2014 Dodge Dart 2.4L Engine Control Module (ECM): Programming, Issues, and Replacement

Symptoms of a Failing 2014 Dodge Dart ECM

A failing ECM can cause a wide range of problems, from a simple check engine light to a car that won't start at all. Because the ECM controls so many different systems, symptoms can sometimes be mistaken for other issues. Diagnosing a bad ECM often involves ruling out other potential causes first.

• Check Engine Light: An illuminated Check Engine Light is one of the most common signs. If the light stays on but the car seems to run fine, the ECM itself could be the problem.
• Engine Stalling or Misfiring: The engine may stall, stutter, misfire, or run roughly. This can be caused by the ECM failing to send correct signals for fuel and spark.
• Car Will Not Start: The engine may crank but refuse to start. This can happen if the ECM does not send the proper signals to the fuel injectors or ignition coils.
• Poor Performance and Fuel Economy: A noticeable drop in gas mileage or a feeling that the car is sluggish and lacks power can point to an ECM issue.
• Transmission Shifting Problems: On automatic transmission models, a bad ECM can cause rough, erratic, or delayed shifting because it fails to send the correct data to the Transmission Control Module (TCM).
• Flashing Odometer: After an incorrect ECM is installed, the odometer will often flash continuously. This indicates a "proxy alignment" is needed to sync the new module with the vehicle's other computers.

Common Diagnostic Trouble Codes (DTCs)

While many codes can indicate an ECM-related issue, codes in the P0600-P0699 range specifically relate to the computer and its output circuits. Manufacturer-specific codes like P1389 (No ASD Relay Output Voltage at PCM) or P1391 (Intermittent Loss of CMP or CKP) can also point directly to a module or wiring problem.

Known Issues, TSBs, and Recalls

While there are no specific recalls for the Engine Control Module on the 2014 Dodge Dart, there are related items of note.

• TSB 18-023-16: This Technical Service Bulletin involves reprogramming the Powertrain Control Module (PCM) for 2.4L engines with updated software to address certain diagnostic and system improvements. If you are experiencing issues, ensuring your vehicle's software is up to date is a good first step.
• Transmission Control Module (TCM) Recall (15V542000 / R42): Many 2013-2015 Darts were recalled for a faulty TCM that could cause the transmission to unexpectedly shift into neutral. It is important to distinguish these transmission-specific symptoms from a broader ECM failure.
• Brake Booster Recall (15V800000): Some 2013-2014 Darts with the 2.0L and 2.4L engines were recalled because oil could seep into the brake booster, reducing power brake assist.

Buying a Used Engine Control Module (ECM)

Purchasing a used OEM ECM is a cost-effective solution, but careful verification is required to ensure it will work with your vehicle. A used module that has been properly tested and programmed can be just as reliable as a new one.

1. Verify Compatibility by Part Number

This is the most critical step. You must match the OEM part number from your original module exactly. Several part numbers were used for the 2014 Dart 2.4L, and they are often superseded. Do not rely on visual appearance alone.

• Start by finding the part number on your car's original ECM.
• Match this number to the replacement part. The initial numbers must match; the letters at the end often indicate software revisions and may differ.
• Verified part numbers for the 2014 Dart 2.4L include: 05150946AA, 05150946AB, 5190916AA, 5190916AB, 5190916AC, 68205427AM, and 68205428AB.

2. Programming is NOT Optional

A replacement ECM for a 2014 Dodge Dart must be programmed to your vehicle's specific Vehicle Identification Number (VIN). It is also linked to the car's anti-theft system (immobilizer). The vehicle will not start and run correctly until this is done. Do not trust sellers who claim the module is "plug and play" without VIN programming.

3. Who Can Program the ECM?

• Dealer: A Chrysler/Dodge dealer can always program a new or used ECM using their proprietary wiTECH diagnostic software. 🎬 Watch: How to run a proxi alignment using wiTECH However, some dealers may refuse to program a used part they did not sell.
• Specialized Independent Shops: Many independent auto repair shops that specialize in electronics have the tools (like an Autel scanner or J2534 pass-through device) to perform module programming.
• Mobile Locksmiths/Programmers: Some automotive locksmiths offer mobile module programming services and can perform the necessary procedures on-site.
• Mail-In Programming Services: Many online vendors sell used ECMs that are pre-programmed to your VIN before shipping. You provide your VIN when ordering, and they flash the module so it is ready for installation. For some systems, a final key relearn or proxy alignment may still be needed on the vehicle.

4. Physical Inspection

When your used part arrives, inspect it carefully. Check for corrosion on the connector pins, cracks in the casing, or any signs that the module has been opened or exposed to water. A clean, undamaged module is crucial for long-term reliability.
