I found two plugs on top of what I am assuming is the abs motor and unplugged one of them and the noise stopped.

 

You really need to pull codes out of the abs module and post.

 

Take it in!

 

i agree with hydra, beyond changing sensors the abs module is usually beyond the capabilities (and equipment) of the backyard mechanic

 

Well one can change to module if they want but you have to ensure you are replacing it with the correct configuration hints the 2 wheel or 4 wheel ABS as to what the OEM was set up for. But again, the normal user isn't able to understand most of their braking systems. This is why it would be more beneficial to just bend over and take it in. Please post your results?

 

Ok, here is the abs code they pulled off of it. Code 67 Motor circuit malfunction....Is this the abs pump ???

 

Symptom:
PUMP MOTOR FAULT
When Monitored and Set Condition:
PUMP MOTOR FAULT
When Monitored: Ignition on. The CAB commands the pump on at 20 km/h (12 mph) to
check its operation, if the brake switch is not applied. If the brake is applied, the test will
run at 40 km/h (25 mph). The CAB monitors pump voltage every 7 milliseconds.
Set Condition: The DTC is stored when the CAB detects: 1) Improper voltage decay after
the pump was turned off. 2) Pump not energized by the CAB, but voltage is present for 3.5
seconds. 3) Pump is turned on by the CAB, but without sufficient voltage to operate it.
POSSIBLE CAUSES
CAB - PUMP MOTOR RUNNING CONTINUOUSLY
ABS PUMP MOTOR INTERMITTENT DTC
FUSED B(+) CIRCUIT INTERMITTENTLY SHORTED TO GROUND
FUSED B(+) CIRCUIT SHORTED TO GROUND
CAB - FUSED B(+) CIRCUIT SHORTED TO GROUND
FUSE BLOWN - PUMP MOTOR CIRCUIT
NO B+ SUPPLY TO FUSE
ABS PUMP MOTOR INOPERATIVE
FUSED B(+) CIRCUIT OPEN
GROUND CIRCUIT OPEN
GROUND CIRCUIT HIGH RESISTANCE
CAB - INTERNAL FAULT
TEST ACTION APPLICABILITY

Is the test light on?
All
Yes ® Repair the Fused B(+) circuit short to ground.
Perform ABS VERIFICATION TEST - VER 1.
No ® Go To 6
6 Turn the ignition off.
Remove the ABS PUMP Fuse 8 from the PDC.
The CAB must be connected for the results of this test to be valid.
Using a test light connected to 12 volts, probe the Fused B (+) circuit in the PDC.
Is the test light on?
All
Yes ® Replace the Controller Antilock Brake in accordance with the
Service Information. Refer to the symptom *Replacing the Controller
