CHECK FREEZE FRAME DATA
Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.
Note
Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Check the freeze frame data by following the prompts on the intelligent tester display.
Tech Tips
The engine conditions (ECU data) when DTCs were stored can be checked (chronological freeze frame data).
Compare the reported malfunction symptoms against the DTC list.
After performing repairs, perform a confirmation test based on the driving conditions confirmed above.
