair . Sources like MoparPartsGiant list modules for the LeBaron, but don't provide precise, series-accurate numbers for the first generation, making the search for a replacement difficult.
Although major suppliers such as Bosch, Continental and Siemens offer airbag control units, they do not offer specific OEM part numbers for the Chrysler LeBaron 1st Gen model in their publicly accessible catalogs.
This means that the exact OEM part number of the original component cannot be easily found via general databases.
For precise identification during workshop diagnostics, it is recommended to inquire directly with an authorized Chrysler dealer and provide the vehicle identification number (VIN).
Specialized airbag control unit repair services may have internal access to relevant reference numbers that are helpful in the event of a failure or defective module.
Despite the lack of publicly confirmed part numbers, diagnosing and repairing the existing module is often the most practical solution, especially in cases of internal errors or stored crash data.
