Abs/TCS Functional Check

If the condition is not resolved as a result of the Visual Inspection, the ABS/TCS Functional Check should then be performed. See Fig 1 .

The Functional Check may lead to several different test methods and various types of diagnostic charts. Due to the fact that some trouble codes are set while driving the vehicle, it may be necessary to test drive the vehicle in an attempt to set and display any trouble codes which may be present. Information regarding the test dive procedure, see TEST DRIVING COMPLAINT VEHICLES  .
