Confirmation Driving Pattern
- Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
- Record the DTC and freeze frame data.
- Set check mode on the intelligent tester (see CHECK MODE PROCEDURE ).
- Read the value on the misfire counter for each cylinder when idling. If the value is displayed on the misfire counter, skip the following confirmation driving procedure.
- Drive the vehicle several times while using the DATA LIST'S MISFIRE RPM and MISFIRE LOAD menu items to keep track of the vehicle's engine speed, load and its surrounding range.
If you have no intelligent tester, turn the ignition switch OFF after the symptom is simulated once. Then repeat the simulation process.
HINT:
In order to force output of the DTC, it is necessary to drive with MISFIRE RPM and MISFIRE LOAD selected in the DATA LIST for the period of time in the chart below. Do not turn the ignition switch OFF. Turning the ignition switch OFF switches the diagnosis system from check mode to normal mode and all DTCs, freeze frame data and other data are erased.
ENGINE RPM SPECIFICATIONEngine RPM Time Idling 3.5 minutes or more 1,000 rpm 3 minutes or more 2,000 rpm 1.5 minutes or more 3,000 rpm 1 minute or more - Check if a misfire occurs by monitoring DTC output and the freeze frame data. Then, record the DTCs, freeze frame data and misfire counter data.
- Turn the ignition switch OFF and wait for at least 5 seconds.
