This is a known problem.
Afaik, Honda Germany is replacing the battery-sensors, since about 50% of them are faulty.

I think there was a problem on some of the early cars. But a car in the error state could be reset by disconnecting the battery, and since it is well publicised I imagine everyone here has already tried these steps or had their sensors replaced. When this fault occurred the battery symbol would appear so it is quite obvious and unrelated to any of the other warning messages

I've just got my Civic 9th gen and been playing around with it and I can't seem to get the stop /start to activate.
If I pull up put it in neutral and apply the hand break all that happens is a symbol "A" with a line through it and a picture off a battery.
Is there something wrong or am I doing something wrong?:confused:

That means the battery is not fully charged, so the system won't activate... Their are several warnings like that for various reasons for why the auto stop won't activate.. Such as ac on full.

A reason this is happening to you maybe that you've only been doing short trips. Give the car a nice run and all should be ok

Thanks Bog,
I did wonder as the car has just been sat on the dealers forecourt and I have only been doing very short trips.
Reading through a few threads it seems very few people bother with it anyway.
I have just been trying all the gadgets and options that the ES has over my old gen 8 SI:)
Probably many more questions to follow;)

The problems are long trips because the battery become fully charged. So, leaving the car stopped for 2-3 days, the battery discharge a little but it's too much for the battery sensor or the software. If I disconnect the battery negative for 4-5 minutes the problem disappear. In November the dealer replaced the battery and until I made a long trip the problem was not showing. Just an info, the 1.8 battery is 45Ah or 60?

Well, I can't tell you much, since I don't own a Civic (yet).
The Problem seems to be, that the battery sensor doen't recognize the batterys charging vlevel, once it has dropped under a certain value and prevents auto start/stop from working even if the battery is fully recharged.
A workaround is to disconnect the negative battery cable for a short time. If the sensor is the reason for the problem, it should start working again for certain time, but will fail again after a couple of months.
The only permanent solution seems to be a new sensor.
I'm not sure if Honda Germany is actually replacing them or if this was just a rumour.

That could also be why the autostop isn't kicking in. Things like my sat-nav and MP3 player draw power from the car's battery, so when they're on, autostop refuses to happen.

Maybe, but I have these things and I also leave my WIFI OBDII Dongle plugged in all the time and it seems to have little affect.

My Auto stop stopped working for a couple of weeks back in early december, but I think it was because it was quite cold here??


From the manual:

Auto idle stop does not activate when:
• The low temperature indicator is on.
• The vehicle comes to a stop again before the vehicle speed reaches 15km/h (9mph) after the engine starts.
• The shift lever is in (R)
• Airflow from the climate control system increases.If you have selected the fan speed manually: The display shows more than five vertical bars ECON mode ON.
• You are not wearing a seat belt.


Auto idle stop may not activate when:
• The climate control system is in use, and there is a significant difference between the set temperature and the actual interior temperature. (ECON mode ON).
• When humidity in the interior is high.
• The vehicle is stopped by braking suddenly

Hye Guys,

My Civic Hybrid 9th gen 2013 idle stop start function doesn't seem to work,i tried everything except for the hard reset, my service centre seems to be a bit clueless on how to rectify this problem. According to them all system is functioning fine except for the idle stop function and according to the computer, there is no error code. My car has been stranded in the service centre for almost 3 weeks now and people from Honda Malaysia HQ has checked the car but without a solution. Is it a common problem with the 9th gen Civic Hybrid? It is a great car but with the idle stop malfuction its not really inspiring confidence for me to use it. Please kindly update me with possible solutions for this problem, perhaps i can help Honda Malaysia to come up with a solution.

Why is it stranded? Does the car not restart automatically after stopping or does not cut the engine at all?

If you turn on the text in the menu it will tell you why it is not stopping each time. I imagine it will either show a thermometer symbol for cold engine or 'A/C' for anything heater related. I hope this helps to clarify

Can you further explain this. My 1.6 diesel is still set as it was from the factory. On cold morns i've noticed the auto stop not operate but knew it was likely down to a cold engine, however i've never noticed the iMID tell me whats happening and why when i come to a halt. How do i get it to do this? Which menu is it under?

When I stand at a local traffic island and the lights change I often hear the sound of engines starting up, some hesitant. Even some newer lorries seem to do this as well.

I think stop/start would annoy me. It must be extra wear and tear on the battery and starter motor ? No wonder the system keeps telling you your battery hasn't got enough charge.

Actually it is not stranded as in it doesn't start. It starts fine, drives fine even the battery charges fine, just that the ilde start function does not work. Honda has checked everything with their fancy computer but they could not find a error code to this date, the car has been in the Service Centre for almost a month with no solution. I have told them about the battery sensor problem but none of them are listening to me. Does it really work guys? changing the battery sensor i mean?? Did your car show any error code??
