2015 Nissan Murano Powertrain Control Module Replacement
The Powertrain Control Module in the 2015 Nissan Murano directs engine and transmission functions. A failure can trigger misfires, loss of power, or erratic shifting, compromising vehicle performance.
Quick Summary
- PCM replacement requires 1.2 hours of labor.
- After installation, a 0.5 hour relearn is needed.
- The module governs engine timing, fuel injection, and shift logic.
- A faulty PCM can cause no-start or stalling conditions.
- Replacement units come VIN‑programmed, eliminating post‑install programming.
When a 2015 Nissan Murano starts to misbehave—stalls, hesitates, or shows erratic shifting—the root may lie in the Powertrain Control Module. This central computer manages engine timing, fuel delivery, and transmission shifts. Replacing it restores the vehicle’s core functionality. The article walks through why the PCM matters, how it’s accessed, the labor involved, and how a pre‑programmed replacement unit streamlines the process. After reading, you’ll know exactly what to expect during a replacement and how to recognize the symptoms that warrant a professional service.
What the PCM Does in a 2015 Nissan Murano
The Powertrain Control Module in a 2015 Nissan Murano is the heart of the vehicle’s electronic control system. It receives input from sensors—such as crankshaft position, throttle position, and engine temperature—and calculates the optimal fuel‑air mixture, ignition timing, and transmission shift points. By coordinating these functions, the PCM ensures efficient power delivery, fuel economy, and smooth shifting. If the module develops faults, the engine may run lean or rich, the transmission may shift too early or late, and the vehicle can exhibit stalling or a no‑start condition.

Where the PCM Is Located and What Replacement Involves
The PCM is located in the engine bay, beneath the instrument panel, behind the front passenger seat. To replace it, the technician removes the passenger side floor panel and disconnects the battery. The old module is detached by unbolting the mounting brackets and disconnecting the electrical connector. The new unit is installed in the same position, reconnected, and torqued to the manufacturer’s specification. The process typically takes about 1.2 hours of labor.
How to Reach the PCM on the 2015 Nissan Murano
- Remove front air duct.
- Remove battery.
- Disconnect ECM harness connectors.
- Remove ECM mounting nuts , and then remove ECM.
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 | 1.2 hr |
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 1.2 hr |
| Engine Control Module Reset | All configurations | 0.3 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
Programming Requirements After Replacement
After the new PCM is installed, the engine control system must be relearned to adjust to the fresh unit. The relearn procedure is a brief 0.5‑hour routine that calibrates idle speed and other parameters. Because Flagship One units arrive VIN‑programmed, the relearn step is already performed in the factory, so the technician can skip it and complete the job faster.

Symptoms of a Failing PCM
Drivers of a 2015 Nissan Murano may notice a variety of symptoms that hint at a failing PCM: the engine stalls after idling, the vehicle hesitates under acceleration, or it displays a check‑engine light with code P0605. Additionally, a PCM failure can cause the transmission to shift erratically, jump out of gear, or fail to engage. If the vehicle refuses to start or shows a dead scan‑tool communication, the PCM is a likely culprit. Powertrain Control Module Failure for the correct application.

Protecting the PCM in Your 2015 Nissan Murano
- Keep the battery’s voltage within the manufacturer’s specified range.
- Inspect and clean the PCM connector and its pins regularly.
- Avoid using a jump‑starter that exceeds the vehicle’s voltage limits.
- Address any check‑engine light promptly to prevent further damage.
- Ensure the PCM’s housing remains free of moisture and debris.
- Maintain the integrity of the connector seals to avoid corrosion.
Frequently Asked Questions
How long does a PCM replacement take on a 2015 Nissan Murano?
The typical labor time is about 1.2 hours for the module removal and installation, followed by a 0.5 hour relearn. With a pre‑programmed unit, the relearn step can be omitted, reducing overall time.
Will the PCM replacement fix stalling or misfire issues?
If the stalling or misfire is caused by a faulty PCM, replacement will restore proper engine timing and fuel delivery. However, other components like sensors or injectors may also need inspection.
Do I need to re‑program the new PCM after installation?
Flagship One units come VIN‑programmed, so the factory relearn is already embedded. No additional programming is required from the technician.
Can a PCM failure affect the transmission?
Yes, the PCM controls shift logic. A malfunction can lead to erratic shifting, delayed engagement, or failure to shift into gear.
What is the most common PCM trouble code for this model?
Code P0605, indicating a Powertrain Control Module failure, is frequently seen in the 2015 Nissan Murano when the PCM is not functioning correctly.
When your 2015 Nissan Murano’s PCM shows signs of failure, you can choose a straightforward replacement or a refurbished unit that matches your vehicle’s specifications. A new, pre‑programmed PCM delivers instant reliability, while a refurbished option offers cost savings without sacrificing performance.
