I was on my way home from work on a chilly night at about 3am and my slip light came on but my TCS was off. My Z was losing power. I pulled over and let the car idle for a minute and the light never turned off. I always let the car warm to temp before leaving. Don't know what caused this. Turned the car off for a minute and restarted it and everything was ok. Anybody else experience this? Thanks for any help!

 

After you shut it off how much further did you drive and did it turn back on.. I had the same problem and it ended up needing the steering sensor recalibrated..
