ABC codes not matching with tech tip

Quick questions about ABS codes. My 92 is posting a 44. When using the tech tip under brakes and suspension it states no output from the left rear. Using the factory manual a 44 code is the right rear and a 48 would be the left rear. I tried to unplug each one but got a new code that was not wheel specific. Sooo any one know which one is right?
