What is a Chrysler Neon SX airbag control unit?
The Chrysler Neon SX airbag control unit is the central safety unit in your vehicle, continuously monitoring sensor data. It processes this information in real time to precisely and instantly activate the airbags and seatbelt pretensioners in the event of an accident, thus significantly ensuring occupant safety.
This safety-critical component is responsible for the precise coordination of all passive safety systems on board the Chrysler Neon SX and Dodge Neon. It also stores important crash and diagnostic data.
Proper function is essential for occupant protection and is monitored through regular system self-tests. If errors occur, a "Chrysler Neon SX airbag control unit repair" is often necessary.
Why is the Chrysler Neon SX airbag control unit defective?
A Chrysler Neon SX airbag control unit can fail due to internal components aging over time, electrical surges, or accident events storing "crash data" in the module. Such defects prevent the airbag system from functioning properly, requiring immediate "Chrysler Neon SX airbag control unit repair."
Common causes of failure include internal memory errors, damage caused by moisture or corrosion, and incompatible software updates. This often leads to the airbag warning light in the cockpit remaining permanently illuminated.
Even after a minor impact, the control unit often stores so-called crash data that prevents further airbag deployment. In these cases, the control unit must be reset or a professional "Chrysler Neon SX airbag control unit repair" must be performed.
Common error codes for Chrysler Neon SX airbag control unit repair
When diagnosing a faulty Chrysler Neon SX airbag control unit, common B-codes often occur. These indicate communication problems, internal memory errors, or processing errors within the control unit itself. A precise "Chrysler Neon SX airbag control unit repair" requires a precise reading of these codes.
- B1000 → Control unit communication error → Airbag ECU
- B1001 → Airbag control unit not found / no communication → Airbag ECU
- B1002 → Internal memory error in the airbag control unit → Airbag ECU
- B1010 → Internal diagnostic error in the control unit → Airbag ECU
- B1100 → Processing error in the control unit → Airbag ECU
- FC1 → Control unit defective / no communication → Airbag ECU
For a precise fault diagnosis, we recommend using professional Chrysler diagnostic tools, as these provide deeper insight into manufacturer-specific error codes. Only then can the exact cause of the failure be identified.
What part numbers are available for Chrysler Neon SX airbag control unit repair?
The only verified and genuine OEM part number for the airbag control module in the Chrysler Neon SX and Dodge Neon is P04671774AC from Mopar. This exact number is crucial for a successful Chrysler Neon SX airbag control module repair and ensures full compatibility and safety standards.
Part number P04671774AC has been confirmed on specialized airbag module platforms as being suitable for the Dodge Neon (equivalent to the Chrysler Neon SX) from approximately 2000-2003. It is important to precisely match the defective module to this number.
Other part numbers available on the market often refer to sensors, airbag inflators, or other steering wheel components, but not to the central control unit. Only this specific OEM number is relevant for restoring functionality.
Technical details and compatibility for the Chrysler Neon SX airbag control unit repair
The Chrysler Neon SX airbag control unit is specifically designed for 12-volt electrical systems and processes signals from crash sensors to instantly activate airbags and seatbelt pretensioners. It is primarily compatible with Chrysler Neon I (1994-1999) and Neon II (approx. 2002) models, including the Neon SX with 1.6L and 2.0L engines.
This microcontroller-based module performs self-diagnosis during ignition and detects internal or external errors in the airbag system. It is installed centrally in the vehicle, usually under the dashboard.
After a successful "Chrysler Neon SX airbag control unit repair," the module typically receives a one- to three-year warranty because it is a safety-critical component. Proper reprogramming and calibration after installation is essential.
Installation position and connections of the Chrysler Neon SX airbag control unit
The Chrysler Neon SX's airbag control unit is typically located centrally in the vehicle, often under the dashboard or in the center console, to ensure short signal paths. It has dedicated connections for power, various crash and seat occupancy sensors, and outputs to airbags and seatbelt pretensioners.
The main power supply is 12 volts, and data communication takes place via the OBD-II interface for vehicle diagnostics. Properly seated and locked connectors are essential for proper function.
When replacing or repairing the Chrysler Neon SX airbag control unit, meticulous care is required. It is important to ensure that all connections are made correctly to avoid malfunctions in the sensitive safety system.
