All the special lights on dash code C1246

2018 tundra with 169K miles and finally hit with all the special lights on the dash, don’t tow at all either.

I've been trying to read through multiple threads about this, but for majority of the cases mines does not show a 4Hi/4LO and ABS light on. Also the truck seems to drive and operate normal. Ran techstream and was showing a history of Fault in Master Cylinder Pressure Sensor (ABS module)?

I do not feel any change in my brakes when braking. Should I go ahead and get a new ABS module?

majority of the threads I’ve gone through somewhat identical to this were claiming ABS/Speed Sensor… I’ve pulled and checked all 4 sensors and noticed three looks normal except for the driver rear which looked like it had orange/brown residue on it instead of the white grease like the rest. Any insights?

Thanks in advance!
