JUNCTION BOX No.3 INSPECTION

id300400000900

Warning

<<High voltage>>

•  If the necessary measures are not taken before servicing an electric vehicle, it could cause electrical shock and result in serious injury or, in the worst case, death. Before servicing the electric vehicle, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and implement the necessary measures. (See HIGH VOLTAGE SERVICE CAUTIONS.)

High Voltage Part Inspection And Removal/Installation Notes

Warning

<<High voltage>>

•  If necessary measures such as wearing the correct protective gear are not taken when inspecting or removing/installing the high voltage parts, it could cause electrical shock and result in serious injury or, in the worst case, death.

•  Before inspecting or removing/installing the high voltage parts, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and [High Voltage Part Inspection and Removal/Installation Notes] of the high voltage system service cautions and implement the necessary measures and preparations. (See HIGH VOLTAGE SERVICE CAUTIONS.) (See HIGH VOLTAGE SYSTEM SERVICE CAUTIONS.)

Insulation Resistance Inspection

1.  Wear insulating gloves and remove the service plug.

(See SERVICE PLUG REMOVAL/INSTALLATION.)

2.  Wear insulating gloves and remove the junction box No.3.

(See JUNCTION BOX No.3 REMOVAL/INSTALLATION.)

Warning

<<High voltage>>

•  For the insulation resistance tester usage, refer to the insulation resistance tester instruction manual. Otherwise, electrocution could result from the voltage generated by the insulation resistance tester.

Caution

<<High voltage>>

•  Use an insulation resistance tester using a testing range of 500 V or less because the voltage applied by the insulation resistance tester may damage the parts.

3.  Wear insulating gloves and insulate the following junction box No.3 terminals using electrical tape.

•  High voltage cable (DC-DC converter cable) terminal

•  High voltage cable (electric compressor cable) side terminal

•  Inverter terminal

4.  Wear insulating gloves and measure the insulation resistance between the following junction box No.3 high voltage cable side terminal 1A and terminal 2A using the insulation resistance tester (500 V range).

•  If the value is not within the standard, wear insulating gloves and replace the junction box No.3.

(See JUNCTION BOX No.3 REMOVAL/INSTALLATION.)

Continuity Inspection

1.  Wear insulating gloves and remove the service plug.

(See SERVICE PLUG REMOVAL/INSTALLATION.)

2.  Wear insulating gloves and remove the junction box No.3.

(See JUNCTION BOX No.3 REMOVAL/INSTALLATION.)

3.  Measure the resistance values between the following junction box No.3 terminals.
