- Connect the hand-held tester or the OBD II scan tool to the DLC3.
- Record DTC and the freeze frame data.
- Use the hand-held tester to set to the Check Mode (See «PRE-CHECK»(ref-181812-S42723497822005080500000) ).
- Read the value on the misfire counter for each cylinder when idling. If the value is displayed on the misfire counter, skip the following procedure of confirmation driving.
- 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 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 the DTC of misfire, it is necessary to drive around MISFIRE RPM, MISFIRE LOAD for the following period of time in the data list. Take care not to turn the ignition switch OFF. Turning the ignition switch OFF switches the diagnosis system from check (test) mode to normal mode. So all DTCs, etc., are erased. ENGINE SPEED TIME Engine Speed Time Ignition 3 minutes 30 seconds or more 1,000 rpm 3 minutes or more 2,000 rpm 1 minute 30 seconds or more 3,000 rpm 1 minute or more
- Check whether there is misfire or not by monitoring DTC and the freeze frame data. After that, record them.
- Turn the ignition switch OFF and wait at least 5 seconds.

- Clear DTC's. Disconnecting the battery terminals or EFI No. 1 fuse. Readiness tests will show INCMPL (incomplete).
- Drive the vehicle according to LA#4 drive cycle. Note the state of Readiness Tests. They will change to COMPL as the evaluation monitors operate and if the system passes. This procedure may take approximately 20 minutes or more.
Note. Do not shut off the engine - the results will be invalid.
Pass Condition - No Problem Found by the ECM
If the EVAP evaluation monitor shows COMPL, go to the Non-Continuous Test screen.
Note. Do not shut off the engine - the results will be invalid.

- To get there, go to Advanced OBD II, Onboard Tests, Non-continuous Tests.
- If all of the tests in the time $02 category Tests show Pass, the evaluation monitor has operated and no problem was detected.
Fail Condition - Problem Detected by the ECM
If the EVAP evaluation monitor shows INCMPL, go to the Non-Continuous Test screen.
Scheme 222
Scheme 223
- If all Tests show Pass, the following may have occurred. The EVAP evaluation monitor did not operate. The EVAP evaluation monitor did not finish. The ECM withheld judgement.
- If one or more of the tests in the time $02 category show Fail, the EVAP evaluation monitor did operate and the ECM detected a problem.
- Go to Continuous Tests screen. This is the only place DTC's are listed for the first trip.
Note. The DTC listed may not be valid. A second trip is needed to confirm the DTC.
Scheme 224
Second Trip Procedure
- Vehicle must be cold, ambient temperature approximately between 50°F - 95°F.
- Go to Readiness Tests screen.
- Drive the vehicle according to LA#4 drive cycle. Note the state of EVAP evaluation monitor. This procedure may take approximately 20 minutes or more.
Note. Do not shut off the engine - the results will be invalid.
Scheme 225
If Readiness Tests changes to COMPL, the EVAP evaluation monitor has operated. Check for any stored DTC's.

- If a DTC has stored, the problem has been detected and confirmed by the ECM.
- If no DTC was found, the EVAP monitor operated but no problem was detected.
