I pulled my abs codes this morning and got a 21 and 61. Has anyone had these codes before? Thanks.
 
Check this link to find out what the codes mean and more:

21
Main Valve (Disconnect main 2 Pin Plug on Hydraulic Actuator Assembly & measure resistance. 2 to 5.5 Ohms, service cable harness, any other reading replace Actuation Assembly)
61
Fluid Level Indicator Circuit (FLI)and Pressure Warning Switch (PWS) Circuit (For FLI disconnect 5 pin connector on fluid reservoir measure pin 1 & 2 for resistance > 2 ohms replace indicator, For PWS disconnect Pressure Switch connector measure pins 3 & 5 should have a short if not replace Pressure Switch FOR PWS CHECK SYSTEM MUST BE PRESSURIZED)

Hmm, did you check your brake fluid?
 
One time the fluid ran very low because of a pressure switch in the proportioning valve started leaking. I fixed that Do you thing a pressure warning switch would fix it?
 
Nope. I'm not saying because I don't know.

Just giving you the info and some ideas. I don't know for sure.

Did you bleed the master cylinder after this low fluid event? You could have air stuck in the system.
