(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 / Hybrid Control / Trouble Codes.
(e) Check the DTCs and freeze frame data, and then write them down.
(f) Check the details of the DTCs Hybrid Control System.
2. CHECK FREEZE FRAME DATA AND INFORMATION
(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 set.

(c) Read the information for the information code.
(1) Select the item from among Information 1 to Information 5 that has an information code and click the engine icon to view the additional information.
3. CHECK FOR DTCS (SYSTEMS OTHER THAN HYBRID VEHICLE CONTROL ECU)
HINT
The hybrid vehicle control ECU maintains communication with other computers, including the skid control ECU and power steering ECU. Therefore, if the hybrid vehicle control ECU 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.
4. CLEAR DTCS
NOTICE:
Clearing the DTCs will also clear the freeze frame data, information Information / Freeze Frame Data, and operation history data Operation History Data.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Check that park (P) is selected.
(e) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
(f) Clear DTCs and freeze frame data.
5. CLEAR PERMANENT DTC
HINT
Even if the following procedure is not performed, permanent DTCs are cleared by obtaining a normal judgment during 3 consecutive driving cycles.
(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 / Hybrid Control / Trouble Codes.
(e) Check if permanent DTCs are stored.
HINT
If permanent DTCs are not output, it is not necessary to continue this procedure.
(f) Clear the DTCs.
(g) Perform the respective confirmation driving patterns in order to obtain a normal judgment for the output DTCs.
HINT
* Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs.
* For the confirmation driving pattern, refer to the procedures for the relevant DTC Hybrid Control System.
(h) Perform the universal trip.
HINT
The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle.
(1) Put the engine in inspection mode Component Tests and General Diagnostics.
(2) Idle the engine for 30 seconds or more.
(3) 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.
(4) Allow 10 minutes or more to elapse from the time the engine is started.
(i) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
