DSC HU/CM INSPECTION

1. Disconnect the DSC HU/CM connector. (See 04-15-6 DSC HU/CM REMOVAL/INSTALLATION.)
2. Connect the negative battery cable. (See 01-17-2 BATTERY REMOVAL/INSTALLATION[L3 WITH TC].)
3. Attach the tester lead to the DSC HU/CM harness side connector, then inspect voltage, continuity or resistance
according to the standard (reference value) on the table.
