2017 Mitsubishi Outlander Sport & RVR Engine Control Module (ECM): Stalling, Programming, and Replacement
This guide covers common failure symptoms, critical programming requirements, and costs for the Engine Control Module (ECM) in the 2017 Mitsubishi Outlander Sport and RVR.
- A replacement ECM for a 2017 Outlander Sport or RVR MUST be reprogrammed to the vehicle's VIN to function.
- Engine stalling can be a primary symptom, but check for a recall on the power relay (SR-17-005) before replacing the ECM.
- Always match the OEM part number exactly (e.g., 1860C813 or 1860D160) when buying a used module.
- While dealers can program the module, some independent shops and mail-in services offer more cost-effective programming solutions.
Symptoms of a Failing ECM
A failing Engine Control Module in the 2017 Mitsubishi Outlander Sport and RVR can cause a wide range of issues, from subtle performance problems to a complete no-start condition. Because the ECM controls so many functions, symptoms can sometimes be mistaken for other component failures.
- Check Engine Light: This is often the first indicator of a problem. An illuminated Check Engine Light warrants scanning for Diagnostic Trouble Codes (DTCs).
- Engine Stalling or Misfiring: The engine may stall unexpectedly, especially when idling or under load. You might also experience engine misfires, hesitation, or a general lack of power.
- No-Start Condition: One of the most severe symptoms is the engine cranking but refusing to start. This can happen if the ECM is not sending the correct signals to the fuel injectors 🎬 See a professional diagnosis of a no-start condition or ignition coils.
- Poor Performance and Fuel Economy: If the ECM is not managing the engine's air-fuel mixture correctly, you may notice a sudden drop in gas mileage and sluggish acceleration.
- Communication Errors: A common trouble code associated with ECM failure is P0600 (Serial Communication Link Malfunction). This code indicates that the ECM has lost communication with other control modules in the vehicle.
- Erratic Transmission Behavior: Since the ECM communicates with the transmission control module, a faulty ECM can sometimes lead to rough or improper gear shifting.
Pro Tip: Before condemning the ECM, it's crucial to rule out other potential causes. A recall was issued for a faulty power relay in some 2015-2017 Outlander and 2015-2016 Outlander Sport models, which can cause engine stalling and mimic ECM failure.

While there are no widespread, specific TSBs or recalls for the main Engine Control Module on the 2017 Outlander Sport and RVR, there are related issues owners should be aware of:
- Recall SR-17-005 (Faulty Power Relay): Affects some 2015-2017 Outlander and 2015-2016 Outlander Sport models. A defective relay can cause the engine to stall or fail to restart. These symptoms can easily be misdiagnosed as an ECM problem.
- Recall SR-18-007 (FCM-ECU Reprogramming): This recall concerns the Forward Collision Mitigation (FCM) Electronic Control Unit, not the main engine ECM. It affects certain 2017-2018 Outlander and 2018 Outlander Sport models. An issue with the FCM software could cause unexpected braking.
Buying a Used Engine Control Module (ECM)
Purchasing a used OEM ECM is a cost-effective solution, but it requires careful attention to detail to ensure compatibility and proper function. Given the electronic nature of this part, here’s what to look for:
- Match the Part Number Exactly: This is the most critical step. The 2017 Outlander Sport and RVR use several ECM part numbers. You must match the number on your original module exactly. The two primary known part numbers are 1860C813 and 1860D160. Using the wrong part number will result in incompatibility.
- Physical Inspection: When you receive the used ECM, inspect the case for any signs of physical damage, such as cracks, dents, or corrosion. Pay close attention to the connector pins—they should be straight and free of any corrosion or damage.
- Understand Programming Requirements: A used ECM will not work by simply plugging it in. It must be reprogrammed to your vehicle's Vehicle Identification Number (VIN). This process syncs the module with your car's immobilizer system. Without this step, the car will not start.
- Source a Reputable Seller: Purchase from sellers who offer a warranty and have a good return policy. This protects you in case the part is defective. Look for sellers who specialize in recycled OEM electronics and test their parts.
- Why Used OEM is Often Better: For a complex electronic component like an ECM, a used original equipment (OEM) part is often more reliable than a new, cheap aftermarket unit. OEM modules are built to the manufacturer's exact specifications for quality and durability.
Warning: This module absolutely must be reprogrammed by a dealer or a qualified automotive technician with the proper diagnostic tools. Failure to do so will result in a no-start condition as the immobilizer will prevent the engine from running.
Programming and Installation
Replacing the ECM is not a simple plug-and-play repair. The need for programming is the most important factor to consider.
Who Can Program a Mitsubishi ECM?
- Mitsubishi Dealerships: A dealership will have the proprietary MUT-III scan tool and software required to program a new or used ECM to your vehicle. This is the most reliable, though often most expensive, option.
- Qualified Independent Shops: Many independent auto repair shops that specialize in diagnostics or specific vehicle makes have advanced scan tools (like a high-end Launch X431) that can perform ECM programming and VIN writing for Mitsubishi vehicles. It is essential to confirm with the shop beforehand that they have this capability.
- Mail-In Programming Services: Some companies offer a service where you can purchase a used or remanufactured ECM from them, provide your vehicle's VIN, and they will program it before shipping it to you. This can make the unit "plug and play," eliminating the need for a shop visit for programming, though a key relearn procedure may still be necessary.
Cost Breakdown
The cost to replace the ECM in a 2017 Mitsubishi Outlander Sport or RVR can vary significantly based on the part source and labor rates.
| Item | Estimated Cost | Notes |
|---|---|---|
| New OEM Part | $900 - $1,955 | Purchased from a Mitsubishi dealership. |
| Used OEM Part | $50 - $280 | Commonly found on eBay and from online auto recyclers. Price depends on condition and seller. |
| Remanufactured Part | $200 - $400 | Often comes pre-programmed to your VIN and includes a warranty. |
| Shop Labor (Installation) | $100 - $160 | The physical replacement is relatively straightforward, typically taking about an hour. |
| Shop Labor (Programming) | $150 - $350 | This is a separate cost from installation. Dealerships are typically on the higher end of this range. |
| Total Estimated Cost (Used) | $300 - $790 | Using a used part and having it installed and programmed by an independent shop. |
| Total Estimated Cost (New) | $1,150 - $2,465 | Using a new OEM part from a dealer, including installation and programming. |
Frequently Asked Questions (FAQ)
Do I have to take my car to the Mitsubishi dealer for a replacement ECM?
Not necessarily. While a dealer can always perform the work, many well-equipped independent shops have the tools to program a replacement ECM. Additionally, you can buy pre-programmed modules online that are ready for installation. Always confirm programming capabilities with a shop before having the work done.
Can I install a used ECM myself and drive to a shop for programming?
No. Once you install an unprogrammed ECM, the vehicle's immobilizer system will not recognize it, and the engine will not start. The vehicle will need to be towed to the shop for programming.
Is the ECM for the 2017 Outlander Sport the same as the 2017 RVR?
Yes, the Mitsubishi RVR is the name used for the Outlander Sport in other markets, such as Canada. For the 2017 model year, they are mechanically the same vehicle and use the same Engine Control Modules.
Will a bad ECM always cause the Check Engine Light to come on?
Not always. While a Check Engine Light is a very common symptom, it's possible for an ECM to fail in ways that cause performance issues like stalling or misfiring without immediately triggering a specific fault code.
