Volvo Truck ABS Trouble Code Help

I just turned off the power from the main switch. Just remove the step panel on the top will be the switch leave it off for 15-20 min.

 

Do you have another picture that shows the wiring tags on these switches. I am trying to figure out if possibly mine are plugged into the wrong switch. I have swapped out all switches with a new one —- still trying to get my TCS light off and one of the switches had been replaced by someone - so there is a chance that if they had multiple switches unplugged that they plugged them in to the wrong switch?
Also is there a reset procedure to make the light go off or will it turn off by itself when the problem is fixed

 

My uphill assist light is also on so not sure if maybe one of these switches might also be tied into the tcs light staying on

 

what codes do you have ?

 

136. 77. 2

 

I've got sid 69 fmi 2 with intermittent TCS and sensor fault light in a 2013 Mack Pinnacle cxu613 that comes up under the ABS fault codes.

Any ideas which sensor to look at?

Same problem,I have 4 sensors,how can I find which need to change?

 

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 !
