ABS Codes C1163, C1102 and C1111 all at once.

Last fall I was driving my 2005 4x4 to work and I noticed the antilock brake module trying to kick in around some corners. After a few minutes of this the ABS, VDC and SLIP lights illuminated. On the way home the lights were out on startup but eventually the same thing happened. This went on for a few days until the system seemed to give up and the lights remained on continuously. Over the winter, I investigated as I had time, cleaning wheel sensors and tracing wires, checking continuity etc. I finally purchased a scan tool which can read ABS codes a few weeks ago and I am getting C1163 (Steering angle sensor safe) C1102 (rear left wheel speed sensor) and C1111 (ABS motor/motor relay). Since it seems unlikely that the vehicle has 3 separate malfunctioning parts all at once, I'm guessing that 1 or 2 of the codes are being triggered by the others. Does anyone know if this is correct? And if so, which code do I start with? The 3 parts associated with these 3 codes are quite expensive and so I don't want to just start replacing them. I know the steering sensor requires Consult to properly diagnose and the speed sensor requires a special tool I do not have. The diagnosis procedure for the C1111 is simple and the result instructs me to replace the abs actuator module but I'm still not convinced this code isnt being thrown by one of the other issues or vice versa. As an extreme DIY, this is driving me crazy so any info or guidance is greatly appreciated!
