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 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 hand-held tester




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




6. Switch the hand-held tester from normal mode to check mode (check that the MIL flashes).
7. Start the engine (MIL turns off 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 hand-held tester diagnosis selector to check for DTCs and freeze frame data, etc.

HINT: Take care not to turn the ignition switch OFF. If the ignition switch is turned off, the diagnosis system is switched from check mode to normal mode, which erases all DTCs, etc.

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

b. Clear the DTC.
Operating the OBD II scan tool (complying with SAE J1978) or hand-held tester can erase the DTC and freeze frame data. (see the OBD II scan tool's instruction book for operating instructions).
