Diagnosis (Check Mode)

INSPECT DIAGNOSIS (CHECK MODE)

HINT: Hand-held tester only: Compared to the normal mode, the check mode has high sensing ability to detect malfunctions. Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the check mode.

2. Connect the scan tool (OBD II scan tool or hand-held tester) to the DLC3.
3. Turn the ignition switch ON.
4. Turn the scan tool switch ON.




5. Switch the hand-held tester from the normal mode to the check mode (the MIL flashes).
6. Start the engine (the MIL goes out after the engine starts).
7. Simulate the conditions of the malfunction described by the customer.

NOTE: Leave the ignition switch ON until you have checked the DTCs, etc.

8. After simulating the malfunction conditions, use the scan tool diagnosis selector to check the DTCs and freeze frame data, etc.

HINT: Take care not to turn the ignition switch OFF, as turning it off switches the diagnosis system from the check mode to the normal mode, so all the DTCs, etc. are erased.

9. After checking the DTC, inspect the applicable circuit.

b. Clear the DTC.
The following operation will erase the DTC and freeze frame data. Operating the scan tool (OBD II scan tool or hand-held tester) to erase the codes (See the scan tool instruction book).
