View Full Version : diagnostic port not working
Well it seems that my car's diagnostic port is not working :eek: :mad: . Starting to suspect that this might have something or alot to do with the ICE installation:( :mad:
Are there any precautions to take when replacing the aura HU.
Mine didn't work on the rollers at Stealth. Richard (Revo) said that there are only 5 pins connected and sometimes they fall out of the back.
Funny thing with mine was that I worked with Revo's connector straight afterward.
I sure hope it's a simple problem as the shop guy just told me that there are 3 dangling wires around.
I really hope it's just coincidence that it stopped working or somebroken wire. Otherwise it will be one extremely big pain in the ass to resolve:mad: :mad: .

Whatīs ICE instalation!?
How do you know itīs not working?
Never heard of such a problem before.. :confused:
Was reading in another thread around here that an incorrectly fitted install could put 12v on the k line ( whatever that is )
other than that probably what RB5 said.
Yeah, that was in the Golf Anniversary write up...
That'll be where I saw it then. I couldn't find it anywhere.

I would say it would be the same for the Seat - if you can use diagnostics on the standard headunit in the car then its got a data connection (the K-wire) - have a read of this which explains all
K wire probs (http://www.ross-tech.com/vag-com/aftermarket-radio.html)

Rage,
Did you modify the wiring when you put your new head unit in?
Just wondering if it's something to do when I finally get my Alpine put in.
nope but Clarion mentioned that VAG cars have wierd power connections and you'll need to swap the memory feed for +12V as they are wired backwards in VAG cars.
<Ducks as that goes straight over his head> :confused:
:D
In order for your stereo to remeber its settings i.e. radio stations, disc names, bass/treble etc. it requires a permenant 12v feed from the battery. Seperate from this it usually also gets a 12v accessory feed which only activates when the ignition is turned on. On non-VAG cars installing the stereo ( when equiped with ISO plugs ) is just a plug and play situation.
On VAG cars the accessory wire and the 12v memory wire are swapped over. So when you install your stereo you will find is doesn't remeber anything once its been turned off. The Clarion wiring loom allows for this and allows you to swap them back to international standard. I assume the Alpine would do the same as this is a known problem. You should find an addendum to the install instructions with the stereo.
Ahhh, I see.
I think I need an loom convertor for my Alpine but there's nothing in the manual about reversing things.
Thanks for the info guys, but it seems that the OE plugs have some wires cut off, plus there's a wire loom with nothing connected. This does not look good. The OE wires where not used.
Maybe I'll wake up and this will be just a bad dream....:( :(
Just going to have my dealer figure it out before I do a Rambo on someone.
Gleistung -
ICE is In Car Entertainment.
Chri5B : The loom that came with my alpine didnt have half the wires connected, as well as having the permanent/switched lives the wrong way round. I ended up buying an ISO extension lead and used half of it to replace the ISO plug on the alpine loom - bit of a pain but it meant I could shorten some of the wires, connect up the remaining wires and swap the live connections (not much room behind the HU for all them wires!)

You're not wrong there. And why is the aerial cable so short? I ended up breaking the pin off the middle of my connector and I had to bodge together a new plug and use an adaptor to get back to ISO. Thankfully I have DAB so I don't need it much...
Cheers Dave - did you get one of the Audoleads jobbies from Halfords or somewhere? Don't suppose you can remember the part number?
Which head unit have you got? I've got the 7893R.
Chris.

Even with the toledo big dash, the lack of space behind the HU is notorious. still hoping that my problem can be easily resolved.:( :(
You can get some converters that plug directly into the back of the HU (certainly for kenwoods) which replaces the one that comes in the box, but I couldnt find one for the Alpine. I think I have chucked the package away now, but it was just a straight through ISO plug to ISO socket that I got from halfords. I chopped the power ISO from the Alpine loom and replaced it with the one from the halfords item using crimps.
The problem with this unit (I also have the 7893R :)) is that all the inputs/outputs are on flying leads. Power/speaker ISOs (with a big filter clamped on), pre-amp outputs, aerial connector, cd changer etc. You just have to feed the unwanted connections out of the way, but there is so little room. I even tried swapping the position of the HU and the useless open box underneath but it didnt look very good.
Dont forget you need an aerial amplifier too if you want to pick up decent AM.

Paulo what about previous car inspections ? They had to connect somehow using vag-com like tool to read the dtcs and other data, hadn't they ? :confused:
I understand you haven't visited seat dealer once you swapped the headunit ?
Hope you will get it sorted soon.

My Blaupunkt has sockets for the ISO plugs straight in the back (like the OEM unit). I cut the two power wires in the car loom and crimped in bullet connectors so I could swap them over and back as required.
Dave - many thanks for the info, sounds like a receipe for skinned knuckles and lots of swearing :rolleyes:

Yep, the car had been connected 3 times (30,60, & 90kkm). My local dealer is a very cool guy, so we where working out the software code & ECU # for Richard over at REVO when we found the problem. Looks like one to many cut wires + a disconnected wire from behind the socket (no big deal). I was getting worried though.
If any of you guys do need the blaupunkt catalog with the ISO converters & plugs (some by car model even), just e-mail me and I'll send it out tomorrow. I've got it in *.pdf format a work.

Spaghetti, Alpine style:

:rolleyes:
Your yellow wire and your red wire will need to be swapped over. It looks like its equiped with bullet connectors to do just that.
Red feeds off the iginition, yellow is for 20amps straight from the battery.

Haven't checked specs but I guess that means U've got one with the v12 engine amp "thingy". Something like 55Wx4.
It's not V12 but 4 x 60w with all manner of fancy functions I'll never use :D
for some reason, they didnt connect the control wires into the iso block (for things like dimmer control, telephone mute etc) - my old kenwood loom had these wired in?
My clarion has these wired in as well. Albeit with some bullet connectors so you can disconnect them if you need to.
Actually the wires that where cut had nothing to do with the problem. Had 2 wires broken behind the port. Everything is up and running.
Well, my Alpine head unit is fitted now.
I didn't have any trouble with it - dealer did it for me :D :D
Not sure if my ears or the OE speakers will give up first. Anything above 15/16 on the volume = door shake :rolleyes:
MP3 on CD is such a gadget though. Still going through my first CD in the autochanger which has:
4 REM albums
Nickleback
Linkin Park
Avril Lavigne
Jimmy Eats World
2 Matchbox 20 Albums
A
Coldplay
Dream Theatre
all on one CD :D
The scrolling track name / artist / album display is suitably impressive too :D
Excellent. Sometimes I think I should have gotten a receiver with mp3 playback, not that I dislike the clarion I've got.
As for the shaken have the door dynamtted, you'll be surprised how much better the same setup will sound.
Try get Simon to help as he's already done it. Dounut HiFi:D ;)
you must have compressed them albums quite a lot - I tend to get around 10 on a disc (VBR, but usually around 196kbps).
The scrolling display is quite nice, but my old kenwood unit was nicer as it had dot matrix display rather than alphanumeric of the alpine so was a 'smoother' scroll.
I rip at Near CD-Quality using VBR via Lame & Easy CD-DA Extractor.
Sounds find to my piss poor hearing :D
Play a 'real' CD of one of the albums immediately after the MP3 to see if the uncompressed sound is noticeably more 'open'.
I'm not a Hi-Fi or ICE head (nor anywhere close) and tend to take such descriptions with a pinch of 'w@nker', but in this case I think you'll see what I mean.
