CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.
2. Turn the power 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. Put the engine in inspection mode (maintenance mode). Refer to «INSPECTION MODE PROCEDURE [02/2014 - ]»(ref-644130-S00209877232014072300000)
7. Using the Techstream, switch the ECM from normal mode to check mode. Refer to «CHECK MODE PROCEDURE [02/2014 - ]»(ref-644155-S02505646652014072300000)
8. 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.
9. 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 4.5 minutes or more 1000 4.5 minutes or more 2000 2.5 minutes or more 3000 1.5 minutes or more
10. Check whether misfires have occurred by checking for DTCs and freeze frame data. HINT: Do not turn the power 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.
11. Record the DTC(s), freeze frame data and misfire counts.
12. Turn the power switch off and wait for at least 30 seconds.
13. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

CAUTION / NOTICE / HINT

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. 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.
3. 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.
4. After finishing repairs, check the misfire counts of the cylinders (Cylinder #1 Misfire Count to Cylinder #6 Misfire Count).
5. Be sure to confirm that no misfiring cylinder DTCs are stored again by conducting the confirmation driving pattern after finishing repairs.
6. 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 [02/2014 - ]»(ref-644155-S24908012272014072300000) Put the engine in inspection mode (maintenance mode). Refer to «INSPECTION MODE PROCEDURE [02/2014 - ]»(ref-644130-S00209877232014072300000) 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.
7. 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 +/-20%, the air fuel ratio may be rich (-20% or less) or lean (+20% or higher).
8. 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.
9. An extremely imbalanced drive wheel which causes body vibration may cause misfire DTCs to be stored.
10. 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.

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P106A) Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Read the DTCs. Powertrain > Engine and ECT > Trouble Codes Result Result Proceed to DTC P106A is output A DTC P106A and other DTCs are output B HINT: If any DTCs other than P106A are output, troubleshoot those DTCs first. Result: 2 B GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART [02/2014 - ]»(ref-644155-S10604133742014072300000) Result: 1 A See step 2
2. READ VALUE USING TECHSTREAM (VAPOR PRESSURE PUMP AND MAP) Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Vapor Pressure Pump and MAP. Powertrain > Engine and ECT > Data List Tester Display MAP Vapor Pressure Pump Compare the Vapor Pressure Pump and MAP data from the Data List with day's atmospheric pressure*. Read the Data List twice, when the engine is both cold and warmed up. HINT: *: Standard atmospheric pressure is 101 kPa(abs) [760 mmHg(abs)]. For every 100 m (328 ft) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). The pressure also varies due to the weather (high atmospheric pressure, low atmospheric pressure). Also, check "Atmosphere Pressure" in the Data List. If you do not know the atmospheric pressure refer to the Vapor Pressure Pump value of other vehicles in the workshop and check the difference in pressure. Result Result Proceed to If the Vapor Pressure Pump value differs from the atmospheric pressure by 3.5 kPa [26.254 mmHg] or higher A If the MAP value differs from the atmospheric pressure by 3.5 kPa [26.254 mmHg] or higher B Result: 2 B See step 4 Result: 1 A See step 3
3. REPLACE CANISTER PUMP MODULE Replace the canister pump module. Refer to «REMOVAL [02/2014 - ]»(ref-644279-S12571784502014072300000) Result Proceed to NEXT Result: 1 NEXT See step 5

Note. The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the Techstream. It takes a maximum of approximately 40 minutes. Do not perform the Evaporative System Check when the fuel tank is higher 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).

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG) and turn the Techstream on.
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
