Functional Tests (Abnormally Operating System)

If system fails in the preceding tests, utilize the two sets of FUNCTIONAL TESTS (Oldsmobile and Toronado have different tests) and the accompanying electrical and vacuum check charts to assist in testing the system. It is important to remember that at the transducer, the lower the voltage, the higher the vacuum, and the higher the voltage, the lower the vacuum. Many of the functional tests can be performed without using Tester J-22368.
