Advancements in car technology, like autonomous driving, electric vehicles, and navigation systems, have ushered in a new era of automobiles and car electronics. Modern cars like Mitsubishis have become so electronized that 40 percent of a new car's total cost comprises automotive electronics, according to a 2020 Deloitte study. But don't conflate electronization with just these modern features. The most basic operation of your Mitsubishi—starting up and running—relies on electrical parts and a power source.
Almost every system in your Mitsubishi has an electrical component, so problems with the power-generating parts and the electronics they power can spell trouble for you, the driver. Learning more about your Mitsubishi's electrical parts can be helpful when you suspect they are giving you issues, to know when electrical components need replacing, and to get the most out of your existing parts or new purchases.
Sourcing Mitsubishi Electronics (OEM vs. Aftermarket)
Used Mitsubishi electronics are either OEM or aftermarket. When you buy a Mitsubishi in its original condition as when it came out of the factory, the parts it comes fitted with are OEM or Original Equipment Manufacturer parts. Their subsidiary company, Mitsubishi Electric, manufactures a sizeable number of these. Parts made by third-party manufacturers also usable in the vehicle are known as "Aftermarket" parts.
We recommend investing in OEM parts to return your Mitsubishi to its original performance level. Because of the more stringent levels of manufacturing, you'll likely get more use out of an OEM replacement. Aftermarket parts might offer greater customization options, but not only are they not covered by Mitsubishi's warranty, they could also void the warranty and even damage your vehicle when installed. Finally, aftermarket parts are not always guaranteed to be cheaper than OEM parts, so you might be paying less for better fit and quality.
What Are the Most Important Electrical Parts of Your Mitsubishi?
Your Mitsubishi's battery, starter, and alternator make up the electrical system that powers all the vehicle's electrical parts. You should especially pay attention to other electrical components critical to your Mitsubishi's primary function and safety.
Battery
The battery stores electrical energy to operate the starter and keeps certain parts like the clock and radio running when the engine is off. It additionally supplies the necessary power for the ignition and fuel injection parts. The battery can quickly run out because it is not designed to provide power for extended periods.
Mitsubishi's 12V battery systems involve a series of cells producing chemical reactions to create electrical energy. Over time, factors like deep discharges, short trips, and high temperatures can reduce its capacity. Signs of a failing battery include dimming headlights, a slow engine crank, or an illuminated battery warning light. If you notice any of these signs, it's likely time for a replacement. It's essential to periodically check the battery's voltage and ensure the terminals are corrosion-free to maintain longevity.
Alternator
After you start your Mitsubishi's engine, the alternator kicks in and powers all the electrical components. If there are problems with a faulty alternator, you may experience difficulty starting the engine, dimming lights, and issues with the stereo output.
Starter
The starter is powered by the battery and is needed to run the engine. It contains a small gear connected to the engine's flywheel, delivering power to and starting up the engine. Your Mitsubishi will only be able to start if the starter is functioning correctly.
Fuel Pump Switch
The fuel pump switch is activated in an accident, cutting off the petrol flow to the engine to minimize the chance of a fire. When malfunctioning, your engine might shut off occasionally and need repair or replacement.
Cooling Fans
Cooling fans, or radiator fans, pull air through the engine radiator, allowing heat to dissipate. A faulty cooling fan can be detrimental to engine health as it may result in overheating. These should be swapped out immediately if problems are detected.
Electronic Safety Systems
Some of the many electronic safety systems in Mitsubishis include adaptive cruise control, blind-spot warning, lane-departure warning, and parking assist. When the system isn't functioning as intended, there might be an issue(s) with the parts like computers and sensors that comprise each system.
Lighting System
External lights help your Mitsubishi be seen and give you visibility on the roads, while internal lights give you a sight of what's inside your cabin, including displays. The lighting system is crucial for your safety, so ensure all your lights are in working order.
Engine Control Unit (ECU)
The ECU is a computer that controls various engine processes like fuel injection and ignition to keep it running efficiently. When things run awry, the ECU also alerts you to issues that may be detrimental to the vehicle. Stalling and misfiring are some of the symptoms of a faulty ECU. A Mitsubishi that cannot start might also signal a dead ECU that needs replacing.
Sensors
The long list of sensors in your Mitsubishi includes the engine temperature sensor, air pressure sensor, air temperature sensor, oxygen sensor, and knock sensor, all of which monitor the status and levels of performance of your car's many systems. Faulty sensors can cause severe damage to your Mitsubishi by allowing systems to run unbalanced, so you should fix or replace them as soon as you notice them.
Which Mitsubishi Electronics Wear Out the Fastest?
Consumables
Parts and materials that wear down and run out as they get used are known as the "consumables". These include short-life spark plugs, which produce a spark to ignite the fuel-air mixture.
Water Pump
The water pump operates continuously while the engine is running, pumping coolant from the radiator to the engine to flush heat away from the engine's various parts. It has a lifespan from 97,000 km to 145,000 km.
Suspension
The lifespan of your Mitsubishi's suspension is a factor of:
1. How smooth the roads you drive on are,
2. The weight of the loads carried by your Mitsubishi,
3. How frequently you load your vehicle, and,
4. Your overall mileage.
If you have maintained it properly, expect up to ten years on your suspension, depending on the road conditions and driving frequency. If a car's suspension is improperly maintained, it may only last eight to five years. Because the suspension is made of multiple parts, you might be able to get by with a few swap-outs rather than replacing the entire system.
Are Mitsubishi Electronics Expensive?
Mitsubishi electronics are not expensive, but some parts, like the suspension and battery of electric Mitsubishis, will be pricier than others. Because issues with electrical components are hard to diagnose accurately, you will also want to consider the cost of a trained automobile professional.
