Motor Rotor Position Sensor Circuit Inspection (Traction Motor Control Module)
NOTE: Before testing, check for DTCs. If any DTCs are indicated, troubleshoot the indicated DTCs first.
Determine possible failure area (short in traction motor rotor position sensor circuit, others)
Turn the vehicle to the OFF (LOCK) mode.
-2. Do the 12 volt battery terminal disconnection procedure .
-3. Disconnect the following connector.
| PCU 33P connector |
Check for continuity between the following test points and body ground individually.
| Test condition | Vehicle OFF (LOCK) mode |
| PCU 33P connector: disconnected |
| Connector | Test circuit | Terminal |
| PCU 33P connector | S1M | No. 9 |
| S2M | No. 30 | |
| S3M | No. 20 | |
| S4M | No. 31 | |
| R1M | No. 8 | |
| R2M | No. 19 |
- If there is no continuity, the traction motor rotor position sensor circuit is ok. If there is no continuity, do the step 2.
-5. Disconnect the following connector.
| Motor rotor position sensor 12P connector |
Check for continuity between the following test points and body ground individually.
| Test condition | Vehicle OFF (LOCK) mode |
| Motor rotor position sensor 12P connector: disconnected | |
| PCU 33P connector: disconnected |
| Connector | Test circuit | Terminal |
| PCU 33P connector | S1M | No. 9 |
| S2M | No. 30 | |
| S3M | No. 20 | |
| S4M | No. 31 | |
| R1M | No. 8 | |
| R2M | No. 19 |
- If there is no continuity, faulty the transmission (e-CVT) assembly. If there is continuity, repair a short in the traction motor rotor position sensor circuit between the PCU and the traction motor rotor position sensor.
Open wire check (traction motor rotor position sensor circuit) :
Check for continuity between the following terminals respectively.
| Test condition | Vehicle OFF (LOCK) mode |
| PCU 33P connector: disconnected | |
| Motor rotor position sensor 12P connector: disconnected |
