4.

Turn the ignition switch off and wait for 2 minutes or more.

5.

Turn the ignition switch to ON and turn the GTS on.

6.

With the vehicle stopped and the shift position in P, turn the ignition switch to ON and wait for at least 70 seconds. [*1]

7.

Turn the ignition switch to ON (READY) and without depressing the accelerator pedal, and while depressing the brake pedal, change the shift position to D and wait for 1 minute. (Step A)[*2]

8.

Drive the vehicle 0.5 m (1.6 ft.) forward and perform step A.[*3]

9.

Drive the vehicle another 0.5 m (1.6 ft.) forward and perform step A. Repeat this procedure 5 times (minimum total driving distance: 2 m (6.6 ft.)).[*4]

HINT:

[*1] to [*4]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.


10.

Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.

CAUTION:
·

Be sure to wear insulated gloves and protective goggles.

·

Disconnect only the connector corresponding to the HV battery cell to be checked. Do not disconnect the other connectors.



NOTICE:

Make sure to use tester probes with a diameter of approximately 0.5 mm (0.0197 in.) when measuring the voltage of each HV battery cell.


a.

Check that the service plug grip is not installed.

NOTICE:

After removing the service plug grip, do not turn the ignition switch to ON (READY), unless instructed by the repair manual because this may cause a malfunction.
