2015-2016 Dodge Dart 1.4L Turbo ECM: Programming, Failure Codes, and Replacement Guide

Symptoms of a Failing ECM

A failing Engine Control Module in a 2015-2016 Dodge Dart can cause a wide range of problems, from minor annoyances to a complete no-start condition. Because the ECM controls so many systems, symptoms can often be mistaken for other issues.

• Check Engine Light: This is the most common symptom. Specific trouble codes pointing to internal module failure are a strong indicator.
• Engine Performance Issues: You might experience random stalling, rough idling, engine misfires, poor acceleration, or a sudden loss of power.
• No-Start Condition: The engine may crank but refuse to start if the ECM is not properly controlling the fuel and spark.

• Poor Fuel Economy: If the ECM cannot correctly calculate the air-fuel mixture, fuel consumption can increase significantly.
• Communication Errors: Other modules in the vehicle may lose communication with the ECM, leading to various warning lights on the dashboard.

Common Diagnostic Trouble Codes (DTCs)

While many codes can be related to a faulty ECM, some are more direct indicators than others:

• P0601 - Internal Control Module Memory Checksum Error: This code is a definitive sign of an internal ECM failure. It means the module's self-check has failed, indicating corrupted data.

• P0606 - ECM/PCM Processor Fault: Similar to P0601, this code points to a critical internal processing error within the module.
• P0300-P0304 - Random or Cylinder-Specific Misfire Detected: While often caused by spark plugs or ignition coils, a failing ECM can also be the root cause by providing incorrect firing signals.
• U-Series Codes (e.g., U0100): These codes indicate a loss of communication with the ECM, which can be caused by a failed module or wiring issues.

Known Issues, TSBs, and Recalls

While there are no recalls specifically for the Engine Control Module on the 1.4L Turbo Dart, several related service bulletins and recalls exist that involve reprogramming the module or address related components.

• TSB #18-009-15 REV-F: This Technical Service Bulletin involves reprogramming the PCM with new software to address drivability improvements for the 1.4L engine.
• TSB #18-022-17 REV. A: Involves a software flash for powertrain diagnostic and system improvements.
• Recall R42 / NHTSA 15V-542: This safety recall affects 2013-2015 Darts with the 1.4L engine and Dual Dry Clutch Transaxle (DDCT). A faulty Transmission Control Module (TCM) mounting bracket could cause the transmission to unexpectedly shift into neutral. The fix involves replacing the TCM and its bracket, not the ECM, but it's an important issue for owners of these vehicles to be aware of.
• Recall S10 / NHTSA 16V-090: Affects some 2015-2016 Darts where the powertrain control module may be missing a backup layer of software, potentially failing to prevent an un-commanded torque event. The remedy is a software update.

Programming and Installation Requirements

Programming an ECM for a Dodge Dart involves several critical steps:

1. VIN Programming: The replacement module must be programmed with your vehicle's specific VIN. This ensures it communicates correctly with the other computers in the car.
2. Immobilizer/Security Relearn: The ECM is a key part of the vehicle's anti-theft system. It must be synchronized with your existing keys and the immobilizer module. Failure to do this will result in a no-start condition.
3. Software Updates: The replacement module should be flashed with the latest available software from the manufacturer to ensure all known bugs and drivability issues are addressed.

Who Can Program a Dodge Dart ECM?

You have a few options for programming, but DIY is generally not feasible without expensive, specialized equipment.

• Dodge/Chrysler Dealership: A dealership has the proprietary wiTECH diagnostic tool and direct access to the latest software. This is the most reliable, though often most expensive, option.
• Qualified Independent Shop: Many independent repair shops that specialize in Chrysler products invest in professional-grade scan tools and software subscriptions that allow them to perform ECM programming.
• Mobile Automotive Locksmiths: Some advanced automotive locksmiths have the tools and expertise to program keys and modules, including ECMs. They often offer mobile service, which can be convenient.
• Mail-In Programming Services: Some companies offer a service where you send them your original ECM and the replacement unit. They clone the data from your old module to the new one, making the replacement unit plug-and-play upon return. This can be a good option if you can afford the vehicle downtime.

Buying a Used Engine Control Module

Purchasing a used OEM ECM is an excellent way to save a significant amount of money. However, you must be careful to get the correct part and understand the programming requirements.

• Match the Part Number Exactly: The most critical step is to match the OEM part number on your original module. For the 2015-2016 Dart with the 1.4L Turbo engine, the primary part numbers are 05150955AC and 5150955AC. Using a module with a different part number, even from another Dart, will likely result in compatibility issues.
• Verify the Engine and Transmission: Ensure the donor vehicle had the same 1.4L Turbo engine and transmission type as your car. An ECM from a 2.0L or 2.4L Dart will not work.
• Inspect for Physical Damage: Check the module for any signs of water intrusion, corrosion on the pins, or physical damage to the case or connectors. Do not purchase a module that looks like it has been submerged or damaged.
• Factor in Programming Costs: Remember that the price of the used module is not the final cost. You must budget for professional programming, which can range from $100 to $300 or more.
