CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.

2. Turn the power switch on (IG) and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4. Turn the power switch off.

5. Turn the power switch on (READY) and turn the Techstream on.

6. With the shift lever in D, depress both the accelerator pedal and brake pedal at the same time to raise the SOC to a sufficient level.

7. Move the shift lever to P, check that the engine is stopped and move the shift lever to N.

8. Set the A/C for maximum cooling.

9. Leave the vehicle for a few minutes.

10. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

11. Check that permanent DTCs are cleared.

12. If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (HV)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

(d) Check if DTCs are output.

Result:









HINT
- *1: If any INF codes are output for this DTC, refer to the corresponding diagnostic procedure.
- P0A94-585 may be output due to a malfunction which causes the DTCs in the table above to be output. In this case, first troubleshoot the output DTCs in the table above. Then, perform a reproduction test to check that no DTCs are output.

(e) Turn the power switch off.
