CHECK DTC
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the intelligent tester ON.
Select the following menu items: Powertrain / Engine and ECT / DTC.
Check DTCs and freeze frame data, and then write them down.
Tech Tips
If you need help when using the intelligent tester, refer to the instruction manual.
Confirm the details, referring the DTC chart.

FREEZE FRAME DATA
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the intelligent tester ON.
Read DTCs by selecting the following menu items: Powertrain / Engine and ECT / DTC.
Select a parameter(s) to check the freeze frame data.
Note down the DTC(s) and freeze frame data.
Tech Tips
If you need help when using the intelligent tester, refer to the instruction manual.
CLEAR DTC AND FREEZE FRAME DATA (using the intelligent tester)
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON (do not start the engine) and turn the intelligent tester ON.
Select the following menu items: Powertrain / Engine and ECT / DTC / Clear.
Erase DTCs and freeze frame data by pressing the YES button on the tester.
Tech Tips
If you need help when using the intelligent tester, refer to the instruction manual.
CLEAR DTC AND FREEZE FRAME DATA (not using the intelligent tester)
Remove the EFI fuse from the engine room R/B for more than 60 seconds, or disconnect the negative battery cable for more than 60 seconds. When disconnecting the negative battery cable, perform the "INITIALIZE" procedure.
