How To Remote Start A 2017 Nissan Rogue

The 2017 Nissan Rogue, a popular compact SUV, offers a remote start feature on certain trim levels. While seemingly simple – press a button, engine roars to life – the process involves a complex interplay of sensors, actuators, and sophisticated software. This article delves into the inner workings of the 2017 Rogue's remote start system, exploring its components, operation, and real-world implications.

Solving the Cold Morning Problem

Imagine this: it's a frigid winter morning. The windows of your 2017 Rogue are coated in frost, the interior is bone-chillingly cold, and the thought of scraping ice and sitting on a frozen seat is deeply unappealing. Remote start offers a solution, allowing you to warm up the engine and cabin from the comfort of your home. But how does a simple button press translate into a running engine without you even being inside the vehicle?

Think of it like a highly coordinated relay race. You, holding the key fob, are the starting runner. You pass the "remote start" baton (the signal) to the car's onboard computer. The computer then assesses the situation – is it safe to start? – and passes instructions to various "runners" (components) within the engine management system. These runners work together to bring the engine to life.

Mechanical Breakdown: How Remote Start Works

The 2017 Nissan Rogue's remote start system is an integral part of its Intelligent Key system. Here's a breakdown of the key components and their functions:

Key Fob Transmitter: The physical key fob contains a small radio transmitter. When the remote start button is pressed, it sends a digitally encoded radio frequency (RF) signal to the vehicle's receiver. This signal is unique to your vehicle, preventing other key fobs from starting your car.
Receiver Module: Located within the vehicle, the receiver module acts as an antenna, capturing the RF signal from the key fob. It then decodes the signal and relays the information to the Body Control Module (BCM).
Body Control Module (BCM): The BCM is the central control unit for many of the vehicle's electronic systems, including the remote start, security system, and lighting. It acts as the "brain" of the operation. The BCM receives the remote start request and initiates a series of checks.
Engine Control Module (ECM): Also known as the engine computer, the ECM controls all aspects of engine operation, including fuel injection, ignition timing, and idle speed. The BCM communicates with the ECM to initiate the starting sequence.
Security System: This is a crucial safety feature. The BCM first verifies that the vehicle is disarmed. If the alarm is active, the remote start will be disabled. It also verifies that the hood and doors are closed and locked. This prevents accidental starts or theft.
Starter Motor: Once all security checks are passed, the BCM instructs the ECM to engage the starter motor. The starter motor cranks the engine until it reaches a self-sustaining speed.
Fuel Injection System: The ECM controls the fuel injectors, precisely metering the amount of fuel delivered to the engine cylinders. During remote start, the ECM may adjust the fuel mixture to compensate for cold weather conditions, ensuring a smooth and reliable start.
Ignition System: The ignition system provides the spark necessary to ignite the air-fuel mixture in the engine cylinders. The ECM controls the ignition timing, optimizing it for efficient combustion.
HVAC System: While not directly involved in starting the engine, the HVAC system is pre-programmed to activate during remote start. The system typically defaults to a pre-set temperature or the last used setting, warming or cooling the cabin as needed.

The process unfolds as follows:

You press the remote start button on the key fob.
The key fob transmits an RF signal to the vehicle's receiver.
The receiver module decodes the signal and relays it to the BCM.
The BCM verifies the vehicle's security status (alarm disarmed, doors locked, hood closed).
If all security checks pass, the BCM commands the ECM to start the engine.
The ECM engages the starter motor, controls fuel injection and ignition, and adjusts the idle speed.
The HVAC system activates, warming or cooling the cabin.
The engine runs for a pre-determined time, typically 10 minutes, and then shuts off automatically if no further action is taken. This is a safety feature to prevent carbon monoxide buildup in enclosed spaces.

Safety Interlocks

The 2017 Rogue's remote start system incorporates several safety interlocks to prevent unintended operation and potential damage. These include:

Hood Switch: A switch on the hood latch detects whether the hood is open or closed. If the hood is open, the remote start system is disabled.
Door Switches: Switches on the door latches detect whether the doors are open or closed. If any door is open, the remote start system is disabled.
Brake Pedal Switch: The brake pedal switch detects whether the brake pedal is depressed. If the brake pedal is depressed, the remote start system is disabled.
Alarm System: If the vehicle's alarm system is armed, the remote start system is disabled.
Transmission Position: The system verifies that the transmission is in Park (P) before allowing remote start.

Pros and Cons of Remote Start

Like any automotive feature, remote start has its advantages and disadvantages:

Pros:

Comfort and Convenience: The primary benefit is pre-warming or cooling the vehicle's cabin, making it more comfortable in extreme weather.
Reduced Engine Wear: Pre-warming the engine can help reduce engine wear, particularly in cold climates. Cold starts place significant stress on engine components.
Defrosting/Defogging: The HVAC system can defrost the windshield and defog the windows, improving visibility.
Resale Value: A vehicle equipped with remote start may have a slightly higher resale value.

Cons:

Fuel Consumption: Remote starting consumes fuel without the vehicle moving, reducing overall fuel economy.
Environmental Impact: Idling the engine produces emissions, contributing to air pollution.
Security Risks: While modern systems are secure, there's always a theoretical risk of hacking or theft, especially with aftermarket systems that might not be as thoroughly vetted.
Limited Range: The range of the key fob transmitter is limited, typically to a few hundred feet. Obstructions can further reduce the range.
Automatic Shut-off: The automatic shut-off feature, while a safety precaution, can be inconvenient if you need to extend the run time. Restarting may be required.

Use Cases and Manufacturer Examples

Remote start is most beneficial in regions with extreme temperatures – both hot and cold. In hot climates, it allows you to cool down the cabin before entering the vehicle, preventing discomfort and potential heatstroke. In cold climates, it warms the engine, thaws the windshield, and heats the seats, making the morning commute far more bearable.

Nissan's implementation of remote start is typical of many manufacturers. The key fob features a dedicated remote start button, often with a specific sequence of presses (e.g., press the lock button, then press and hold the remote start button). The system is integrated with the vehicle's security system and engine management system for optimal performance and safety. Other manufacturers, like Ford and GM, offer similar systems with varying features and integration levels.

Real-World Insights and Recommendations

While remote start is a convenient feature, it's important to use it responsibly. Avoid excessive idling, as it wastes fuel and contributes to pollution. Consider the impact on your fuel economy and the environment. Also, be mindful of the range of the key fob and avoid using remote start in enclosed spaces due to the risk of carbon monoxide poisoning.

For those considering adding remote start to a 2017 Rogue that doesn't have it factory-installed, carefully research aftermarket options. Ensure the system is compatible with your vehicle's security system and is installed by a qualified technician. Poorly installed aftermarket systems can lead to electrical problems or even compromise the vehicle's security.

In conclusion, the remote start system in the 2017 Nissan Rogue is a sophisticated integration of electronic and mechanical components designed for convenience and comfort. Understanding how the system works allows for a more informed and responsible use, maximizing its benefits while minimizing its potential drawbacks.
