ECT/PWR button doesnt seem to work
The ECT/PWR button doesnt seem to have any effect on my car. When i press the button the light does not come on the dash either, the same for the VSC light.
I have pulled the gear surround off and checked to make sure they are all plugged in which they are (heated seats work).
Any ideas? Are there any fuses anywhere?
Its a GS430 btw.

Broken wheel speed sensor wire. Did you recently do suspension work? Did you run over something? Check fuses first. Also the led light that eliminates the switches could be bad. Take off on a nice level road at part throttle and notice the shift rpm for each gear. Go back to same spot and turn on ect button, take off in the exact same manner noticing the rpm each shift occurs. Is the rpm higher with ect switch on? If it is ect is working. Now do the same with snow on. It should change at lower rpm and feel like a loss of power, if so it's working. Slam on your brakes, is abs working? Then your sensor cables are ok. Turn corner very fast, do you hear a beeping sound and is your power attenuated? Then VSC is working. Push VSC switch once. Turn corner fast. Does your tail swing out, no power attenuation, no beeping then VSC switch is working. Search for how to fix led lighting if everything works. There is diy on fixing the lighting somewhere on this forum

My mate plugged in a scanner and it came up with error C1336 - Zero Point Calibration for Deceleration Sensor Undone.
I tried the jumper fix loads of times and it just wont get rid of it. Is there are fuse for the YAW sensor anywhere? I have checked all the fuse boxes i can find (two in footwells 3 in engine bay) and cant find one that jumps out at me.
Sounds like s bad sensor. Do a search for that error code
