INSPECT DIAGNOSIS (CHECK MODE)

HINT: TOYOTA 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 Normal mode can also be detected in Check mode.

a. Check the DTC.
1. Check the initial conditions.
- Battery positive voltage 11 V or more
- Throttle valve fully closed
- Transaxle in P position
- Air conditioning switched OFF
2. Turn the ignition switch OFF.
3. Prepare a TOYOTA hand-held tester.




4. Connect the TOYOTA hand-held tester to DLC3 at the lower of the instrument panel.
5. Turn the ignition switch ON and switch the TOYOTA hand-held tester ON.




6. Switch the TOYOTA hand-held tester from Normal mode to Check mode (Check that the MIL flashes).
7. Start the engine (MIL goes out after the engine starts).
8. Simulate the conditions of the malfunction described by the customer.

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

9. After simulating the malfunction conditions, use the TOYOTA hand-held tester 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 Check mode to Normal mode, so all DTCs, etc. are erased.

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