STEP 1. Using scan tool (M.U.T.-IIISE), check whether the DTC is set.
STEP 2. Check the front motor assembly.
STEP 3. Using scan tool (M.U.T.-IIISE), check whether the other 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 (FEMCU) connector
Check the power drive unit connector (S1 line, S2 line, S3 line, S4 line, R1 line and R2 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 (S1 line, S2 line, S3 line, S4 line, R1 line and R2 line). Then go to Step 12. : Replace the wiring harness (S1 line, S2 line, S3 line, S4 line, R1 line and R2 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. Resistance measurement between the power drive unit connector and the front motor assembly connector (S1 line, S2 line, S3 line, S4 line, R1 line and R2 line)
(1) Remove the wiring harness (S1 line, S2 line, S3 line, S4 line, R1 line and R2 line).
(2) Check the continuity of wring harness (S1 line, S2 line, S3 line, S4 line, R1 line and R2 line).OK: Continuity exists (2 Ω or less)
Is the check result normal?
Replace the front motor assembly (Refer to ). Then go to Step 12. Replace the wiring harness (S1 line, S2 line, S3 line, S4 line, R1 line and R2 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.
