I got 2007 Volvo VNL with Cummins CM870. Traction control never worked when I bought it used. Was at the mechanic couple of months ago doing some work on truck and asked for checking on it. He said the sensor was unplugged, he just plugged it in and the light went away. After I left his shop abs and traction control lights came back on on the dash. Didn't have time to go back and fix it, so I was driving it like that for a while. Then, my drive axle broke down and I had it replaced. Yesterday I found wheel seal leaking and the truck was shaking up, so I went to the shop to look at it. Turns out it was a bad front hub and bearings which got replaced. As soon as I got the truck back i noticed that my abs light went off , so as TCS light. But when I started to drive, TCS system engaged right away causing my truck to stop. So the maximum speed I can drive right now is 5-10 mph. The guy I bought the truck from said that he was trying to fix the TCS system and mechanic told him that it will be around 5K to fix it, so he asked them to simply disconnect the sensor so he can drive without it. He have no idea what the problem was.
I really want to fix it in the future, however I'm loaded and now just need to deliver the load asap, so I want to ask if anyone know how to manually disable TCS system. I can't disable it with the switch on the dashboard.
Thank you.

If your axle broke , you are lucky to be ok, be careful could have hurt yourself and people around you. This is the risk of driving old high mileage truck, I had tcs fault few years ago on my last truck well over million miles, took it in a good shop, they inspected measures the axle, and found bearing excessive movement spinning and chewing axle spindle . Soo, they couldn't tighten the bearing and ordered these new axle housings new bearings, but was more expensive solution .You can call axle surgeons to inspect it, or similar axle repair services and weld new spindles if needed perhaps new bearings,it cost about 4-5000$ for all 4 drive axle spindles. I wouldn't drive it like this , don't ignore tcs faults , can indicate one wheel is spinning at a rate it shouldn't, yes most of the time are glitches bad abs sensor wires but can signal loose bearing or something more sinister and dangerous at the end of the axle/hub.
