What is a Dodge Challenger LC airbag control module?
The Dodge Challenger LC airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle, which is of utmost importance for safety.
This module, also known as the Occupant Restraint Controller (ORC) or Supplemental Restraint System (SRS) Control Module, is the brain of your passive safety system. It receives signals from impact sensors and decides in milliseconds whether to deploy airbags and seatbelt pretensioners.
The airbag control unit for the Dodge Challenger LC is typically located under the center console. It is protected there and connected to the vehicle's network via several connectors.
Why is the Dodge Challenger LC airbag control unit defective?
A Dodge Challenger LC airbag control unit can fail because it is storing crash data after an accident, experiencing internal hardware failures, or being damaged by power surges. Water damage or faulty communication within the vehicle's network are also common causes of failure that require a Dodge Challenger LC airbag control unit repair.
The module often permanently stores so-called "crash data" after an airbag deployment, which prevents its further use. Internal errors in the EEPROM memory or firmware can also impair functionality.
Power supply issues or incorrect coding after a replacement also frequently lead to malfunctions. Such defects are usually signaled by the illuminated airbag warning light.
Common error codes for Dodge Challenger LC airbag control unit repair
During Dodge Challenger LC airbag control module repair, specific error codes may occur, indicating internal defects or communication issues within the module. These codes are crucial for identifying the exact cause of the malfunction and enabling targeted repair of the airbag system.
These B-codes indicate problems with the control unit itself, not with sensors or other peripherals. Diagnostics with a suitable OBD-II scanner are essential for troubleshooting.
- B1000 → Control unit communication error → Internal defect or disrupted bus communication.
- B1001 → Internal control unit error → Defect within the module hardware or software.
- B1010 → Airbag module power supply → Problem with the power supply to the control unit.
- B1013 → EEPROM memory error in the control unit → Corrupt or damaged data in the internal memory.
- B1020 → Airbag control unit firmware error → Software error in the module operating system.
- B1100 → Control unit initialization error → Module does not start correctly or does not perform self-test.
- B1120 → Interface error to other control units → Communication fault with other vehicle systems.
- B1170 → Missing or faulty data in the airbag module → Incomplete or inconsistent module data.
- B1180 → Airbag module memory overflow or memory error → Internal memory capacity problems.
- B1338 → Control unit coding / VIN matching error → Incorrect programming or VIN discrepancy.
- B1345 → Hardware defect in the control unit → Physical damage or failure of an internal component.
What part numbers are available for Dodge Challenger LC airbag control unit repair?
For Dodge Challenger LC airbag control module repair, there are several OEM part numbers and official replacement numbers that ensure compatibility with your vehicle. These numbers are crucial for identifying the correct control module and performing a smooth replacement or reset.
The main number for many models is 68367992AA. This number has been verified multiple times by trusted sources and is widely used.
There are also other original OEM numbers such as 68316747AB and 68371751AA that are also relevant. These cover different model years or equipment variants.
There are also official Mopar superseded replacement numbers that serve as equivalent replacements. These include 68316749AB, 68316749AA, 68256826AB, 68256826AC, 68316748AB, 68204700AD, 68297882AA, and 68204700AF.
Technical specifications and compatibility for Dodge Challenger LC airbag control unit repair
The Dodge Challenger LC airbag control unit is a highly complex unit specifically designed for occupant safety and subject to strict specifications. It is compatible with Challenger LC models from approximately 2015 onward and controls all airbags and seatbelt pretensioners for optimal protection.
This module operates on the vehicle's battery and is protected by two 10-amp fuses. When the vehicle is started, it performs a self-test, during which the airbag warning light flashes briefly.
Compatibility is given for Dodge Challenger LC models, especially those built between 2015 and 2019, but often also until 2023. It is independent of the engine such as 3.6L V6 or 6.2L HEMI V8 SRT Hellcat.
Installation is typically done under the center console, near the transmission tunnel. All connectors are precisely designed for a secure electrical connection.
How does the Dodge Challenger LC airbag control unit repair work?
Dodge Challenger LC airbag control unit repair typically involves resetting the module after an accident to erase stored crash data and restore the control unit to full functionality. This is a cost-effective alternative to purchasing a new one and restores the safety system to full operational readiness.
Specialized workshops can read the control unit, remove crash data, and restore it to its factory state. In most cases, the module is then plug-and-play and does not require reprogramming.
Before performing any work on the airbag system, disconnect the vehicle's battery and wait at least three minutes. This prevents accidental deployment of the airbags or seatbelt pretensioners during the Dodge Challenger LC airbag control unit repair.
After successful repair and installation, the airbag warning light in the dashboard should go out. For persistent problems, further diagnostics are necessary.
