DTC CHECK / CLEAR
CHECK FOR DTCS
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / HV battery / Trouble Codes.
Powertrain > HV Battery > Trouble Codes(e) Check the DTCs and freeze frame data, and then write them down.
(f) Check the details of the DTCs.
Display Item | 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.) |
(1) Enter the following menus: Powertrain / HV Battery / Utility / Check Mode.

(2) Check items on the display and press "Next".
NOTICE:
CHECK FREEZE FRAME DATA
(a) If a DTC is present, select it in order to display its freeze frame data.
(b) Read the freeze frame data recorded when the DTC was stored.
CHECK TIME STAMP
HINT:
By checking Time Stamp, the time and order in which DTCs were stored in an ECU can be checked.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Health Check.
(d) Perform the following steps when the data setting screen is displayed.
(e) Select the systems for which to perform Health Check and check for time stamp data.
(f) Select "Yes" when "Do you want to store time stamp data?" is displayed.
HINT:
If "Yes" is not selected, time stamp data will not be stored.
(g) After Health Check has completed, select "Time Stamp Data" to display the Time Stamp screen.
(h) Select the desired system from the drop-down list on the bottom of the Time Stamp screen.
(i) Check the order and time which DTCs were stored for the selected system.
CHECK FOR DTCS (SYSTEMS EXCEPT BATTERY ECU ASSEMBLY)
HINT:
The battery ECU assembly maintains communication with other computers, including the motor generator control ECU, the ECM, and hybrid vehicle control ECU. Therefore, if the battery ECU assembly outputs a warning, it is necessary to check and record the DTCs of all systems.
(a) If DTCs are present, check the relevant systems.
HINT:
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
NOTICE:
Clearing the DTCs will also clear the freeze frame data.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / HV battery / Trouble Codes.
Powertrain > HV Battery > Trouble Codes(e) Clear DTCs and freeze frame data.
Powertrain > HV Battery > Clear DTCsCLEAR PERMANENT DTC
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / HV Battery / Trouble Codes.
Powertrain > HV Battery > Trouble CodesHINT:
If "YES" is displayed for the value of "PERMANENT" at the top right of the Techstream screen, permanent DTCs are stored.
(e) Select the "Generic" tab.
(f) Check if permanent DTCs are stored.
HINT:
If permanent DTCs are not output, it is not necessary to continue this procedure.
(g) Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Powertrain > HV Battery > Clear DTCsNOTICE:
Do not clear the DTCs or disconnect the cable from the auxiliary battery terminal after performing this step.
(h) Perform the universal trip.
CAUTION:
When performing the driving pattern, obey all speed limits and traffic laws.
HINT:
The universal trip driving pattern and normal judgment procedure can be performed consecutively in the same driving cycle.
(1) Turn the power switch on (READY) and wait for 30 seconds or more.
(2) Drive the vehicle at 40 km/h (25 mph) or more for a total of 5 minutes or more.
HINT:
It is possible to complete the drive pattern even if the vehicle decelerates to less than 40 km/h (25 mph) during the driving cycle provided that the vehicle is driven at 40 km/h (25 mph) or more for a total of 5 minutes.
(3) Allow 10 minutes or more to elapse from the time the power switch turned on (READY).
(i) Turn the power switch off and wait for 2 minutes or more.
(j) Perform the normal judgment procedure in the respective confirmation driving pattern of each output DTC.
HINT:
Do not turn the power switch off by mistake during this step.
(k) With power switch on (READY) and wait for 5 seconds or more.
(l) Turn the power switch off and wait for 2 minutes or more.
(m) Turn the power switch on (IG).
(n) Enter the following menus: Powertrain / HV Battery / Trouble Codes.
Powertrain > HV Battery > Trouble Codes(o) Check that the permanent DTCs have been cleared.
HINT:
If permanent DTCs are not output, it is not necessary to continue this procedure.
(p) Perform the normal judgment procedure in the respective confirmation driving pattern of each output DTC.
HINT:
Do not turn the power switch off by mistake during this step.
(q) With power switch on (READY) and wait for 5 seconds or more.
(r) Turn the power switch off and wait for 2 minutes or more.
(s) Turn the power switch on (IG).
(t) Enter the following menus: Powertrain / Motor Generator / Trouble Codes.
Powertrain > HV Battery > Trouble Codes(u) Check that the permanent DTCs have been cleared.
HINT:
Permanent DTCs will be cleared if a normal judgment is obtained during 3 consecutive driving cycles with the MIL illuminated.
