1.Disconnect the DSC HU/CM connector. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D.].)(See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
2.Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L3 Turbo].) (See BATTERY REMOVAL/INSTALLATION [L5].) (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)
3.Attach the tester lead to the DSC HU/CM wiring harness-side connector, then inspect voltage, continuity or resistance according to the standard (reference value) on the table.
