·

When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>HYBRID BATTERY SYSTEM>DTC CHECK / CLEAR



1.

Connect the GTS to the DLC3.

2.

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

3.

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

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.

Drive the vehicle on urban roads for approximately 10 minutes.[*1]

HINT:

[*1]: Normal judgment procedure.

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


7.

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

8.

Check the DTC judgment result.

HINT:
·

If the judgment result shows NORMAL, the system is normal.

·

If the judgment result shows ABNORMAL, the system has a malfunction.

·

If the judgment result shows INCOMPLETE, perform the normal judgment procedure again.

NOTICE:
·

Make sure to check the polarity of each terminal (positive (+) or negative (-)) before connecting a tester.

·

Read the resistance after the value has stabilized.

·

In order to avoid damaging the terminals of the battery ECU assembly, make sure to use tester probes with a diameter of approximately 0.5 mm (0.0197 in.) when measuring the resistance of the battery ECU assembly.
