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

Can you explain what did you change? Please

 

Since the steering wheel was not straight, the sensor was reading it incorrectly and was showing the tcs light, so to make it straight, i disconnect the steering column from the steering gearbox and turned the steering wheel until the volvo sign was horizontal. Connected the column again to the gearbox and to reset the sensor, had to be done thru, i thing bendix software, that i do not have so i went to the shop and they did that for me.

 

Hello everyone!
I'm in need of help in regards the TCS and ABS ( on the truck), please.
The codes that I got on the computer are in the Brake ECU tab:

MID 136 SID 89 FMI 2
MID 136 SID 4 FMI 14

My unit it's a 2012 Volvo vnl 670 ,Cummins isx ,13 speed.
Vin CN 553443
So the TCS light in the cluster it's solid ON, the switch on the dashboard it doesn't do anything if turned on/off.
It started to be like this ,ON ,since I tried to enter the shop where the ground level was different, so I switched ON the front axle switch in order to move .Since then the TCS stayed on. While trying to switch it off from the button it doesn't do anything.
I greatly appreciate your time and expertise into all your answers posted above. Hope you can help me.

Thanks allot !
