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 motor generator control ECU during the 1st trip when 2 trip detection logic is used.
Freeze frame data is stored for each of the latest result DTCs, pending DTCs and confirmed DTCs.
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).
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

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 DTC (SYSTEMS EXCEPT MOTOR GENERATOR CONTROL ECU)
Tech Tips
The motor generator control ECU maintains communication with other ECUs, such as the hybrid vehicle control ECU assembly, ECM and skid control ECU assembly. Therefore, if the motor generator control ECU outputs a DTC, it is necessary to check for and make a note of any DTCs stored for other 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 in the CAN communication system malfunctions.
Note
Clearing the DTCs will also clear the freeze frame data.
CLEAR DTC
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Motor Generator / Trouble Codes.
Clear the DTCs and freeze frame data.
