Component Tests

Components are tested with related circuit. See DIAGNOSTIC TESTS . ABS actuator/ECU assembly values can be measured using Toyota hand-held tester and breakout box. ABS circuits and harness can also be tested by backprobing ABS actuator/ECU assembly 24-pin harness connector and comparing measured voltages with ABS actuator/ECU assembly standard values chart. See Fig 1.
