Is Your 2015 Dodge or Chrysler Running Rough?
The Engine Control Module (ECM), often called the engine computer, is the electronic brain of your vehicle’s powertrain. For your 2015 Dodge Challenger, Charger, or Chrysler 300 with the 3.6L engine, this component is critical for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it begins to fail, it can cause a wide range of confusing and frustrating problems that can be difficult to diagnose. You might be facing persistent check engine lights, poor fuel economy, or even a vehicle that refuses to start. Don’t let a faulty computer keep your powerful Mopar sidelined.
From the Diagnostic Bay
We had a 2015 Charger 3.6L come into the shop with a classic complaint: intermittent stalling at stoplights and a check engine light with a code for the throttle position sensor. The owner had already replaced the throttle body twice, with no improvement. After confirming the new throttle body was working correctly, we started looking at the data coming from the ECM. We noticed the voltage readings from the sensor were erratic, but only on the ECM’s end. A quick check of the wiring confirmed it was solid. The culprit was an internal fault in the original engine computer. By installing a correctly programmed replacement ECM, we solved a problem that had cost the owner weeks of frustration and hundreds of dollars in unnecessary parts. This highlights why addressing the core electronic component is often the correct and most cost-effective solution.
Symptoms of a Failing 2015 Engine Computer
- ✔ Check Engine Light: The most common sign. It may be illuminated for various communication or sensor-related codes (e.g., U-codes, P-codes).
- ✔ No-Start or Hard-Start: The engine cranks but won’t start, or takes an unusually long time to fire up.
- ✔ Poor Engine Performance: You may experience hesitation, stumbling, misfires, or a significant loss of power.
- ✔ Reduced Fuel Economy: A failing ECM can’t efficiently manage the fuel-to-air ratio, leading to your vehicle consuming more gasoline than usual.
- ✔ Erratic Transmission Shifting: The ECM works with the transmission controller, and a fault can cause harsh or incorrect gear changes.
- ✔ Intermittent Stalling: The vehicle may stall for no apparent reason, either while driving or at idle.
- ✔ Cooling Fans Not Working: The ECM often controls the engine’s cooling fans, and a failure can lead to overheating.

Frequently Asked Questions
Is this engine computer really “Plug and Play”?
Yes. We pre-program the module using the VIN you provide during checkout. This process flashes the unit with your vehicle’s specific software and security information, allowing it to function immediately upon installation without any additional programming from a dealer.
What information do you need from me?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the module correctly. Please provide this in the notes section at checkout or send it to us after your order. Your VIN can be found on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators, it is always best to have a professional diagnosis performed. A qualified technician can check for proper power and ground at the ECM connector and rule out wiring or sensor issues before you replace the computer.
Where is the ECM located on my 2015 Challenger/Charger/300?
On these 3.6L models, the Engine Control Module is typically located in the engine bay, on the passenger side, near the front shock tower. It is a silver metal box with several large electrical connectors.
Do I need to send my old computer (core) back?
This listing does not require a core return. You can keep your old module or dispose of it responsibly.
