DTC CHECK / CLEAR
NOTICE:
When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and Freeze Frame Data recorded in normal mode are cleared. Before changing modes, always check and make a note of DTCs and Freeze Frame Data.
HINT:
To clear permanent DTCs, all of the following conditions must be are met:
Pending DTC | Store condition | Malfunction detected |
Clear condition | System determined to be normal or DTCs cleared using Techstream or Cable disconnected from negative (-) auxiliary battery terminal | |
Confirmed DTC | Store condition | Malfunction detected (2nd trip) |
Clear condition | No malfunctions in 40 driving cycles or DTCs cleared using Techstream or Cable disconnected from negative (-) auxiliary battery terminal | |
Permanent DTC | Store condition | Malfunction detected (2nd trip) |
Clear condition | Power switch turned to on (IG) after normal judgment obtained in 3 consecutive driving cycles or After DTCs cleared using Techstream or cable disconnected from negative (-) auxiliary battery terminal, universal trip performed and normal judgment obtained for 2 trips (not for misfire and fuel system DTCs) or After DTCs cleared using Techstream or cable disconnected from negative (-) auxiliary battery terminal, malfunction not detected when universal trip driving performed (misfire and fuel system DTCs) | |
MIL | ON | Malfunction detected (2nd trip) |
OFF | Power switch turned to on (IG) after normal judgment obtained in 3 consecutive driving cycles or DTCs cleared using Techstream or Cable disconnected from negative (-) auxiliary battery terminal |
HINT:
CHECK 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 / Engine / Trouble Codes.
Powertrain > Engine > Trouble Codes(e) Check the DTC(s) and Freeze Frame Data, and then write them down.
Techstream 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.) |
(f) Check the details of the DTC(s).

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) Turn the Techstream on.
(d) Enter the following menus: Health Check.
(e) Perform the following steps when the data setting screen is displayed.
(f) Select the systems for which to perform Health Check and check for time stamp data.
(g) 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.
(h) After Health Check has completed, select "Time Stamp Data" to display the Time Stamp screen.
(i) Select the desired system from the drop-down list on the bottom of the Time Stamp screen.
(j) Check the order and time which DTCs were stored for the selected system.
CLEAR DTC (Pending and Confirmed 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 / Engine / Trouble Codes.
(e) Clear the DTCs.
Powertrain > Engine > Clear DTCsCLEAR DTC (Pending and Confirmed DTC without using Techstream)
(a) Perform either of the following operations:
NOTICE:
After turning power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

(1) Disconnect the cable from the negative (-) auxiliary battery terminal for more than 1 minute.
(2) Remove the EFI-MAIN NO. 4 fuse from the No. 1 engine room relay block and No. 1 junction block assembly located inside the engine compartment for more than 1 minute.
CLEAR 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 / Engine / Trouble Codes.
Powertrain > Engine > Trouble CodesHINT:
If "PERMANENT" in the top right of the screen displays "YES", 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.
Powertrain > Engine > 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.
HINT:
The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle.
CAUTION:
When performing a driving pattern, obey all speed limits and traffic laws.
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.
(i) Turn the power switch off and wait for 2 minutes or more.
(j) Turn the power switch on (IG).
(k) Enter the following menus: Powertrain / Engine / Trouble Codes.
Powertrain > Engine > Trouble Codes(l) Check that the permanent DTCs have been cleared.
HINT:
If permanent DTCs are not output, it is not necessary to continue this procedure.
(m) Perform the normal judgment procedure in the respective confirmation driving pattern of each output DTC.
HINT:
(n) With the power switch on (READY) wait for 5 seconds or more. (Except when the power switch is already turned on (READY) or the engine is running)
(o) Turn the power switch off and wait for 2 minutes or more.
(p) Turn the power switch on (IG).
(q) Enter the following menus: Powertrain / Engine / Trouble Codes.
