1. Power switch ON and wait for 10 seconds or more.
2. Check DTC of the high voltage systems.
Were there any detected DTC related to a high voltage systems other than the traction motor inverter?
YES
>> Check DTC detected item.
NO
>> GO TO 2.
2.
PRECONDITIONING
WARNING:
Disconnect the high voltage. Refer to
GI-33, "How to Disconnect High Voltage"
.
Check voltage in high voltage circuit. (Check that condenser are discharged.)
1. Lift up the vehicle and remove the Li-ion battery under covers. Refer to
2. Disconnect high voltage harness connector and PTC heater harness connector from front side of Li-ion
battery. Refer to
EVB-181, "Removal and Installation"
.
3. Measure voltage between high voltage harness connector terminals and PTC heater harness connector
terminals.
DANGER:
Touching high voltage components without using the appropriate protective equipment will
cause electrocution.
CAUTION:
For voltage measurements, use a tester which can measure to 500 V or higher.
>> GO TO 3.
3.
CHECK TRACTION MOTOR INVERTER HIGH VOLTAGE BUS BAR
Remove bus bar cover from PDM (Power Delivery Module) and check the tightness of high voltage bas bar.
.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Tighten the high voltage bus bar to the specified torque. Refer to
.
4.
CHECK HIGH VOLTAGE HARNESS
Check for an open circuit or short circuit between PDM (Power Delivery Module) and Li-ion battery. Refer to
Is the inspection result normal?
YES
>> Replace the traction motor inverter. Refer to
TMS-103, "Removal and Installation"
.
NO
>> Repair or replace damaged parts.
