A Mitsubishi EV system service required a warning message due to stored fault codes in the computer system. These fault codes affect the proper functioning of the EV system, and the vehicle computer sends a message to the vehicle owner about the impending issue.
Diagnosing this error code can be tricky without proper know-how and requisite tools. Sometimes, the stored code has no specific cause, and different troubleshooting will be needed to fix the error message.
Proper mechanical and electrical skills are needed to diagnose and fix the Mitsubishi EV system’s required warning message. This article will break down the meaning, causes and recommend professional fixes to help your Mitsubishi EV.
What is Mitsubishi EV System Service Required?
When the Mitsubishi EV system service required comes up, it shows that there are one or more diagnostic codes that the vehicle’s computer has stored. This type of warning message can be tricky because of the various factors that may trigger the warning.
For diagnoses and fixes, you will need professional help and a scan tool to interpret the code and fixes.
In most cases, the Mitsubishi EV system service required warning messages to come with other warning messages. You should pay attention to the other messages as they can help you understand what’s wrong with your EV.
If the EV battery has been identified as causing the Mitsubishi EV system service required, then you know that the warning is serious and should be attended to as soon as possible.
In some cases, the issue is not serious, especially if it does not affect the vehicle’s driving condition. Regardless, when you see the warning message, try to take the car to a professional trained in high voltage systems.
Causes of Mitsubishi EV System Service Required
It could be difficult to determine the exact cause of the Mitsubishi EV system service required. Various problems with the vehicle may trigger the warning message.
However, if your vehicle displays an EV System Service Required warning message, below are some common causes we suspect are wrong:
1. Tire issue
Factors such as the brand, size, and models are important to consider before purchasing a new tire. Many drivers have been having issues after changing their vehicle tires.
The vehicle’s computer system continuously monitors the Tire Wheel Axle Speed difference, and a significant change can cause a deviation from the recognized threshold. Due to the continuous tracking of the vehicle’s wheels’ performance, the computer system stores codes that could be triggered by installing the wrong type of tire.
2. Incorrectly filled AC compressor
The AC compressor must be refilled with oil at the appropriate time. This helps its moving parts, removes heat, and properly seals the compressor. However, filling the AC compressor with the wrong type of oil could be detrimental to its components, like the coil.
3. Overheated PTC heater
As much as the PTC heater serves as an additional heat source for the EV, it could also become an overheater causing its own problem. When the PTC heater gets overheated, the vehicle’s computer system will store this problem as a diagnostic code.
4. Issue with the 12V battery
The 12V battery is a small-capacity battery that keeps the system up and powers some accessories in the EV. Once there is an issue with the EV battery, and the voltage drops to around 10-voltage, it will trigger many warnings and codes in the vehicle. It could also cause the car not to go into ready mode.
5. Fast, rapid charger
Some Chargers can trigger faults in the system, and this is because some charging units work differently when compared to others. The charging unit might not be compatible with your vehicle. Some chargers will not inform the charger to turn after a full charge, while others come with other problems.
When this happens, a series of error codes will come up, which could affect the vehicle’s current condition.
How to fix a Mitsubishi EV System Service Required
Below are ways to remedy a Mitsubishi EV system service-required warning message.
1. Fix the tire issue
If you just changed the tires on your vehicle and the warning message comes up, there is a high chance that the tire is the issue. This means that you have the wrong tire on the vehicle, causing problems with the system.
When faced with this issue, you must change the tire to the specified type recommended by the manufacturer. Check the owner’s manual to get the right tire specification.
2. Change the compressor oil and fix the damaged part
If you have the wrong oil type in the compressor, drain the oil and fill it in with the right oil. Before doing that, you have to ensure that no damage has been to the coil. If there is any damage, have it fixed!
You can drain the compressor by locating the compressor drain plug. By unplugging it, you can eliminate all the bad oil and replace it with a new one.
3. Fix the PTC
If you have damaged the PTC heater, you must have it replaced immediately. To do this, disconnect the PTC from the 12V battery and remove the HV services. Once done with that, disconnect the heater connector from the battery pack. Replace the PTC with a new one.
4. Replace the 12V
If you have issues with the 12V battery always draining, you need to replace the battery. Do not try to manage the battery, as it could further damage the vehicle’s components.
5. Fix issues caused by the fast, rapid charger
Problems that arise from a fast or rapid charger may be tricky to fix. You must take the vehicle to a professional for an in-depth diagnosis and a proper fix.
Final Thoughts
It would be best to have a Mitsubishi EV system service that requires a warning message properly diagnosed and fixed by a professional. This will ensure a proper diagnosis for your vehicle without any issues left unattended. If any trouble code traced to this warning message is not attended to, the warning message will return.
