Black_Supra Posted October 25, 2018 Share Posted October 25, 2018 (edited) Hey guys, last year i had no Problems with the car. In the winter i changed the whole speedo Cluster from TRD to a OEM one. I did nothing further to the car so just to let you know ... The car is a Facelift TT6 one. When i started the car this year the TRC warning light startet to flash on and off. The whole time, it doesn`t disappear. The TRC isn`t working. Furthermore the red warning light in the middle of the speedo pops up when i drive over 60 mph and it stays until i turn the car off. I don`t know if the TRC failure correlates to the warning light failure but this seems strange to me. Maybe these are two different failures but I´m not sure. I already readout the error memory with a paperclip but no errors were saved. I realized, that the TRC stepper motor makes a "click" noise around 25-30 times when i start the car with a break between each "click" of around 1-2 seconds. Anybody knows what this could be? A broken ABS sensor or a bad stepper motor or potentiometer at the TB? thanks in advance Edited October 25, 2018 by Black_Supra (see edit history) Link to comment Share on other sites More sharing options...
Swampy442 Posted October 25, 2018 Share Posted October 25, 2018 if you pull the error codes that will give you a rough idea what's going on. If it was ABS Im sure it would be pretty much instantly as soon as you started driving Link to comment Share on other sites More sharing options...
Scooter Posted October 25, 2018 Share Posted October 25, 2018 55mph is when the active spoiler deploys, do you have/did the car used to have one? Only an idea - - - Updated - - - When you say facelift and stepper motors etc, is your car a VVTI? Link to comment Share on other sites More sharing options...

Black_Supra Posted November 5, 2018 Author Share Posted November 5, 2018 I checked the wiring again. Still got the active aero Switch in but i don`t have the aero lip. The Switch wasn`t connected - i connected it but no Change. Still got at 100 kmh (around 60 mph) the red light flashing and the TRC doesn`t work. It flashes up every 2-3 seconds.
