Hello,

Do you know if there is any obd2 interface on the new civic 5dr and where it is located???? :?:

Thanx

I seem to remember reading somewhere that they are located under the driver side dash, though I have to admit I've never looked.

I guess it must be somewhere pretty accessible for the technicians to hook up their diagnostic kit.

...that wasn't much help really was it! I'll take a peek later if I get a chance.

Under the dash near to centre console, pannel under steering wheel needs to be removed.

I got at mine straight away, but couldn't get anything interesting out of the OBD2. I was using a VAGCOM cable, so a proper generic cable may do better (I don't have one).

Audi style VAGCOM Pottsy?

Cos if so, I'll ditch mine :(


Does possibly bode well for playing with things in the future tho :D

obd interface

Thanks for your replies guys,

I will try to have a look and take photos of the socket if possible.

If you have more info about software or hardware (e.g.can bus) that can work with the car please post.

TT,

I think mine is a Twin USB, but yes, they're all the same (Audi / VW etc). We need a Honda version of Uwe Ross - there is a commercial equivalent for Honda, but it costs thousands. :(

LOL - mines an old serial port version (which I've even got a knackered old laptop which still has a serial port just to use it with!)

Hopefully RossTech will get on the case soon...

SOrry to sound stupid, but i am guessing your talking about the ECU?

I am most likely mis-understanding what the hell this thing is.

What information can you get out of it anyway?

The ODBC2 port on the civic is a bit of an unkown at the moment, so I can only go on what you could get at on the TT which had the same style of port.

Basically, yes, you can get at the ECU - for example Revo (and others) can upload remaps directly via the port

However, it's a lot more than that too :D

On the TT you could:
download any faults that had been recorded from any of the car's sensors
set things like auto locking of the doors
enable the alarm beep when locking the car
change if the dash illumination came on with ignition or with the headlights
set it so that single press of remote unlocked driver door, double press unlocks passenger door

and probably a bunch more stuff that I've forgotten about :D :oops:

ummm, sounds interesting.

What is needed for this then?

Obviously, i wouldn't want to change stuff, but its an interesting gadget to know and have just in case.

I have a laptop which has a serial port on.

you need 3 items to get this to work

1) ODBC lead - old ones came with serial interface, newest ones are USB
2) laptop with correct port for above
3) RossTech (or similar) software which can interpret (and modify) data from for port

Pottsy has the USB version of the lead, and a laptop
I have the serial version of the lead, and a laptop

But neither of us have the software to go with it :(

I've got a version of the software that interepts Audi codes, not sure which version Pottsy has, but neither speak Honda :(

In theory, there is supposed to be a standard which all car manufacturers stick to - like code '1234' means 'misfire on plug 1'
But there are a whole bunch of codes which in the standard were 'allowed' to be used for 'special' things (like, I dunno, 'LED courtesy light failure') that wouldn't be generic across all cars

In practise, they all tend to use these 'special' codes for pretty much anything and everything, so the software has to be set up / designed for each car

PS

to do that requires an in depth knowledge of what Honda designed each code to mean.

Randomly changing the codes on the car can lead to all sorts of problems!


Some might argue that by not publishing the codes, Honda are preventing non-Honda garages from servicing your Civic - this is a long running argument against all the major manufacturers which isn't showing any signs of stopping :?

would ANY obd 2 cable do?

Done a search on ebay, and get a few hits. All connectors the same? (whatever manufacturer???)

Then software, how would i be able to make use of it with my honda?

from my limited knowledge - yes - and no...

The ODBCII connector itself is an inductry standard.

And I think this also includes definitions of what each connector pin does.


However, not all leads are the same.

older ones end in a serial port connector, others a USB one

USB ones are by definition more complex, and therefore more expensive - but will fit any USB equiped laptop (ie most if not all recent ones)
Serial are cheaper - but you need a laptop with a serial port - which are difficult to find.


Once you have a cable - RossTech ones where the boys to go for in the Audi / VW world, not sure but guessing the same holds true for Honda - you need the software.

We've already discussed that VAGTech software (again, designed for Audi / VW) doesn't interpret Honda stuff, but yet to find something that does :(

I cam close last week at the RR session - guy there had some generic (and very expensive!) software that may have done the trick - but his laptop was having a sulk and refusing to recognise his ODBCII cable :(


Would have been good - but not too relevant unless you want to invest big bucks :(

Try to use the software Scantool.net, get it here -> www.scantool.net its freeware! There you can also find a link-list of other OBD-2-software (free, share and commercial)

The adaptor should have the ability to detect more protocols, like ISO 9141-2, ISO 14230-4... at least CAN! Like AGV4000-based or with ELM327... i have two (AGV4000 and ELM327, just be on the right side, because some software need ELM327 or AGV4000)

There is a list, where you can look after if your car could be read out with OBD-2-adaptors http://blafusel.de/misc/obd2_scanned.php there seems a little chance for older OBD-2-adaptors like ELM323 to read out Honda...

Good luck! I can't test it, because still waiting for my Civic ;-)
