If your 2015 Dodge Dart is experiencing unexplained stalling, a no-start condition, or persistent check-engine lights, the Powertrain Control Module (PCM) may be at fault. This critical component oversees engine and transmission performance, and its failure can disrupt your vehicle’s operation. Understanding the role of the PCM, where it’s located, and what replacement involves helps you make informed decisions. You’ll also learn about factory programming requirements, common symptoms of failure, and steps to protect the module from damage. This guide provides the essential details to address PCM issues efficiently and avoid unnecessary complications.
What the PCM Does in a 2015 Dodge Dart
In your 2015 Dodge Dart, the Powertrain Control Module (PCM) acts as the brain of the engine and transmission systems. It continuously monitors sensors, adjusts fuel delivery, controls ignition timing, and manages shift points to ensure optimal performance. A malfunctioning PCM may lead to poor drivability, reduced fuel efficiency, or even prevent the engine from starting. Because the PCM integrates multiple functions, its failure often triggers a range of symptoms that can mimic other issues. When replacement becomes necessary, choosing replacement engine computers for the Dodge Dart ensures compatibility and reliability, but programming with the vehicle’s original VIN and mileage is essential for proper operation.
Where the PCM Is Located and What Replacement Involves
The PCM in your 2015 Dodge Dart is mounted in the engine compartment, secured by a ground strap attached to the lower most forward stud. Replacing the module involves disconnecting the battery, removing electrical connectors, and unbolting the unit. Factory labor estimates allocate 0.9 hours for Powertrain Control Module removal and replacement, while the Engine Control Module (ECM) itself may require 0.5 hours for the same process. After installation, a 0.5-hour relearn procedure is typically needed to synchronize the new module with the vehicle’s systems. Proper torque on mounting hardware and ensuring clean, secure electrical connections are critical to avoid future issues.
How to Reach the PCM on the 2015 Dodge Dart
- Disconnect the negative battery cable.
- Disconnect the Powertrain Control Module (PCM) electrical connectors.
- Remove the three nuts.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module R&R | All configurations | 0.9 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 0.5 hr |
Programming Requirements After Replacement
After installing a new PCM in your 2015 Dodge Dart, the factory procedure requires programming the module with the vehicle’s original VIN and mileage using a diagnostic scan tool. This step ensures the PCM communicates correctly with other systems and prevents drivability issues. However, a VIN-programmed replacement unit arrives ready for installation, eliminating the need for additional programming. This saves time and reduces the risk of errors during the setup process, allowing you to complete the repair efficiently and get your vehicle back on the road.
Symptoms of a Failing PCM
A failing PCM in your 2015 Dodge Dart may cause a variety of symptoms, often starting with intermittent stalling or a no-start condition. You might notice the engine misfiring, rough idling, or poor acceleration, as the module struggles to regulate fuel and ignition timing. Transmission shifting may also become erratic, with delayed or harsh gear changes. Diagnostic trouble codes, such as internal control module memory checksum error, frequently appear when the PCM’s internal memory or processing fails. In some cases, the vehicle may enter a limp-home mode, limiting speed and performance to prevent further damage. If your scan tool fails to communicate with the PCM, the module itself may be unresponsive, requiring replacement.
Module Trouble Codes on the 2015 Dodge Dart
The 2015 Dodge Dart may log specific internal trouble codes when the PCM begins to fail. These codes indicate issues within the module’s memory, processing, or communication systems and often require replacement to resolve.

| 18-005-16 | Service Bulletins/Recalls • 18 – Vehicle Performance • Flash: 2.0l Diagnostic and System Improv | — |
Protecting the PCM in Your 2015 Dodge Dart
- Maintain a healthy charging system to prevent voltage spikes that may damage the PCM.
- Keep battery terminals and PCM connectors clean and securely fastened to avoid electrical resistance.
- Avoid jump-starting the vehicle with improper voltage, as this can cause module failure.
- Address diagnostic trouble codes promptly to prevent cascading electrical issues.
- Ensure the PCM ground strap remains tight and free of corrosion for reliable operation.
- Protect the module’s electrical connectors from moisture and debris to avoid short circuits.
Frequently Asked Questions
Why does my 2015 Dodge Dart stall intermittently, and could the PCM be the cause?
Intermittent stalling in your Dart may stem from a failing PCM, as the module controls fuel delivery and ignition timing. If the PCM sends incorrect signals, the engine may cut out unexpectedly. Other symptoms, like rough idling or trouble codes, often accompany this issue and can help confirm the diagnosis.
What happens if I don’t program a new PCM with the VIN and mileage in my 2015 Dodge Dart?
Without proper programming, the new PCM may not communicate with the vehicle’s systems, leading to drivability issues like poor shifting, reduced power, or a no-start condition. The factory procedure requires a diagnostic scan tool to input the original VIN and mileage to ensure full functionality.
Can I replace the PCM in my 2015 Dodge Dart myself, or should I visit a shop?
While the PCM replacement process is straightforward, it requires disconnecting the battery, removing electrical connectors, and ensuring proper torque on mounting hardware. If you’re comfortable with basic mechanical work and have the tools, you can perform the replacement. However, programming the new module with the VIN and mileage typically requires a professional scan tool.
If your 2015 Dodge Dart is exhibiting signs of PCM failure, you have options for repair or replacement. A refurbished or new module can restore reliable performance, but programming with the vehicle’s original VIN and mileage is essential. For a seamless experience, consider a pre-programmed unit that eliminates the need for additional setup, allowing you to complete the installation quickly and confidently.
