Hi all,

I'm new here - I just picked up a 2006 1.8 i-VTEC Honda Civic EX last week, and enjoying it so far! Mileage is pretty high at 145k, but from what I hear, that should be no problem *fingers crossed*!

Anyway, I seem to have a problem which I thought was normal. When I press the 'Engine Start' button and the engine starts, there is a ding and a big yellow exclamation mark shows up on the dashboard computer, but after about 1 second goes out.

Sometimes, just before this, there is an Airbag symbol that shows up really quickly (before it turns into the exclamation mark).

After about 1-2 seconds when they go out, that's it, there's no warning lights etc, so not sure why this happens just at engine start up.

Any idea's? The attached shows the exclamation mark (can't seem to be quick enough to capture the airbag symbol).

Thanks all!
John.

Does it come back when driving at all?

You got access to an ODB reader?
Thanks for the reply.

Nope - literally just for about 1 or 2 seconds after the engine starts, nothing after that.

Don't have access to a ODB reader - but do you think it's worth trying to get one?

Thanks
John.

Thanks - will give it a try! Hopefully it can pick something up, but wasn't too sure as it turns off straight away :/ .

Hello,

I actually managed to find a ODB reader (completely forgot I even had it!).

I did the scan, and there was 1 stored code:
P250E - Engine Oil Level Sensor Circuit Intermittent / Erratic.

However, I cleared the code, drove for a while, re-checked and no faults. Not sure why the engine light didn't show for this stored code - might just be an old code that wasn't cleared etc?

But I still get the same problem with the exclamation mark on engine start up - don't think it is picking up anything for this :( .

Thanks
John.

it might be a tired battery issue
when you press the start button the battery voltage could be being dragged down enough to upset the ECU making it throw odd errors up
once the car starts and the alternator starts putting charge back into the battery the faults clear

it's quite well known that when the battery is getting past it's best it can throw all sorts of warning lights up

check your battery voltage first thing in the morning before you start the car it should read at least 12.6 volts
if the battery voltage looks ok check the terminals are tight and check the earth straps going to the bodywork / engine are tight and free from corrosion

if there is a cell failing in the battery it will drag the cranking voltage right down but there might be still enough juice to turn the engine over and start the car

Is it possibly because the Vehicle Stability Assist has been disabled?
You could ensure it is on by pressing and holding the button, I think it's on the right of the dash if memory serves from when I had an 8G. I only suggest that as I can see the VSA light illuminated, along with the exclamation mark.

don't think you can disable fully for the vsa think you need to press the button after starting up each time
but the light is on also is the top light abs ?
basic obd readers wont read abs and airbag codes
you need a more advanced scanner for that but can still be bought

what are are you someone local to you on here might have suitable code reader

Hi all,

Thank you all for your kind help. I took my car to Halfords for a battery check, and they said the battery was good and reading 230. However I told them to go ahead and change the battery anyway, and that has seemed to fix it! No more 'ding' and warning symbols showing on the computer on engine start up.

Thanks once again!
John

A few people have had this myself included on funnily enough 06 plates, mine hasn't done it now for nearly a year. My advice just ignore it, it seems the system throws a hissy fit it something doesn't add up like a voltage drop/spike etc. I also changed battery from oem to bosch and it went away for a while then came back, last year I went back to a new oem battery and I don't think it's happend since. I also did disconnect the bluetooth module on the a pillar if yours has one incase it was a drain, I don't use it anyway.


I too had checked basic codes plus DTC and nothing ever showed up.
