93.5 G20 ABS,SRS and no cruise problem ,related?

[jcmurp]

Have a 1993.5 G20 Heres the problem,I have checked all fuses and they are fine,However the car has the ABS light on,The SRS airbag light flashes (7) and the cruise don't work.So my question is are they related.I would or could see that 1. Antilock brake wheel sensor monitors the speed of the wheels (no signal,no abs)2. Airbag gets or needs speed input for deployment decision(no abs sensor on left front wheel no airbag speed input)3. Cruise needs input speed (again no abs no speed input)So my question would be are they linked together? and how would you check the abs sensor any opinions or input appreciatedThe theory justed seemed feasable
