CONFIRMATION DRIVING PATTERN

HINT:

After repair has been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>PA10 HYBRID CONTROL SYSTEM (for LITHIUM-ION BATTERY)>UTILITY


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.

Turn the ignition switch to ON (READY).

7.

Drive the vehicle at approximately 30 km/h (19 mph) or more for approximately 5 seconds or more using the engine.

8.

Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

9.

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 driving pattern again.




CAUTION / NOTICE / HINT

HINT:
·

A seized engine, mechanical malfunction of the hybrid vehicle transaxle can be suspected.

·

If this DTC is output, the engine or gears in the transaxle may have seized or foreign matter have been caught in either of them. Therefore, check the engine oil, hybrid transaxle fluid, coolant (for Engine) and coolant (for Inverter) levels.
