DSC HU/CM INSPECTION
id041500801100
1. Disconnect the DSC HU/CM connector. (See DSC HU/CM REMOVAL/INSTALLATION.)
2. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)
3. Attach the tester lead to the DSC HU/CM wiring harness-side connector and inspect the voltage, continuity, or resistance according to the standard (reference) on the table.
