CONFIRMATION DRIVING PATTERN
-
Connect the Techstream to the DLC3.
-
Turn the engine switch on (IG).
-
Turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the Techstream off.
-
Turn the engine switch off.
-
Disconnect the Techstream.
-
Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
-
Connect the cable to the negative (-) battery terminal.
-
Connect the Techstream to the DLC3.
-
Turn the engine switch on (IG).
-
Turn the Techstream on.
-
Wait for 1 second or more. [*1]
HINT:
[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
-
Input the DTC: P061347.
-
Check the DTC judgment result.

|
HINT:
-
If the judgment result shows NORMAL, the system is normal.
-
If the judgment result shows ABNORMAL, the system has a malfunction.
-
If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the Techstream. The TCM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs.
Powertrain > Transmission > Clear DTCs
(e) Turn the engine switch off.
