usually, I find the sensors on the wheels (front) get gunk on them and make it throw the code. Also they can get detached from off roading, or even break the wires. All must work or it will put on the ABS light.
There is also the possibility that one got mashed!
Also make sure the brake fluid is up. if it is low, could be due to low brake pads, or leak. Ckeck lines on right front, as they can wear thru.
Hope you find it and can easily correct the fault.

Yeah mine came on this weekend at Woolys. Probably from the combination of mud on the sensor and having to ride the brakes down the mountain side. I turned it off for about 30 minutes and it never has come back on.
