DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
• Turn power switch OFF and wait at least 90 seconds.
CAUTION:
During this period, never perform vehicle handling such as opening and closing of doors. If some
kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the
vehicle handling.
• Make sure that 12V battery voltage is 11 V or more.
>> GO TO 2.

Diagnosis Procedure
INFOID:0000000010120726
DANGER:
Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of
electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are
handled incorrectly. Be sure to follow the correct work procedures when performing inspection and
maintenance.
WARNING:
• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-
ing inspection or maintenance of high voltage system harnesses and parts.
• To prevent the removed service plug from being connected by mistake during the procedure, always
carry it in your pocket or put it in the tool box.
• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses
before beginning work on the high voltage system.
• Clearly identify the persons responsible for high voltage work and ensure that other persons do not
touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or sim-
ilar item to prevent other persons from contacting them.
• Refer to
EVC-10, "High Voltage Precautions"

PERFORM SELF-DIAGNOSIS OF VCM
With CONSULT
Perform self-diagnosis of VCM.
Is DTC detected other than P3176?
YES
>> Check the DTC. Refer to
NO
>> GO TO 2.

PRECONDITIONING
WARNING:
Disconnect 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 ELECTRIC COMPRESSOR
1. Disconnect electric compressor high voltage harness connector.
2. Check the short circuit between electric compressor terminals.
