Scheme 386
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and 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.
- Turn the ignition switch to ON and turn the Techstream on [A].
- Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher with all the accessories switched off [B].
- With the engine warmed up, idle the engine for 2 minutes or more [C].
- Drive the vehicle at a speed between 60 and 135 km/h (37 and 84 mph) for 5 minutes or more [D]. WARNING: When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- Enter the following menus: Powertrain / Engine / Trouble Codes [E].
- Read the pending DTCs. HINT: If a pending DTC is output, the system is malfunctioning.
- If no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR [12/2013 - ]»(ref-636036-S39197130512014070700000) HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
CAUTION / NOTICE / HINT
Note. Inspect the fuses for circuits related to this system before performing the following procedure.
HINT
- Bank 1 refers to the bank that includes the No. 1 cylinder*. *: The No. 1 cylinder is the cylinder which is farthest from the transaxle.
- Bank 2 refers to the bank that does not include the No. 1 cylinder.
- Sensor 1 refers to the sensor closest to the engine assembly.
- Sensor 2 refers to the sensor farthest away from the engine assembly.
- 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.
- A low air fuel ratio sensor voltage could be caused by a rich air fuel mixture. Check for conditions that would cause the engine to run rich.
- A high air fuel ratio sensor voltage could be caused by a lean air fuel mixture. Check for conditions that would cause the engine to run lean.

CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Record the DTC(s) and freeze frame data.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Switch the ECM from normal mode to check mode. Refer to «CHECK MODE PROCEDURE [12/2013 - ]»(ref-636036-S31627726552014070700000)
- Read the misfire count of each cylinder (Cylinder #1 Misfire Count to Cylinder #6 Misfire Count) with the engine idling. If any misfire count is displayed, skip the following confirmation driving pattern.
- Drive the vehicle so that the vehicle conditions displayed in Misfire RPM and Misfire Load of the Data List are the same as the freeze frame data. Perform this step several times. HINT: In order to store misfire DTCs, it is necessary to operate the vehicle for the period of time shown in the table below, confirm the Misfire RPM and Misfire Load in the Data List. Engine speed Duration Idling 8.0 minutes or more 1000 4.5 minutes or more 2000 2.5 minutes or more 3000 1.5 minutes or more
- Check whether misfires have occurred by checking for DTCs and freeze frame data. HINT: Do not turn the ignition switch off until the output DTC(s) and freeze frame data have been recorded. When the ECM returns to normal mode (default), the stored DTC(s), freeze frame data and other data are cleared.
- Record the DTC(s), freeze frame data and misfire counts.
- Turn the ignition switch off and wait for at least 30 seconds.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Note. Inspect the fuses for circuits related to this system before performing the following procedure.
HINT
- If any DTCs other than misfire DTCs are output, troubleshoot those DTCs first.
- If the misfire does not recur when the vehicle is brought to the workshop, reproduce the conditions stored in the ECM as freeze frame data.
- If the misfire still cannot be reproduced even though the conditions stored in the ECM as freeze frame data have been reproduced, the following factors can be considered to be a possible cause of the problem: There was insufficient fuel in the tank. Improper fuel was used. The spark plugs have been contaminated. The problem requires further diagnosis.
- After finishing repairs, check the misfire counts of the cylinders (Cylinder #1 Misfire Count to Cylinder #6 Misfire Count).
- Be sure to confirm that no misfiring cylinder DTCs are stored again by conducting the confirmation driving pattern after finishing repairs.
- For 6 cylinder engine, the ECM intentionally does not set the specific misfiring cylinder DTCs at high engine speed. If misfires occur only in high engine speed areas, only DTC P0300 is set. In the event of DTC P0300 being present, perform the following operations: Clear the DTCs. Refer to «DTC CHECK / CLEAR [12/2013 - ]»(ref-636036-S39197130512014070700000) Start the engine and conduct the confirmation driving pattern. Read the misfiring counts of each cylinder or DTC(s) using the Techstream. Repair the cylinder(s) that has a high misfiring rate or is indicated by the DTC. After finishing repairs, conduct the confirmation driving pattern again, in order to verify that DTC P0300 is not set.
- When one of Short FT #1, Long FT #1, Short FT #2 or Long FT #2 in the freeze frame data is outside the range of +/-15%, the air fuel ratio may be rich (-15% or less) or lean (+15% or higher).
- When Coolant Temp in the freeze frame data is less than 75°C (167°F), the misfires have occurred only while warming up the engine.
- An extremely imbalanced drive wheel which causes body vibration may cause misfire DTCs to be stored.
- 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.
- CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO MISFIRE DTCS) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Trouble Codes. Read the DTCs.

Result: 2 B GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART [12/2013 - ]»(ref-636036-S07011333302014070700000) Result: 1 A See step 2

Powertrain > Engine > Data List Tester Display Cylinder #1 Misfire Count Cylinder #2 Misfire Count Cylinder #3 Misfire Count Cylinder #4 Misfire Count Cylinder #5 Misfire Count Cylinder #6 Misfire Count Start the engine and allow the engine to idle. Read each value for Cylinder #1 Misfire Count to Cylinder #6 Misfire Count displayed on the Techstream. If no misfire counts occur in any cylinders, perform procedure [A] and [B] and then check the misfire counts again. Drive the vehicle with the Misfire RPM and Misfire Load noted in the "Read Value Using Techstream (Misfire RPM And Misfire Load)" procedures above [A]. Read the Cylinder #1 Misfire Count to Cylinder #6 Misfire Count or DTCs displayed on the Techstream [B]. Result Result Proceed to Most misfires occur in only 1 or 2 cylinders A 3 cylinders or more have equal misfire counts B HINT: If it is difficult to reproduce misfires for each cylinder, check the Data List item called Misfire Margin. Try to find vehicle driving conditions that lower the Misfire Margin value. Values above 30% are considered normal. If the freeze frame data record of the engine coolant temperature is less than 75°C (167°F), the misfire may be detected only when the engine is cold. If the freeze frame data record of the Engine Run Time is below 120 seconds, the misfire may be detected immediately after the engine is started. Result: 2 B See step 17 Result: 1 A See step 7

Note. The Evaporative System Check (Automatic Mode) consists of 6 steps performed automatically by the Techstream. It takes a maximum of approximately 24 minutes. Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable. Do not run the engine during this operation. When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).
