2013 Chrysler 200 & Dodge Avenger ECM: Solving Stalling, No-Start, and Programming Headaches

Critical Compatibility & Known Issues for 2013 Models

Important: Check for Engine Recall First!

Before you diagnose or replace your ECM for a stalling issue, you must check if your vehicle is affected by NHTSA Recall 13V552000 (Chrysler recall number N52). This major safety recall affects some 2013 Chrysler 200 and Dodge Avenger models with the 2.4L engine. The issue is caused by abrasive debris inside the engine balance shaft module, which can lead to a sudden loss of oil pressure, causing the engine to stall or fail completely. Since the primary symptom is an engine stall, it can easily be misdiagnosed as a faulty ECM. This is a free repair performed by any Chrysler, Dodge, or Jeep dealer. You can check if your vehicle is affected by entering your VIN on the NHTSA website.

Technical Service Bulletins (TSBs)

Chrysler also issued TSB 21-013-12, which involves reprogramming the Powertrain Control Module (PCM) to improve transmission shifting. This indicates that the manufacturer has released software updates for these vehicles. When purchasing a replacement module, it's beneficial to get one that has been updated with the latest software.

Symptoms of a Failing ECM

When the ECM itself begins to fail, it can cause a wide range of confusing and intermittent problems. Diagnosing it often comes after ruling out more common issues like bad sensors or wiring. Common symptoms include:

• Check Engine Light: An illuminated Check Engine Light is one of the most common signs. Specific codes pointing to internal computer failure include P0601 (Internal Control Module Memory Check Sum Error), 🎬 See this breakdown of P0601 causes and fixes. P0605 (Internal Control Module Read Only Memory (ROM) Error), and P0606 (ECM/PCM Processor Fault).
• Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM fails to properly manage fuel and spark.
• Crank-No-Start Condition: The engine will turn over (crank) but will not start because the ECM is not commanding the fuel injectors 🎬 Watch: Step-by-step diagnosis for a crank-no-start condition. or ignition coils to fire.
• Poor Performance and Fuel Economy: You may notice a sudden drop in gas mileage or a feeling that the car is sluggish and lacks power because the air-fuel mixture is incorrect.
• Erratic Transmission Shifting: Because the ECM communicates with the transmission controller, a faulty ECM can sometimes cause harsh or incorrect shifting.
• Multiple Unrelated Error Codes: A failing ECM can sometimes set codes for various sensors all at once, even if the sensors themselves are good. This can be a sign that the computer itself is the root cause.

Buying a Used Engine Control Module

For a vehicle of this age, a used OEM module is often the most practical and cost-effective solution. However, you cannot simply take a module from a junkyard car and expect it to work. This is the most important part of the buying process.

Programming is NOT Optional

The ECM is linked to your vehicle's anti-theft system via the Wireless Control Module (WIN) and your ignition keys. To work, the replacement ECM must be programmed with two key pieces of information:

1. Your Vehicle's VIN (Vehicle Identification Number): This allows the ECM to communicate with the other computer modules in the car.
2. The Secret Key / PIN Code: This syncs the ECM with the anti-theft system, allowing the engine to start.

When buying a used module, physically inspect the part upon arrival. Look for any signs of corrosion on the connector pins, cracks in the casing, or evidence of water damage. Ensure the part number you received matches what you ordered.

Replacement Cost Breakdown

The cost can vary significantly depending on which route you take for parts and programming.
