CAUTION / NOTICE / HINT

Note. Inspect the fuses for circuits related to this system before performing the following procedure.

HINT

1. If the current from the INJ relay is cut because DTC P062D is stored, DTC P1235 will be stored even if the fuel pump for high pressure is normal.
2. 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.

Initial value for (previous average) = 0

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Record the DTC(s) and freeze frame data.
5. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
6. Using the Techstream, switch the ECM from normal mode to check mode. Refer to «CHECK MODE PROCEDURE [04/2013 - ]»(ref-665554-S08558692162014102400000)
7. Read the misfire counts 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.
8. 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
9. Check whether misfires have occurred by checking DTCs and freeze frame data. HINT: Do not turn the engine 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.
10. Record the DTC(s), freeze frame data and misfire counts.
11. Turn the engine switch off and wait for at least 30 seconds.
12. 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

1. If any DTCs other than misfire DTCs are output, troubleshoot those DTCs first.
2. 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.
3. 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.
4. If the misfire still cannot be reproduced even though the conditions stored in the ECM as freeze frame data have been reproduced, one of the following factors is 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.
5. After finishing repairs, check the misfire counts of the cylinders (Cylinder #1 Misfire Count to Cylinder #6 Misfire Count).
6. Be sure to confirm that no misfiring cylinder DTCs are stored again by performing the confirmation driving pattern after finishing repairs.
7. 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 [04/2013 - ]»(ref-665554-S38092923772014102400000) Start the engine and conduct the confirmation driving pattern. Read the misfiring rates 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.
8. 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).
9. 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.
10. An extremely imbalanced drive wheel which causes body vibration may cause misfire DTCs to be stored.

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].
