1.  Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR 1.5, MZR 1.6].)(See BATTERY REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].)(See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)(See BATTERY REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)(See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)(See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)(See BATTERY REMOVAL/INSTALLATION [MZ-CD 1.6].)

2.  Remove the grove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

3.  Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).

•  If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
―  If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the USB adapter.
