TCS light - stays on --> Volvo 2012 - 670

My truck is an '01, my light comes on when I start the truck so I just push the TCS button and it goes away.

 

Does it give any codes with it?

 

I got the same issue. Volvo 2011 w cummins isx engine. TCS light came on and never went off. It shows the code:
1. MID 136 SID 77 fmi 2
Anyone has an idea ? Some ppl say it’s the air pressure sensor. I also noticed when i turn my key igniton on and my truck do all the check i cant hear air like it was supposed to release. Please help!
Last time i got this light on my truck, my truck got on fire and my drive wheels fell off.

 

I have the same issue, TCS light on, no faulty codes, Volvo 2008.
Did you fix the problem? If so, what was it?
Thanks

I saw an International truck that had the same problem - TCS light on with no code - and it ultimately turned out to be a rub in one of the wires at the back of the dash. Please let us know if you get it resolved.

 

It was the sensor in steering wheel. I replaced the steering column, and in the proces of the installation, the steering wheel was about 90 degree crooked than is supposed to be, i noticed it when i took the test drive. At the same time i got the tcs light on. After the test drive i straighten the steering wheel but the light was stil on, so i went to the shop where they reset the sensor inside the steering wheel, and voila, no more tcs light and no $100 bucks in my pocket. #$@#~%$ volvo.

 

I’ve TCS on in my Volvo 670(2014).
Anyone fixed???
