CHECK FOR DTCS
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
Check the DTCs and freeze frame data, and then write them down.
Check the details of the DTCs.
Tech Tips
GTS Display | Description |
---|---|
Test Failed | Shows the malfunction judgment results during the current trip. |
Pending | Shows the malfunction judgment results up to now (Indicates the possibility of a malfunction when no DTC is confirmed.) |
Confirmed | Shows the DTCs confirmed up to now (The number of current trips differs for each DTC.) |
A pending DTC is a DTC that is stored in the hybrid vehicle control ECU assembly during the 1st trip when the 2 trip detection logic is used.
Freeze frame data is stored for each of the latest result DTCs, pending DTCs and confirmed DTCs.
Enter the following menus: Powertrain / Hybrid Control / Utility / Check Mode.

Check items on the display and press "Next".
Note
All the stored DTCs and freeze frame data are cleared if the hybrid vehicle control ECU assembly is changed from normal mode to check mode. Before changing modes, always check and note any DTCs and freeze frame data.
Changing from normal mode to check mode function is not available when the power switch is turned on (READY).
If a DTC is stored, check and note the DTC and freeze frame data following the GTS display, then change from normal mode to check mode.
CHECK FREEZE FRAME DATA
If a DTC is present, select it in order to display its freeze frame data.
Read the freeze frame data recorded when the DTC was stored.
CHECK TIME STAMP
Tech Tips
By checking Time Stamp, the time and order in which DTCs were stored in an ECU can be checked.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Health Check.
Perform the following steps when the data setting screen is displayed.
Select the systems for which to perform Health Check and check for time stamp data.
Selectable items:
Powertrain
Chassis
Body
Store All Data
Select "Yes" when "Do you want to store time stamp data?" is displayed.
Tech Tips
If "Yes" is not selected, time stamp data will not be stored.
After Health Check has completed, select "Time Stamp Data" to display the Time Stamp screen.
Select the desired system from the drop-down list on the bottom of the Time Stamp screen.
Check the order and time which DTCs were stored for the selected system.
CHECK FOR DTCS (CAN BUS CHECK)
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: System Select / CAN Bus Check.
Check for communication malfunction DTCs.
Tech Tips
If DTCs related to a CAN communication are output, first troubleshoot and repair the CAN communication system.
CHECK FOR DTCS (SYSTEMS EXCEPT HYBRID VEHICLE CONTROL ECU ASSEMBLY)
Tech Tips
The hybrid vehicle control ECU assembly maintains communication with other computers, including the motor generator control ECU, the ECM, skid control ECU assembly and power steering ECU assembly. Therefore, if the hybrid vehicle control ECU assembly outputs a warning, it is necessary to check and record the DTCs of all systems.
If DTCs are present, check the relevant systems.
Tech Tips
If DTCs for the CAN communication system are present in addition to other DTCs, first troubleshoot and repair any malfunctions in the CAN communication system.
CLEAR DTCS
Note
Clearing the DTCs will also clear the freeze frame data.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
Clear DTCs and freeze frame data.
