-
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.)
-
Warning
-
• Inspections that require installation/removal of the high voltage battery cover cannot be performed because the high voltage battery cannot be disassembled. Perform the operation inspection and troubleshooting on the DTCs output by the PCM, BECM, and heat pump control unit. (See
DTC INSPECTION.)
• The refrigerant piping inspections that require installation/removal of the high voltage battery cover cannot be performed because the high voltage battery cannot be disassembled. Inspect the refrigerant piping and if there is no malfunction with the refrigerant piping, replace the high voltage battery. (See
HIGH VOLTAGE BATTERY REMOVAL/INSTALLATION.)
Operation Inspection
1. Connect the M-MDS to the DLC-2.
2. Select the following menu to perform the forced operation of the climate control system.
-
Note
-
• This function operates at an ambient temperature 5 °C {41 °F}.
- (1) Press [Start] to start the vehicle identification.
-
- (2) Press the [Toolbox] tab.
-
- (3) Press the [Work Support] icon.
-
- (4) Press [EV].
-
- (5) Press [Run] for Compulsory operating Air Conditioner.
-
- (6) Select the Cooling for drive battery.
-
-
• If the test is not completed due to a cause other than the ambient temperature being outside of the implementation conditions, perform the DTC inspection.
DTC Inspection
1. Connect the M-MDS to the DLC-2.
2. Perform the PCM, BECM, and heat pump control unit DTC inspection using the M-MDS, and if an high voltage battery related DTC is output, repair the malfunctioning location according to the applicable DTC troubleshooting.
(See DTC INSPECTION.) (See DTC TABLE [PCM (e-SKYACTIV)].) (See DTC TABLE [BECM (e-SKYACTIV)].) (See DTC TABLE [HEAT PUMP CONTROL UNIT].)
Air Tightness Inspection
1. Perform the air tightness check and leak test for the climate control system refrigerant piping.
(See REFRIGERANT CHARGING.)
-
• If there is a malfunction with the climate control system refrigerant piping, repair or replace the malfunctioning location according to the inspection result.
