CONFIRMATION DRIVING PATTERN
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off and wait for at least 30 seconds.
-
Start the engine.
-
Turn the Techstream on.
-
Idle the engine for 10 seconds or more.
-
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
-
Read the pending DTCs.
HINT:
-
If a pending DTC is output, the system is malfunctioning.
-
If a pending DTC is not output, perform the following procedure.
-
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
-
Input the DTC: P0367 or P0368.
-
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 is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs.

HINT:
-
If a permanent DTC is output, the system is malfunctioning.
-
If no permanent DTC is output, the system is normal.

CAUTION / NOTICE / HINT
HINT:
-
If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
-
Read Freeze Frame Data using the Techstream. The ECM 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.
