To properly conduct Quick Test Checks an EEC-IV breakout box No. T83L-50-EEC-IV, anti-lock harness adapter No. T90P-50-ALA or equivalent and a digital volt/ohmmeter tool No. 007-00001 or equivalent must be used. This group of tests will lead to specific diagnostic Pinpoint Test that will, in most cases, identify the fault/malfunction. If fault/malfunction is not determined by the Quick Test procedure, use the following Diagnostic Lamp Symptom Chart to identify the proper diagnostic procedure to be conducted.
Refer to anti-lock quick check Figs. 82 and 83, for item to be tested, ignition switch mode position, measurement taken between terminal pin numbers, tester scale/range, volt/ohm specifications and the specific pinpoint test to correct the malfunction.
Refer to DIAGNOSTIC CHARTS for Pinpoint Tests.
