Why do you see this error message in your Honda?
Sometimes, drivers suppose that they see this message just because they turned off the idle stop system before. But no, in this case, the "Auto Engine Idle Stop System Off" message will come up and the vehicle won't disturb you with any "Problem" messages.
One of the worst things is that when you go to a Honda dealer, the guys will just try to explain to you that it's OK. Honda hasn't gathered enough information about this problem, so there is no instruction on what to do in this case. Dealers just can't do anything but use computer diagnostics and see no fault codes.
Here's why the problem may appear:
- the system is malfunctioning because one of the main components of the auto engine idle stop system is out of order;
- the system failed to stop the engine once you stop your vehicle, the engine keeps working although it should have stopped;
- the battery is discharged and the vehicle can't turn off the engine because there is a risk of a bad start after this;
- something is wrong with the way you are driving your vehicle - for example, the seatbelts aren't fastened;
- there is some other reason why your Honda can't turn off the engine and needs to send this bad problem message.
Usually, when the Auto Engine Idle Stop System Problem message appears, the start-stop system doesn't work and can't be applied even if you push the special button. It means that the vehicle doesn't get the chance to safely turn off and turn on the engine automatically.
Of course, the problem can be bad. But in most cases, it's about some small issue that is easily solved. We've made examples of problems your Honda may have faced. Let's discuss what you can do.
