Hybrid Drive Motor, HSG, Electric A/C Compressor, Low DC/DC Converter
(LDC), Power Cable, Electric Compressor etc.
1.
Turn the ignition switch OFF and disconnect the auxiliary 12V battery negative (-) terminal.

Remove the safety plug.
(1)
Remove the safety plug cover (A).
(2)
Unfasten the hook (A) and then remove the safety plug (C) by pulling the lever (B) to the direction of arrow.
3.
Wait for more than 5 minutes so that the capacitor in the high voltage system can be fully discharged.
4.
Measure the voltage between the inverter terminals to check that the capacitor in the inverter is discharged completely
(1)
Remove air cleaner assembly and air duct.(Refer to Engine Mechanical System – “Air Cleaner”)
(2)
Disconnect the inverter power cable (A).
Disconnect the inverter power cable as the procedures below.
(3)
Measure the voltage between the inverter (+) terminal and the inverter (-) terminal.
Less than 30V : High voltage circuit properly shut
More than 30V : Faulty on high voltage circuit
If measured more than 30V, check if the safety plug is
removed completely.If measured more than 30V despite the safety plug is
removed, it can be serious problems on the high voltage circuit. In this
case, check DTC and never touch on the high voltage system.
