Regular car maintenance is essential for the smooth functioning and longevity of the vehicle. The maintenance required light is a helpful reminder that it’s time to schedule a check-up to ensure your car keeps running as smoothly as possible. When you turn on the ignition, the light flashes for a few seconds, and then it goes away.

However, if it keeps flashing, that is a sign that it requires attention. Ignoring the light can cause complications that could lead to more costly repairs down the line. This article covers the reasons behind the maintenance required light flashing when car starts and what to do to keep your car in tip-top condition.

Common Reasons The Light Comes On

Lack Of Regular Maintenance

The maintenance required light indicates the need for servicing your vehicle. However, a lack of regular maintenance could be the reason the light comes on in the first place. Here are some key points to consider:

  • The maintenance required light may come on if you fail to replace the air filter as per the manufacturer’s instructions.
  • The light could indicate that you need to replace the fuel filter or you haven’t serviced the transmission fluid.
  • Your vehicle might require new spark plugs, or the timing belt has worn out.

Low Oil Levels

Another common reason the maintenance required light could come on is low oil levels. Here are some key points to note:

  • Low oil levels can cause severe engine damage, and it’s essential to check the oil level regularly.
  • If your vehicle uses a thin oil grade, it may burn quickly, leading to low oil levels.
  • There could be a leak in your engine oil, causing oil to escape and your oil level to drop.

A Malfunctioning Battery

A malfunctioning battery can cause the maintenance required light to come on. Here are some essential points to consider:

  • Your battery is responsible for powering the electronics in your vehicle, and it needs to be in good condition.
  • A malfunctioning battery could cause electrical surges that damage your vehicle’s components, leading to the light coming on.
  • You should ensure that your battery terminals are free from corrosion and tighten to avoid connectivity issues.

Worn-Out Spark Plugs

Worn-out spark plugs could be another reason why your maintenance required light comes on. Here are some essential points to note:

  • Spark plugs play a crucial role in the combustion process, and they wear out with time.
  • If they are faulty, they could cause your vehicle to misfire, leading to the light illuminating.
  • You should ensure that the spark plugs are inspected and replaced as per the manufacturer’s recommendations.

Other Reasons For The Light To Come On

Apart from the above reasons, several other factors could cause the maintenance required light to come on. Here are some essential points to consider:

  • Your vehicle’s emissions control system could be faulty, leading to higher emissions and the light coming on.
  • If your gas cap is loose, it could cause a drop in pressure in the fuel system, leading to an illuminated light.
  • Faulty sensors or onboard computers could also be the reason why the maintenance required light comes on.

The maintenance required light is an essential indicator of your vehicle’s health. You need to take it seriously and troubleshoot it promptly. Regular maintenance, checking oil levels, and keeping your battery in good condition are excellent ways to prevent the light from coming on.

Steps To Troubleshoot The Maintenance Required Light

Maintenance Required Light: Troubleshoot With These Tips

When you see the maintenance required light turn on in your car, it can be frustrating to figure out what the problem is. Fortunately, there are some easy steps you can take to troubleshoot the issue. We’ll go through the different ways to troubleshoot your car’s maintenance required light, so you can identify the problem and fix it quickly.

Step 1: Check The Manual

When you notice the maintenance required light turn on, the first thing you should do is check your car’s manual. The manual will give you specific instructions on how to deal with any warning lights that appear on the dashboard.

Make sure to follow the instructions carefully and check if there are any service codes that correspond to the maintenance required light.

Step 2: Inspect The Oil Level

The most common reason for the maintenance required light turning on is that the oil needs to be changed. Check the oil level to see if it’s low, and if it is, top it up with the recommended type of oil for your car.

If the oil level is not low, you may need to change the oil altogether. Follow the recommended oil change interval in your car’s manual to avoid the maintenance required light from coming on again.

Step 3: Check The Air Filter

The air filter in your car can get clogged over time, which can cause the maintenance required light to come on. Check the air filter to see if it’s dirty. If it is, replace it with a new one. A dirty air filter can also cause your car to lose power and fuel efficiency, so make sure to replace it regularly.

Step 4: Inspect The Battery

A weak battery can cause the maintenance required light to come on. Check the battery to see if it needs to be charged or replaced. If the battery is fine, make sure the connections are clean and tight. Loose or corroded connections can cause your car’s electrical system to malfunction and trigger the maintenance required light.

Step 5: Check The Spark Plugs

Worn out or dirty spark plugs can cause your car’s engine to misfire, which can trigger the maintenance required light. Inspect the spark plugs to see if they need to be cleaned or replaced. Follow your car’s manual to ensure that you’re using the right spark plug for your vehicle.

Step 6: Consult A Mechanic

If you’ve gone through all the previous steps and the maintenance required light is still on, it’s time to consult a mechanic. They’ll be able to diagnose the problem and provide you with a solution. Make sure to explain what you’ve done so far to troubleshoot the issue.

By following these simple steps, you can avoid expensive repairs and keep your car running smoothly. The maintenance required light doesn’t have to be a hassle as long as you take care of your car properly.

How To Reset The Maintenance Required Light

If you’re like most drivers, the sight of the maintenance required light popping up on your dashboard can be a tad unnerving. Luckily, resetting the light is a relatively easy task. Here’s how you can do it yourself with just a few simple steps.

Step 1: Turn Off The Engine

The first step is to turn off the engine of your car and make sure the headlights and all other electrical accessories are switched off.

Step 2: Press And Hold The Trip Button

Locate the trip button on your dashboard and press and hold it down. You’ll want to keep the button firmly held down for the next few steps.

Step 3: Turn The Key To The On Position

While still holding the trip button, turn your car key to the on position (but not to the position where you start the engine).

Step 4: Release The Trip Button

Once the dashboard lights come on, you can safely release the trip button.

Step 5: Press The Button Again

Press the trip button once again and keep it held down for about ten seconds or until the light resets. If the light doesn’t reset, repeat the process or consult your car’s manual.

Step 6: Turn The Key Off

Finally, turn the key to the off position and wait a few seconds before starting your car’s engine. The maintenance required light should now be reset.

Now that you know how to reset the maintenance required light, you can easily take care of this task yourself instead of needing to rely on a mechanic. Remember that regular maintenance is key to keeping your car running smoothly and ensuring it lasts for years to come.
