STEP 1. Using scan tool (M.U.T.-IIISE), check whether the DTC is set.
STEP 2. Check the generator.
Start the engine with battery charge mode to check whether there is abnormal sound or rotation trouble.(1) Turn on the electric motor switch.
(2) Erase the DTC.
(3) Turn off the electric motor switch.
(4) Set the READY indicator to the on state.
(5) Press the battery charge switch to start the engine with battery charge mode.note | When the main drive lithium-ion battery is fully-charged, the engine does not start. Therefore, carry out under the condition that the battery charge is reduced. If the DTC is set, the engine does not start at all. |
Is the check result normal?
Go to Step 7. : Go to Step 3.
STEP 3. Using scan tool (M.U.T.-IIISE), check whether the DTC is set.
STEP 4. Check the oil level.
STEP 6. Using scan tool (M.U.T.-IIISE), check the actuator test.
STEP 7. Check the high-voltage terminal.
STEP 8. Check the power drive unit [generator control unit (GCU)] connector
Check the power drive unit connector (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line) visually for semi-fitting, damage, moisture/foreign matter intrusion.Is the check result normal?
Go to step 9. : Properly fit the power drive unit connector. Then go to Step 12. : Replace the wiring harness (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line). Then go to Step 12. : replace the wiring harness (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line) and power drive unit (Refer to ). Then go to Step 12 . : Replace the power drive unit (Refer to ). Then go to Step 12.
STEP 9. Check the resistance in the resolver.
STEP 10. Measure resistance between the power drive unit connector and the generator connector (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line)
(1) Remove the wiring harness (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line).
(2) Check the continuity of wring harness (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line).OK: Continuity exists (2 Ω or less)
Is the check result normal?
Replace the generator (Refer to ). Then go to Step 12. Replace the wiring harness (GS1 line, GS2 line, GS3 line, GS4 line, GR1 line and GR2 line). Then go to Step 12.
STEP 11. Test the OBD-II drive cycle.
STEP 12. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 4 . (2) Check the DTC.
Is the DTC set?
Retry the troubleshooting. The inspection is complete.
