2014 Dodge Dart Body Control Module: Solving Electrical Gremlins and Programming Puzzles
This guide covers the common failure symptoms, mandatory programming requirements, and how to choose the right used Body Control Module for your 2014 Dodge Dart.
- A replacement BCM for a 2014 Dodge Dart MUST be programmed to the vehicle using a procedure called a 'Proxy Alignment'.
- A flashing odometer is the most common symptom indicating that a proxy alignment is needed.
- When buying a used BCM, you must match the OEM part number exactly (e.g., 68210721AA or 68245834AA).
- Many widespread electrical problems can be caused by a failing BCM, but always check battery health and ground connections first.
Symptoms of a Failing Body Control Module
A bad BCM in a 2014 Dodge Dart can create a host of frustrating electrical issues. Because the BCM controls so many different components, symptoms can be widespread and appear random. Often, a weak or failing battery can cause similar issues, so it's important to test the battery and charging system before condemning the BCM.
- Flashing Odometer: This is a classic sign on many Chrysler/Dodge vehicles that a module is not communicating correctly with the rest of the car's network. It indicates that a "proxy alignment" is needed.
- Erratic Electronics: You might experience power windows that don't work, door locks that act on their own, or interior/exterior lights that flicker or fail to turn on or off.
- Instrument Cluster Malfunctions: Gauges may behave erratically, or multiple warning lights (like for the ABS or airbag system) may illuminate for no apparent reason.
- No-Start or Stalling: In some cases, a failing BCM can interfere with the vehicle's anti-theft system or other critical functions, preventing the car from starting or causing it to stall unexpectedly.
- Persistent Battery Drain: A faulty BCM might not go into "sleep mode" properly when the car is off, causing a slow drain on the battery that can leave you stranded.
- Communication Codes: A professional scan tool may reveal U-series (communication) or B-series (body) trouble codes. A common code pointing to a BCM communication failure is U0140.
Known Issues, TSBs, and Recalls
While there are no widespread recalls specifically for the BCM itself on the 2014 Dodge Dart, there are related service bulletins and recalls for electrical and module-related issues.
- Safety Recall P76 / NHTSA 14V-800: This recall was issued for a small number of 2015 model year Darts (built in late 2014) where the BCM was incorrectly configured for the Tire Pressure Monitoring System (TPMS). The fix was to reconfigure, not replace, the BCM.
- General Electrical Problems: Many owners report a variety of electrical issues that can sometimes be traced back to poor grounds rather than a failed BCM. Before replacing the module, it's wise to check and clean the main battery and chassis ground connections. 🎬 Watch: How to fix electrical gremlins with a ground upgrade.
- Other Module Recalls: The 2014 Dart had recalls for the Transmission Control Module (TCM) which could cause the vehicle to shift into neutral unexpectedly. It's important to distinguish these symptoms from a BCM failure.
Important: A flashing odometer is a definitive sign that a module has been replaced or has lost its configuration and requires a procedure called a Proxy Alignment.
Programming and Calibration Requirements
A replacement Body Control Module in a 2014 Dodge Dart absolutely requires programming to function correctly. You cannot simply swap a used module from another vehicle and expect it to work. The vehicle's computer network will detect the mismatched module, leading to a flashing odometer and malfunctioning features.
The required procedure is called a "Proxy Alignment." This process syncs the new BCM with all the other control modules in the vehicle (like the engine computer, transmission computer, and instrument cluster), essentially introducing it to the car's network.
Who Can Program the BCM?
- Dealerships: A Dodge/Chrysler dealership can perform a proxy alignment using their proprietary wiTECH diagnostic tool.
- Independent Shops: Many independent repair shops with advanced diagnostic tools (like high-end Autel or Snap-on scanners) can perform a proxy alignment.
- Advanced DIY/Enthusiasts: It is possible for individuals to perform a proxy alignment using software called AlfaOBD paired with a compatible OBD-II interface like the OBDLink MX+. 🎬 See how to perform a DIY proxy alignment using AlfaOBD. This is a popular option in the Dart community for those who are comfortable with computer diagnostics.
Buying a Used Body Control Module
Purchasing a used OEM BCM is a cost-effective way to fix your Dart's electrical problems. Since these modules are primarily software-driven and have no moving parts, a used unit from a reputable source is often just as reliable as a new one once programmed.
What to Look For:
- Match the Part Number Exactly: The most critical step is to match the OEM part number on your original BCM with the one you are purchasing. The primary verified part numbers are 68210721AA and its replacement, 68245834AA. Using a module with a different part number may result in incompatibility, even if it looks identical.
- Inspect for Damage: The BCM is located inside the passenger cabin, under the driver's side of the dashboard, making it less susceptible to environmental damage. However, always inspect the replacement unit for any signs of physical damage, bent pins, or corrosion on the connectors, which could indicate water intrusion from a windshield leak.
- Source from a Reputable Supplier: Buy from a seller that offers a warranty and has a good return policy. This protects you in case you receive a defective part.
Pro Tip: Some specialized services offer to "clone" your original BCM. This involves transferring all the data (including VIN and configuration) from your old module to the replacement used module. A cloned module is often plug-and-play and may not require a proxy alignment, potentially saving you a trip to the shop.
Cost Comparison
The cost of replacing a BCM can vary significantly based on the part source and labor rates. Programming is a required additional cost.
| Item | Estimated Cost |
|---|---|
| New OEM (Mopar) | $250 - $370 |
| Used OEM | $50 - $150 |
| Remanufactured | $200 - $400 |
| Shop Labor (Installation) | $100 - $200 |
| Shop Labor (Programming/Proxy Alignment) | $100 - $250 |
Frequently Asked Questions (FAQ)
Where is the BCM located on a 2014 Dodge Dart?
The Body Control Module is located inside the car, under the dashboard on the driver's side, behind a trim panel. Accessing it requires removing the lower dash cover.
🎬 Watch this video to see the BCM location and replacement.Do I have to take my car to the dealer to program a new BCM?
No, a dealership is not the only option. Many well-equipped independent shops can perform the required "proxy alignment." Additionally, DIY-savvy owners can perform the procedure themselves using software like AlfaOBD and a compatible OBD-II adapter.
Will a bad BCM cause a check engine light?
Usually, no. The check engine light is typically controlled by the Powertrain Control Module (PCM) for engine and emissions-related faults. A bad BCM is more likely to cause body-related codes (B-codes), communication codes (U-codes), or illuminate other warning lights like the ABS or airbag indicators.
Can I fix a BCM myself?
Repairing a BCM is generally not a DIY task. They are complex circuit boards, and failures are often due to internal component issues. The standard repair is to replace the module and have the new one programmed to the vehicle.
