STEP 1. 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 2. : Properly fit the power drive unit connector. Then go to Step 9. : Replace the wiring harness (S1 line, S2 line, S3 line, S4 line, R1 line and R2 line). Then go to Step 9. : 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 9 . : Replace the power drive unit (Refer to ). Then go to Step 9.
STEP 2. Check the front motor assembly.
STEP 3. Check the resistance in the resolver.
STEP 4. 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 9. Replace the wiring harness (S1 line, S2 line, S3 line, S4 line, R1 line and R2 line). Then go to Step 9.
STEP 5. Using scan tool (M.U.T.-IIISE), check whether the other DTC is set.
STEP 6. Check the oil level.
STEP 8. Using scan tool (M.U.T.-IIISE), check the actuator test.
STEP 9. 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 1 . (2) Check the DTC.
Is the DTC set?
Retry the troubleshooting. The inspection is complete.
