David P Posted May 6, 2015 Share Posted May 6, 2015 (edited) Have you confirmed there's a signal from buttons to ECU? Was that ECU pin-out PDF diagram useful? Did you check continuity from solenoids to ECU? Have you cleaned the solenoids? Have you checked that the solenoids are all functioning? Did you re-torque the valve-body? These things need to be done before fitting a new filter.Supra_2JZGTE_VVTi_ECU_Pinouts (4).pdf Edited May 6, 2015 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 6, 2015 Share Posted May 6, 2015 Not having (or really wanting.... ) any experience of these, but being mildly interested from the electronics point of view, surely if the car drives fine in auto mode, but the displays go awry and he has issues with using the buttons it won't be a solenoid issue, but possibly a connection issue from the buttons, or an ecu signalling issue that is not telling the ecu he wants button control? Oh for a circuit diagram to look at! Quote Link to comment Share on other sites More sharing options...
TuneR Posted May 6, 2015 Share Posted May 6, 2015 Might be an idea if you could get a loan of a working TTT Supra and you could swap parts like the ECU to see if thats the issue, probably tough though. Quote Link to comment Share on other sites More sharing options...

These things need to be done before fitting a new filter. Checked for continuity: Check Solenoids cleaned: Check Solenoids all Click: Check Valve Body torque checked as per TT ratings: Check It appears that the manual mode has stopped flashing so fingers crossed the issue is solved.. If not I'm going to pass the car to John Hodge to check the ECU wiring. Quote Link to comment Share on other sites More sharing options...

Oh for a circuit diagram to look at! I have 3 different pin diagrams some have the right corresponding colours some do not haha loving life at the minute.. But one diagram seems to match up correctly. Quote Link to comment Share on other sites More sharing options...

Was that pin out ECU PDF the right one? What are "TT ratings" if they are not 7ftlb? Did the bolts move or were they tight enough?

MattP Posted May 10, 2015 Author Share Posted May 10, 2015 Right then so Today I got the New sump filter etc put on and all back together but as I suspected It has not cured the problem. I would like to point out the Car 110% is reading a fault code 76... What the hell is a fault code 76? David P- No I have not I dont have a clue how to do this? I do apparently have a mcahine to do it but lack the knowledge to use it... Quote Link to comment Share on other sites More sharing options...

safcdixon Posted May 10, 2015 Share Posted May 10, 2015 Somebody please help me find out what a code 76 is on a vvti its driving me mad. Have you tryed asking/searching over on supraforums?

j_jza80 Posted May 10, 2015 Share Posted May 10, 2015 There's no point looking on Supra forums, many of them don't believe the tiptronic model exists They never got them in the US, and there is almost no information on there about them. as for the fault code, you could try emailing Toyota. I don't think it is a gearbox mechanical issue though, I think it is an electrical issue. Quote Link to comment Share on other sites More sharing options...

Thats wierd considering the years they were released over there ah well forget what i said then , will the code show on a snap on diagnostic tool?

j_jza80 Posted May 10, 2015 Share Posted May 10, 2015 They didn't get vvti cars at all, even on the 97 onward models. And yes, VVTi's have OBD2 which may show up the fault. Quote Link to comment Share on other sites More sharing options...

MattP Posted May 10, 2015 Author Share Posted May 10, 2015 Hmm, swapped the whole dash for what? (And why....?). Another stock undamaged dash from a equivalent facelift model.. When Jurgen imported this car it had little pin holes on the passenger top piece that's why I swapped. Quote Link to comment Share on other sites More sharing options...
