HINT:
When the 2 or more codes for a misfiring cylinder are recorded repeatedly but no Random Misfire code is
recorded, it indicates that the misfires were detected and recorded at different times.
WIRING DIAGRAM
CONFIRMATION DRIVING PATTERN
(1) Connect the TOYOTA hand±held tester or OBD II scan tool.
(2) Record DTC and the freeze frame data.
(3) Use the TOYOTA hand±held tester to set to Check Mode. (See page DI±197)
(4) Drive the vehicle several times with the engine speed, load and its surrounding range shown with
ENGINE SPD, CALC LOAD in the freeze frame data or MISFIRE RPM, MISFIRE LOAD in the data list.
If you have no TOYOTA hand±held tester, turn the ignition switch OFF after the symptom is simulated
the first time. Then repeat the simulation process again.
HINT:
In order to memorize DTC of misfire, it is necessary to drive around MISFIRE RPM, MISFIRE LOAD in the
data list for the following period of time.
Engine SpeedTime
Idling3 minutes 30 seconds or more
1000 rpm3 minutes or more
2000 rpm1 minute 30 seconds or more
3000 rpm1 minute or more
(5) Check whether there is misfire or not by monitoring DTC and the freeze frame data. After that, record
them.
(6) Turn ignition switch OFF and wait at least 5 seconds.

1. Confirm if vehicle is currently misfiring, running rough or hesitating.
If YES ± Go to Step 2.
If NO ± Review Freeze Frame Data and attempt to operate vehicle under similar
driving conditions ± see notes below for information that makes it more likely to
duplicate misfire.
NOTE:
The following activities will turn off misfire detection:
Changing engine RPM greater than 150 RPM.
Changing throttle position quickly.
Misfire duplication can be duplicated most readily when the engine speed and throttle
angle are held nearly constant for at least 2 minutes.
