1. Dtc check (normal mode)
Notice
: hand–held tester only: when the diagnostic system is switched from the normal mode to the check mode, all the dtcs and freeze frame data recorded in the normal mode will be erased. So before switching modes, always check the dtcs and freeze frame data, and note them down.

- Turn the ignition switch off.
- Connect the obd ii scan tool or hand–held tester to dlc3.

Notice
: when simulating symptoms with an obd ii scan tool (excluding hand–held tester) to check the dtcs, use the normal mode. For codes on the dtcs chart subject to ”2 trip detection logic”, turn the ignition switch off after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the mil is indicated on the instrument panel and dtcs are recorded in the ecm.
