| 52-06 Torque Sensor Offset Out of Range |
- 1. Problem verification:
1. Turn the vehicle to the ON mode.
2. Clear the DTC with the HDS.
3. Turn the vehicle to the OFF (LOCK) mode, then start the engine.
4. Turn the steering wheel from lock to lock at least 5 times.
5. Check for DTCs with the HDS.
DTC Description DTC Freeze Frame 52-06 Torque Sensor Offset Out of Range Is DTC 52-06 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the Freeze data/on-board snapshot.
- 2. Shorted wire check (VS2, TRQ SUB lines to power) 1:
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the following connector.
EPS control unit connector B (16P) 3. Turn the vehicle to the ON mode.
4. Measure the voltage between test points 1 and 2 individually.
Test condition Vehicle ON mode EPS control unit connector B (16P): disconnected Test point 1 EPS control unit connector B (16P) No. 13 Test point 2 Body ground Test point 1 EPS control unit connector B (16P) No. 15 Test point 2 Body ground Is there battery voltage?
YES
Repair a short to power in the wire between the EPS control unit and the torque sensor.
NO
The VS2 and TRQ SUB wires are not shorted to power. Go to step 3.
- 3. Shorted wire check (VS2, TRQ SUB lines) 2:
1. Turn the vehicle to the OFF (LOCK) mode.
2. Check for continuity between test points 1 and 2 individually.
Test condition Vehicle OFF (LOCK) mode EPS control unit connector B (16P): disconnected Test point 1 EPS control unit connector B (16P) No. 13 Test point 2 Body ground Test point 1 EPS control unit connector B (16P) No. 15 Test point 2 Body ground Is there continuity?
YES
Go to step 4.
NO
The VS2 and TRQ SUB wires are not shorted. Go to step 5.
- 4. Shorted wire check (VS2, TRQ SUB lines) 3:
1. Disconnect the following connector.
Torque sensor 6P connector 2. Check for continuity between test points 1 and 2 individually.
Test condition Vehicle OFF (LOCK) mode Torque sensor 6P connector: disconnected EPS control unit connector B (16P): disconnected Test point 1 EPS control unit connector B (16P) No. 13 Test point 2 Body ground Test point 1 EPS control unit connector B (16P) No. 15 Test point 2 Body ground Is there continuity?
YES
Repair a short to body ground in the wire between the EPS control unit and the torque sensor.
NO
- 5. Open wire check (VS2, TRQ SUB lines):
1. Disconnect the following connector.
Torque sensor 6P connector 2. Check for continuity between test points 1 and 2 individually.
Test condition Vehicle OFF (LOCK) mode Torque sensor 6P connector: disconnected EPS control unit connector B (16P): disconnected Test point 1 EPS control unit connector B (16P) No. 13 Test point 2 Torque sensor 6P connector No. 3 Test point 1 EPS control unit connector B (16P) No. 15 Test point 2 Torque sensor 6P connector No. 6 Is there continuity?
YES
The VS2 and TRQ SUB wires are OK. Go to step 6.
NO
Repair an open in the wire between the EPS control unit and the torque sensor.
- 6. EPS control unit check (update):
1. Reconnect the following connectors.
EPS control unit connector B (16P) Torque sensor 6P connector 2. Update the EPS control unit if it does not have the latest software.
3. Clear the DTC with the HDS.
4. Turn the vehicle to the OFF (LOCK) mode, then start the engine.
5. Turn the steering wheel from lock to lock at least 5 times.
6. Check for DTCs with the HDS.
DTC Description DTC Freeze Frame 52-06 Torque Sensor Offset Out of Range Is DTC 52-06 indicated?
YES
Go to step 7.
NO
Troubleshooting is complete.
- 7. EPS control unit check (substitution):
1. Turn the vehicle to the OFF (LOCK) mode.
2. Substitute a known-good EPS control unit .
3. Clear the DTC with the HDS.
4. Turn the vehicle to the OFF (LOCK) mode, then start the engine.
5. Turn the steering wheel from lock to lock at least 5 times.
6. Check for DTCs with the HDS.
