DSC HU/CM INSPECTION
id041500801100
1. Disconnect the DSC HU/CM connector. (See DSC HU/CM REMOVAL/INSTALLATION.)
2. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [ZY, Z6].) (See BATTERY REMOVAL/INSTALLATION [LF, L5].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].) (See BATTERY REMOVAL/INSTALLATION [L3 Turbo].) (See BATTERY REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].) (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)
3. Attach the tester lead to the DSC HU/CM wiring harness-side connector and inspect voltage, continuity, or resistance according to the standard (reference) on the table.
