DSC/RSC HU/CM INSPECTION

id041800818600

1. Disconnect the DSC/RSC HU/CM connector. (See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)

2. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].)

3. Attach the tester lead to the DSC/RSC HU/CM harness side connector, then inspect voltage, continuity or resistance according to the standard (reference value) on the table.
