Japanfanatic Posted November 23, 2011 Share Posted November 23, 2011 Hey guys, I´ve got a little problem with my 1993 Supra TT Automatic (j-spec model, bone stock engine and electric). Some days ago I wanted to drive around and realized that the speedo doesn´t work, the odo doesn´t count the kilometers and the o/d-light was flashing. So I started to read out the error code: code 42. After that, I checked the junctions of the SLD and on the board of the speedo, but everything´s fine: After that, I checked every PIN on the odo like the workshop manual says. (maybe not so interesting for you, because it is in German) After we checked PIN 6, we realized, that the voltage doesn´t change. The signal of PIN 6 comes from the PPS-ECU (progressive power-steering) So to be honest I don´t know, what to do now. Where is the PPS ECU sitting? What would you do if you were me? I´m a little bit baffled..... Thanks in advance Andy Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 24, 2011 Share Posted November 24, 2011 You need to see if the speed sensor on the gearbox is giving an output when the back wheels are turning. Link to comment Share on other sites More sharing options...
Japanfanatic Posted November 24, 2011 Author Share Posted November 24, 2011 Speed Sensor is giving a signal. Pin 5 of the odo is receiving this signal. Tested it. That's the issue, we are running out of ideas. Link to comment Share on other sites More sharing options...
