Abs/TCS Functional Check

If the ABS/TCS condition is not resolved as a result of the Visual Inspection, the ABS/TCS Functional Check should then be performed. The ABS/TCS Functional Check will then lead to a specific trouble tree chart or test. Several different test methods and various types of diagnostic charts are used. The TECH 1 or Tech II is used extensively at this point. See Fig 1-Fig 5 .
