- 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. Check for DTCs with the HDS.

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. EPS control unit check (update):
1. Update the EPS control unit if it does not have the latest software.
2. Turn the vehicle to the OFF (LOCK) mode, then start the engine.
3. Check for DTCs with the HDS.
