As a vehicle owner, there are always situations where you should be aware of how your car operates to approach the issue most effectively instead of relying everything on the mechanic.
What does the MIL command status fail mean? This is one of the typical matters that require neat attention.
Let’s join us to delve further into this sphere as well as reach out to the most feasible remedies coming into our hands!
What Is MIL?
So, what is MIL status? MIL is a technical term in the automotive aspect, which means Malfunction Indicator Lamp.
In other words, MIL equals a dashboard indicator that illuminates whenever the car’s computer detects something wrong is happening under the car’s hood.
Or worse, there might be an issue regarding faulty spark plugs or the ignition system that could lead to rough idle when the AC is on.
Once you see the light, it usually informs you that you need to bring your car to the third-party service engine and fix it to prevent further run-down and more expensive damage.
This means the moment the lamp starts flashing or blinking, you would have no time to be reluctant but take your car in for maintenance without delay.
Otherwise, the catalytic converter can sustain costly destruction.
So, what is the limit of time that your vehicle can run with the light on?
The answer is roughly longer than a month for a qualified technician to be capable of inspecting and repairing the vehicle.
Exceed that limit; there might be little chance you can have your car fixed as well as earlier.
What Does MIL Command Status Fail Mean?
What does MIL status off mean?
The falling of MIL command status often demonstrates via its abnormal lighting, implying that the system can no longer be working to determine the existence of errors adequately.
Little did you know, MIL status off or on has a lot to do with emission failure in an automobile. There are reasons why this system is also referred to as Maintenance Indication Light.
That explains although such a lamp’s illumination is frequently not a good sign, there are certain points the part just does its job as a general rule.
As such, you will know that your MIL command status has gone wrong once seeing it performs improperly in the cases below.
The two important junctures to lay eyes on are after you turn the ignition key to the 2nd position and following the engine is kicked off.
In these stages, you will need to check whether the yellow Check Engine Light turns on at the first phase and switches off at the latter.
If things do not work out in that order, there might be no doubt that your MIL command status has encountered some technical problem that calls for a reliable auto repair facility.
How To Fix MIL CMD Fail?
To remind you of the MIL CMD’s mission, it is one of the items examined during a vehicle emissions test, a.k.a the Check Engine Light’s functionality.
A faulty circuit, a failing light bulb check portion, a dash bulb, etc., could be to blame if you didn’t see the MIL commanded on when starting.
Luckily, there are ways to help you address such a bother. The best thing is: The process includes a few steps only!
The first thing to do is to check all the fuses under the hood of your car; never overlook any single marked PCM.
Once done, all left to do is merely restart the buddy and see if it can get rid of the problem yet.
A heads-up: Don’t forget to let your MIL be activated in KOEO, a.k.a key on engine off state as well.
There is also a likelihood that the dash bulb lights are where to hold responsibility. Under that circumstance, everything may still function.
The only dilemma is the OBD-II test computer will display MIL-ready status ON all the time.
If your car doesn’t have a computer to inform you of that, you must get that light to illuminate in the KOEO condition.
What Is MIL KOER?
Whenever some related hurdles come into sight, the inspector would have to perform two forms of inspections.
The first is Key-On Engine Off (KOEO), which we have mentioned earlier, and the second is Key-On Engine Running, so-called KOER.
You may find things work out pretty straightforward applying the former. That is also what the majority feel and what we recommend our readers to go for.
However, things go a bit differently when it comes to KOER.
That way, you must first allow the engine to idle after starting it. Next, check to see whether the MIL is on when the engine is running.
The OBD system has decided that a problem has arised with the engine if the MIL illuminates during driving.
In this situation, the computer of the car should have more than one diagnostic trouble code (DTCs).
Is It Safe To Drive With MIL Light On?
Not really. MIL’s role in the check engine light is to display a telltale sign of a problem. This warning light may indicate anything, like a loose fuel cap or a very loud engine knock.
As aforementioned, you can leave it there for a maximum of a month or so, but there are always risks that it will break down in the middle of somewhere anytime during your normal driving.
What Is The Difference Between MIL And DTC?
A DTC, or diagnostic trouble code, is a readiness code check designed to directly identify problems with heavy machinery or what derives from a vehicle manufacturer.
A DTC pinpoints the nature and location of the issue or fault codes, in contrast to the MIL command status off or on, which merely notifies drivers that there is a problem.
How Many Trips Does It Take To Turn Off A MIL?
A trip counter is initiated as soon as the MIL is switched on. After the defect is reported, this keeps a record of the number of trips executed.
The MIL is frequently on its off mode if the PCM doesn’t find a defect in the following three excursions.
You need to track down the causes should the MIL command status fail to function to give response to such a dilemma as soon as possible.
It’s then time for the first round of shooting for it and inspecting your vehicle on your own.
