NO- INSPECTION END


Diagnosis Procedure


WARNING:
- Because 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.
- Be sure to remove the service plug in order to shut off the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.
- Be sure to put the removed service plug in your pocket and carry it with you so that another person does not accidentally connect it while work is in progress.
- Be sure to wear insulating protective equipment consisting of glove, shoes 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 similar item to prevent other persons from contacting them.
- High Voltage Precautions.

CAUTION:
There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do so in the Service Manual.

1. CHECK SERVICE PLUG INSTALLATION

Check whether service plug is installed normally.
Is the inspection result normal?
YES- GO TO 2.
NO- Repair service plug installation.

2. CHECK SERVICE PLUG SIGNAL-1

1.Turn ignition switch ON.
2.Check the voltage between HPCM harness connector terminals.





Is the inspection result normal?
YES- Perform Intermittent Incident.
NO- GO TO 3.

3. CHECK SERVICE PLUG SIGNAL-2

Check the voltage between HPCM harness connector and ground.





Is the inspection result normal?
YES- GO TO 8.
NO- GO TO 4.

4. PRECONDITIONING


WARNING:
Shut off high voltage circuit. How to Cut Off High Voltage.
Check voltage in high voltage circuit. (Check that condenser are discharged.)
1.Remove trunk finisher front. Trunk Room Trim.





2.Remove harness cover (1).









3.Measure voltage between high voltage harness terminals.









CAUTION:
For voltage measurements, use a tester which can measure to 500 V or higher.
- GO TO 5.

5. CHECK SERVICE PLUG SIGNAL CIRCUIT

1.Turn ignition switch OFF.
2.Disconnect Li-ion battery harness connector.
3.Check the continuity between HPCM harness connector and Li-ion battery harness connector.





4.Also check harness for short to ground and to power.
Is the inspection result normal?
YES- GO TO 6.
NO- Repair or replace error-detected parts.

6. CHECK FUSE

Check that the following fuse is not fusing.





Is the fuse fusing?
YES- Replace the fuse after repairing the applicable circuit.
NO- GO TO 7.

7. CHECK SERVICE PLUG POWER SUPPLY CIRCUIT

1.Check the continuity between Li-ion battery harness connector and fuse and fusible link block No. 3 harness connector.





2.Also check harness for short to ground.
Is the inspection result normal?
YES- Perform the trouble diagnosis for power supply circuit.
NO- Repair or replace error-detected parts.

8. CHECK HPCM GROUND CIRCUIT

Check the continuity between HPCM harness connector and ground.





Is the inspection result normal?
YES- Perform Intermittent Incident.
NO- Repair or replace error-detected parts.
