Ewen Posted July 21, 2006 Share Posted July 21, 2006 Just had a specialist try to read an error code. There is a problem with my diagnostics port....it doesnt have a TE1 pin (see pics). The guy (who has only seen this a couple of times before on Jap imports) is unaware of anyone who could connect to the port. He also says that its not an OBDII port full stop, and not really an OBDI port either. Anyone come across this, if so, any ideas who could extract an error code using this port ?

Alex Posted July 21, 2006 Share Posted July 21, 2006 What about the one in the cabin? Quote Link to comment Share on other sites More sharing options...
Ewen Posted July 21, 2006 Author Share Posted July 21, 2006 Didnt know there was one in the cabin Alex:( Quote Link to comment Share on other sites More sharing options...
Alex Posted July 21, 2006 Share Posted July 21, 2006 It's under the steering wheel. By your shins. Quote Link to comment Share on other sites More sharing options...
supRo Posted July 21, 2006 Share Posted July 21, 2006 Apparantly some VVTI's have the Pre-VVTI Diagnostic port in the engine bay and as you've said, the TE1 PIN is not connected and the port under the dash is not suitable for the conventional diagnostics machine. Speak to Gaz at Envy as this is what he found on Qaisars Supra when he needed the error codes checked at Japshow. Not sure if Gaz found a way round.

Chris Wilson Posted July 21, 2006 Share Posted July 21, 2006 As I posted the other day, it isn't an OBD port in the accepted and, (I thought),internationally required sense. I have yet to meet anyone I'd believe who has read anyhting useful from it. Another downer for the VVTi's , info availability wise, IMO.

Ewen Posted July 21, 2006 Author Share Posted July 21, 2006 Thanks so far guys. Quote Link to comment Share on other sites More sharing options...
qaisar Posted July 21, 2006 Share Posted July 21, 2006 As Ro said my car is the same, Gaz wasnt able to get a reading from my car from under the dashboard either, but not sure if that is just an issue with my car, something i need to get checked out.

Ewen Posted July 21, 2006 Author Share Posted July 21, 2006 I've actually got three diagnostic ports. One on the engine (minus TE1 connection), a circular one under the dashboard which has various connections including E1 and TE1 BUT has no wires connected to it, and a third, true OBDII port under the dashboard. Ive just come back from the guy after he successfully obtained two Toyota specific error codes. Im going to update the thread linked below to keep all this in one place.... http://www.mkivsupra.net/vbb/showthread.php?t=45814&highlight=TPS So if a mod would like to delete this thread, please do.

Alex Posted July 21, 2006 Share Posted July 21, 2006 Come on Ewen...update your post with the codes already! Quote Link to comment Share on other sites More sharing options...
qaisar Posted July 21, 2006 Share Posted July 21, 2006 this is cool, so there's a third port? Gaz must have connected the machine to the second one with no wires connected to it, whereabouts is the third one, cars at Phoenix right now so i cant check Quote Link to comment Share on other sites More sharing options...
Alex Posted July 21, 2006 Share Posted July 21, 2006 If it's what I think it is then it's right next to the other internal one but it's behind a panel. Quote Link to comment Share on other sites More sharing options...
Thorin Posted July 21, 2006 Share Posted July 21, 2006 If it's what I think it is then it's right next to the other internal one but it's behind a panel. You might have to buy another one Alex, just to check Quote Link to comment Share on other sites More sharing options...
Ewen Posted July 21, 2006 Author Share Posted July 21, 2006 (edited) If it's what I think it is then it's right next to the other internal one but it's behind a panel. On my car, its right next to the bonnet release, clearly marked OBDII...so clearly that I never knew it was there. See pic below...note, it was photoed in a mirror ! You can also see the third circular port which is not connected. Edited July 26, 2009 by Ewen (see edit history) Quote Link to comment Share on other sites More sharing options...
Alex Posted July 21, 2006 Share Posted July 21, 2006 I'd guess that Toyota left the disconnected round port in as it was cheaper than redesigning the cover! Quote Link to comment Share on other sites More sharing options...
Ewen Posted July 21, 2006 Author Share Posted July 21, 2006 You're kidding! I'm gonna give you a big kiss if you've solved the VVTi error code reading problem! Steady now:) Its worth mentioning that this guy Pete actually tried two types of OBDII diagnostics machines on the true OBDII port....the first one (his favorite one) came up with a communication error, the second one (his last-chance saloon one) got straight in there.

Jake Posted July 21, 2006 Share Posted July 21, 2006 Do you need a diag tool to read these codes or can you read it from the flashing dash lights, like we do on the older model Supras? Quote Link to comment Share on other sites More sharing options...
Ewen Posted July 21, 2006 Author Share Posted July 21, 2006 Do you need a diag tool to read these codes or can you read it from the flashing dash lights, like we do on the older model Supras? I asked the guy that question, he said it was feasible (he was well aware of the E1 - TE1 paperclip trick on older ports) but he said there were 'risks' to try it on a OBDII port. He left that one up to me...... Im willing to try it, but I would like to know what harm it could do first ? Also, my ECU is clear of faults at the mo...so the best I will get (if Im brave enough to try) is a steady blink. I assume this will still prove it works..... Unless theres others out there braver than me Quote Link to comment Share on other sites More sharing options...

supRo Posted July 21, 2006 Share Posted July 21, 2006 Is it Foodfreak or Freakins - John who has the blue single tubby Supra from Borehamwood I think? Apparantly he has a Diagnostics reader and has been able to read the codes on a VVTI Quote Link to comment Share on other sites More sharing options...
qaisar Posted July 21, 2006 Share Posted July 21, 2006 yeah Mark was saying foodfreak i think Ro btw how was the drive back home? Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted July 21, 2006 Share Posted July 21, 2006 I didn't realise this was not known to people.
