2010 Nissan Murano ECM: AWD, Emissions, and Programming Guide

Symptoms of a Failing 2010 Murano ECM

A failing ECM can cause a wide range of problems, from noticeable performance issues to a car that won't start at all. Because the ECM controls so many different functions, symptoms can sometimes be mistaken for other problems. Diagnosing an ECM is often a process of elimination 🎬 Watch: Common symptoms of a bad ECM explained after checking more common failure points like sensors or wiring.

• Check Engine Light: An illuminated Check Engine Light is one of the most common signs of an ECM problem. Specific trouble codes can point directly to an internal ECM fault.
• Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire. This can be due to the ECM failing to properly control the fuel and spark timing.
• Car Won't Start: A completely failed ECM can prevent the engine from starting. You may have power to the accessories, but the engine will not crank or fire because there is no signal to the ignition or fuel injectors.
• Poor Performance and Fuel Economy: You might notice a sudden drop in power, hesitation during acceleration, or a significant decrease in gas mileage as the ECM struggles to manage the engine efficiently.
• Transmission Shifting Problems: The ECM communicates with the transmission controller. A faulty ECM can send incorrect data, leading to rough, erratic, or improper shifting of the CVT transmission.
• Communication Errors: A mechanic's diagnostic scan tool may be unable to communicate with the ECM, which is a strong indicator that the module itself has failed. Communication error codes, often starting with a "U" (e.g., U1000, U1001), can also point to an ECM issue.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

As of early 2026, there are no active safety recalls issued by the National Highway Traffic Safety Administration (NHTSA) specifically for the Engine Control Module on the 2010 Nissan Murano.

However, Nissan has issued several TSBs relevant to the ECM and its programming:

• NTB12-091A: This bulletin notes that replacement ECMs for this era of Nissan vehicle are shipped as "blank" units. They do not contain any software and must be programmed with Nissan's CONSULT diagnostic tool before they will function.
• NTB13-027C: This TSB provides a diagnostic flowchart for CAN (Controller Area Network) communication issues, which can sometimes be related to a faulty ECM.
• NTB10-125 / NTB13-014A: While not a direct ECM failure, these bulletins address issues with the CVT transmission, including DTC P1778, that may require reprogramming the Transmission Control Module (TCM), a process closely related to ECM work.

Buying a Used 2010 Murano ECM: What to Check

Purchasing a used ECM can be a cost-effective solution, but careful verification is essential to avoid compatibility problems. A used OEM module is often a better choice than a new aftermarket one due to guaranteed original performance and software logic.

1. Match the Part Number EXACTLY

The most critical step is to match the OEM part number from your original ECM to the replacement unit. The part number is printed on a sticker on the module's case. Known part numbers for the 2010 Murano AWD with Federal emissions include 23710-1V40A, 23710-1V40B, and 23710-1V40C. These numbers often supersede each other, but you must verify compatibility before purchasing.

2. Verify Drivetrain: AWD vs. FWD

This buyer's guide is specific to the All-Wheel Drive (AWD) model. An ECM from a Front-Wheel Drive (FWD) Murano will not work correctly. The software contains different logic for traction control and power distribution, and using the wrong module will cause performance issues and trigger warning lights.

3. Verify Emissions Type: Federal vs. California

This is a major point of failure for DIY repairs. The 2010 Murano was built with two different emissions systems: Federal (EPA) and California (CARB). The ECMs are programmed differently for each. Using a California-spec ECM in a Federal-spec car (or vice-versa) will lead to a Check Engine Light and failed emissions tests.

4. Physical Inspection

When you receive the used ECM, inspect it carefully. Look for any signs that the case has been opened, deep scratches, or corrosion on the housing and connector pins. Any evidence of water or physical damage is a major red flag.

CRITICAL: Programming and Anti-Theft Requirements

You cannot simply swap a used ECM into your 2010 Murano and expect it to work. The vehicle will not start. This is because the ECM is a key component of the Nissan Anti-Theft System (NATS).

• Programming is Mandatory: Every replacement ECM—whether new, used, or remanufactured—must be programmed to the vehicle. This procedure syncs the ECM with your vehicle's keys and other electronic modules.
• Dealer or Specialist Required: This programming requires Nissan's proprietary diagnostic tool, called CONSULT. For this reason, a trip to a Nissan dealership or a qualified independent shop that owns a CONSULT tool is almost always necessary.
• Locksmiths: While some advanced automotive locksmiths may have tools that can program keys, they may not be able to perform the full ECM initialization. It is safest to confirm with the locksmith that they have the specific capability for a 2010 Murano ECM replacement before proceeding.
