Does anyone know what this means? In the section where it normally tells you trip info or oil life it's just flashing no.

ezone

No communication, probably the comm bus between modules is down for some reason.
Any other lights flashing on the dash?

What car do you have, specifically?? Year, trim, country?

TreyM

2007 honda civic ex coupe m/t. USA.

ezone

Any other warning lights on the dash flashing or anything?
Do all of the gauges still work?

TreyM

And the check engine, abs, and srs lights are all flashing randomly. Not in any sort of time, just sparactically flashing

TreyM

Yes, all The gauges work.

ezone

Pick a flashing light,
Key off, wait 10 seconds, turn key on (don't start the engine)
count flashes to come up with numbers.
For most of the modules, Long flashes represent 10s digit, short flashes are 1s.

See how many of the lights are flashing fault codes.
See if you can get codes from all flashing lights?

Got a code reader or scanner?

TreyM

I just replaced the throttle body assembly and I was using a snap on solus pro to relearn idle. For some reason ckp relearns fine and I tried relearning idle for about 2 hours just now and idle is still inconsistent, slowly bumping from 900 to about 1800. The only codes present are p0301 misfire cylinder 1 although when I drive (when it's not in limp mode) it drives fine. I will try your key on, count flashes trick shortly.

ezone

Disconnect it then cycle the key. Does the odometer display return to normal?

Scanners can interrupt communication and cause false codes, big time.


Why? (they have been so reliable here, I can only remember having to replace one...and that was on an Accord)

Still have the old one?

Um, does that scanner have any throttle functions?
In ETCS system: TP position check?


For idle....
Tried a "PCM reset" then relearn?
Idle learn isn't done with a scanner.....just wipe memory and let it idle hot for about 10 minutes with NO electrical loads, in park. If the fans run add that time to the 10 minutes.

But it has to be pretty dang close to running right before it can learn idle. If it's surging it usually isn't a learn problem...more like a throttle body reset and minimum air rate learn.

Check if APP sensors are straying or steady? (datalist)

TreyM

So, I unplugged the scan tool and the dash went back to normal. My old throttle body wouldn't hardly open or close so I threw it out. The app sensors were reading very constant. No waivers unless I touched the pedal obviously. And I did the ecm reset prior to relearning idle. Gonna start it now with no scan tool and see what happens

TreyM

Idle is back and the dash is all back to normal. Ezone,you are the man! Thank you.

ezone

So the scanner was causing all the problems? LOL that's great.

TreyM

Yeah, haha extremely ironic. I've never seen a high dollar scan tool cause problems like that. So strange!

ezone

Dealers scanner (HDS/IHDS) can do it too........ the vehicle to PC interface module is usually what causes it when I see it happen


Got your airbag recalls done yet?

TreyM

nope. I really need to but I don't have time or another vehicle. :/

Asasingkiller

How can i find out if the car i have has had its airbags recalled? I wasnt the original owner, its a third hand car.
