Throttle body. To clean or not?
Hi guys I saw this thread title and immediately thought " I hope he hasn't done it yet". I decided ( god only knows why) to clean my throttle body on my 05' Nissan Maxima ( yes I know not a Lexus), and all I accomplished was destroying the throttle body butterfly fly by wire leaving a gap so it revved close to 2K rpm at idle. To pile on the pain I also decided to "clean" the metal surface on the body itself, massive mistake as all I did was rub off the factory coating ( slightly rough coating before the butterfly). I sincerely hope you haven't done it yet because its a irreversible action especially if you push the butterfly, now I'm assuming Lexus use fly by wire on their throttle bodies but I may be wrong. Best regards Ashley. -

U0101: Lost Communication with TCM on ISF
Hi AUISF33 did you end up fixing your problem? I have almost the same problem. ABS, Power steering & the seat light are all permanently on. Temp gauge doesn’t work, clunky in manual mode and is in limp mode. Checked all the fuses, battery is getting enough voltage, checked all the OBD wires with multimeter all good. Pulled out the ECU to see if anything was faulty and cleaned all the electrical connectors and still no good. Got an auto electrician to have a look and he said not getting any signal from my ABS module that’s why can’t communicate with ECU. He said he needed wiring diagram for the ECU, ABS & Power steering which I got and sent to him but hasn’t returned my calls. Not sure where to go from here, do I get a new ABS module and hopefully fixes my problem? Don’t want to take it to the deal shop cause they will sting me. Would like to fix it myself if I can. -
