STEP 1. Using scan tool (M.U.T.-IIISE), check whether the DTC is set.
STEP 2. Check the rear motor assembly.
STEP 3. Check the high-voltage terminal.
STEP 4. Check the high-voltage terminal.
STEP 5. Check the REMCU connector
Check the REMCU 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 6. : Properly fit the REMCU 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 REMCU (Refer to ). Then go to Step 9. : Replace the REMCU (Refer to ). Then go to Step 9.
STEP 6. Resolver resistance check
STEP 7. Resistance measurement between the REMCU connector and the rear 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 rear 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 8. Test the OBD-II drive cycle.
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 4 . (2) Check the DTC.
Is the DTC set?
Retry the troubleshooting. The inspection is complete.
