	Note: It this procedure was not successful verify the alignment is within specifications. Although the difference between the right and left end stops needs to be less than 20°, the actual lock-to-lock G85 reading should be within 8° on a vehicle in proper working condition. A significant discrepancy due to collision repairs will prevent the steering limit end stops from learning.		Note: It this procedure was not successful verify the alignment is within specifications.
