What is a Dodge Charger 4th Gen airbag control module?
The Dodge Charger 4th Gen airbag control unit is the central safety unit for your vehicle, controlling the airbag systems. It continuously monitors sensors in the car, stores important crash data, and ensures the correct and timely deployment of all occupant restraint systems in the event of an accident—essential for your safety.
This module, also known as the SRS (Supplemental Restraint System) module, is the intelligent interface between the impact sensors and the airbags. It is crucial to the functionality of your entire safety system.
A professional Dodge Charger 4th Gen airbag control module repair is often necessary when this critical component shows signs of failure to restore vehicle safety.
Why is the Dodge Charger 4th Gen airbag control module defective?
A Dodge Charger 4th Gen airbag control unit can fail because it stores crash data after an accident and then locks up, resulting in deactivation. Power surges, water damage, or internal hardware failures due to aging can also cause failure, causing the safety systems to no longer function properly.
After an airbag deployment, the control unit is usually locked out of service and must be repaired or replaced. A reset service can often restore the module, provided there is no physical damage.
Water ingress into the vehicle interior or short circuits can cause irreversible damage to the sensitive electronics. This inevitably leads to the need for a Dodge Charger 4th Gen airbag control unit repair.
Internal component defects caused by material fatigue or manufacturing defects can also cause failure. A precise diagnosis in the workshop is essential to determine the exact cause.
Common error codes for Dodge Charger 4th Gen airbag control unit repair
During a Dodge Charger 4th Gen airbag control module repair, specific error codes will occur that directly indicate problems with the control module itself. These range from internal memory errors to communication issues with other vehicle systems, allowing for precise diagnosis and repair of the defect.
The error messages are crucial for a precise diagnosis of the airbag system.
- B1000 → Control unit communication error → Signal interruption or internal defect in the airbag ECU.
- B1001 → Airbag control unit power supply error → Insufficient voltage or short circuit on the power supply.
- B1002 → Internal memory error in the control unit → Defect in the internal memory unit of the module.
- B1003 → EEPROM memory error → Damage to the non-volatile memory, often after a crash event.
- B1015 → Airbag deployment system error → Problem with the internal deployment logic or circuit.
- B1040 → Communication error to crash sensors → Malfunction in the data transmission between the control unit and sensors.
- B1060 → Occupant Classification System Error → Passenger detection malfunction, reported directly by the control unit.
- B1300 → Internal self-test error of the control unit → The module fails its own functional test.
- B1400 → Power supply interrupted → Temporary or permanent loss of power to the module.
- B1500 → Short circuit in the airbag control unit → Internal short circuit in the control unit hardware.
These error codes indicate that repair or replacement of the control unit is essential. A specialized diagnostic tool is always required for a precise error analysis.

Dodge Charger 4th Gen Airbag Control Unit Technical Specifications and Functionality
The Dodge Charger 4th Gen Airbag Control Unit is specifically designed for comprehensive control of all passive safety systems, from airbags to seatbelt pretensioners. It communicates via the vehicle's CAN bus, precisely analyzes sensor data, and instantly deploys the appropriate restraint systems in the event of a collision, maximizing occupant safety.
This module serves as the command center for the entire Supplemental Restraint System (SRS). It integrates data from various crash and occupancy sensors to ensure appropriate deployment.
Continuous monitoring of the system for errors is a core function. Any deviations are stored as error codes and can be read by a workshop, enabling efficient diagnostics.
After an accident, the control unit stores important event data. This information is crucial for reconstructing the accident and subsequently repairing or replacing the Dodge Charger 4th Gen airbag control unit.
Installation location and connections of the Dodge Charger 4th Gen airbag control unit
The Dodge Charger 4th Gen airbag control unit is strategically located centrally in the vehicle, typically under the center console or center console, to ensure short and reliable connections to all sensors and airbags. It features robust, multi-pin connectors for power, the data bus, and all components to be controlled.
The central positioning minimizes electromagnetic interference and ensures fast signal transmission. This is crucial for millisecond response times in an emergency.
The connections include lines for the power supply, the CAN bus for communication with other control units, as well as dedicated inputs for sensors and outputs to the igniters of the airbags and belt pretensioners.
The connectors are designed to be vibration and corrosion resistant over the long term. Improper disassembly or assembly can lead to malfunctions and often require re-diagnosis.
Special features and the importance of programming in the Dodge Charger 4th Gen airbag control unit repair
A key feature of the Dodge Charger 4th Gen airbag control unit is its vehicle-specific programming, often linked to the VIN. A simple replacement without subsequent recoding usually results in error messages, which is why professional programming or a specialized reset service is essential for a successful Dodge Charger 4th Gen airbag control unit repair.
After an accident, a triggered control unit can often be restored to working order through a special reset service, provided there is no physical damage. This is a cost-effective alternative to purchasing a new one.
Different Dodge Charger models (e.g., SRT Hellcat, Police versions) may require slightly different module variants. The part number provides precise information about compatibility.
The control unit works closely with the Occupant Classification System (OCS). This ensures that airbags only deploy when a seat is occupied, preventing unnecessary deployments and the associated costs.
Correct programming after a Dodge Charger 4th Gen airbag control unit repair ensures that all vehicle safety functions are optimally coordinated and no error messages are displayed.
