Good evening and thank you for inquiring with JustAnswer, my name is Dustin and i will be the technician assisting you today.

There are numerous reasons why your ABS light could have came on, see chart below:

Diagnostic Trouble Code (DTC) Index

DTC	Concern	Sets At	Pinpoint Test
B1342	Anti-Lock Electronic Control Module Failure	Key On	Replace Anti-Lock Electronic Control Module
C1101	Intermittent Valve Failure	Key On	A
C1185	ABS Main Relay Output Circuit Failure	Key On	B
B1317	Battery Voltage High	Key On	C
B1318	Battery Voltage Low	Key On	D
C1198	LF ISO Valve Coil Circuit Failure	Key On	E
C1194	LF Dump Valve Coil Circuit Failure	Key On	E
C1214	RF ISO Valve Coil Circuit Failure	Key On	E
C1210	RF Dump Valve Coil Circuit Failure	Key On	E
C1206	Rear ISO Valve Coil Circuit Failure	Key On	E
C1202	Rear Dump Valve Coil Circuit Failure	Key On	E
C1155	LF Brake Anti-Lock Sensor Input Circuit Failure	Key On	F
C1145	RF Brake Anti-Lock Sensor Input Circuit Failure	Key On	F
C1230	Rear Brake Anti-Lock Sensor Input Circuit Failure	Key On	F
C1158	LF Brake Anti-Lock Sensor Coherency Fault	40 km/h (25 mph)	G
C1258	LF Brake Anti-Lock Speed Sensor Wheel Speed Comparison Fault	19 km/h (12 mph)	G
C1233	LF Brake Anti-Lock Sensor Input Missing (Long Term)	>2 Min	G
C1148	RF Brake Anti-Lock Sensor Coherency Fault	40 km/h (25 mph)	G
C1259	RF Brake Anti-Lock Sensor Wheel Speed Comparison Fault	19 km/h (12 mph)	G
C1234	RF Brake Anti-Lock Sensor Input Missing (Long Term)	>2 Min	G
C1229	Rear Brake Anti-Lock Sensor Coherency Fault	40 km/h (25 mph)	G
C1260	Rear Brake Anti-Lock Sensor Wheel Speed Comparison Fault	19 km/h (12 mph)	G
C1237	Rear Brake Anti-Lock Sensor Input Missing (Long Term)	>2 Min	G
C1096	ABS Pump Motor Triggered But Did Not Run	7 km/h (4 mph)	J
C1095	ABS Pump Motor Running but Not Triggered	Key ON	K
C1102	G-Switch Circuit Failure	-	M

As you can see there are several different components that could be at fault. I would suggest having the vehicle's ABS module scanned for codes and once the code is retrieved referr to the chart above to identify the fault. Most likely it is the rear axle speed sensor as these are the usual culprit at about 80% of the time.
