1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON.

3.

Turn the GTS on.

4.

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

5.

Turn the ignition switch off and wait for at least 30 seconds.

6.

Turn the ignition switch to ON [A].

7.

Turn the GTS on.

9.

Start the engine and idle it for 30 seconds or more [B].

10.

Enter the following menus: Powertrain / Engine / Trouble Codes [C].

11.

Read the pending DTCs.

HINT:
·

If a pending DTC is output, the system is malfunctioning.

·

If a pending DTC is not output, perform the following procedure.



12.

Enter the following menus: Powertrain / Engine / Utility / All Readiness.

13.

Input the DTC: P136201.

14.

Check the DTC judgment result.

GTS Display Description
NORMAL
·

DTC judgment completed

·

System normal


ABNORMAL
·

DTC judgment completed

·

System abnormal


INCOMPLETE
·

DTC judgment not completed

·

Perform driving pattern after confirming DTC enabling conditions



HINT:
·

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

·

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

·

If the judgment result is INCOMPLETE, perform steps [D] through [E].

·

[A] to [C]: Normal judgment procedure.

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

·

When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.



15.

With the engine running, drive the vehicle for 5 minutes or more [D].

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.


HINT:

If the engine stops, further depress the accelerator pedal to restart the engine.


16.

Enter the following menus: Powertrain / Engine / Trouble Codes [E].

17.

Read the pending DTCs.

HINT:
·

If a pending DTC is output, the system is malfunctioning.

·

If a pending DTC is not output, perform the following procedure.



18.

Enter the following menus: Powertrain / Engine / Utility / All Readiness.

19.

Input the DTC: P136201.

20.

Check the DTC judgment result.

HINT:
·

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

·

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

·

[A] to [E]: Normal judgment procedure.

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

·

When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.




CAUTION / NOTICE / HINT

NOTICE:
·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.

(Select Powertrain in Health Check and then check the time stamp data.)

·

If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
