Diagnosis (Check Mode)
INSPECT DIAGNOSISHINT: hand-held tester only:
Compared to the normal mode, the check mode has more sensitive ability to detect malfunctions. Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the 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
- A/C switched OFF
2. Turn the ignition switch OFF.
3. Prepare a hand-held tester.
4. Connect the hand-held tester to the DLC3 at the lower of the instrument panel.
5. Turn the ignition switch ON and push the hand-held tester ON.
6. Switch the hand-held tester from the normal mode to the check mode (Check that the MIL flashes).
7. Start the engine (MIL goes 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 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, which erases all the DTCs, etc.
10. After checking the DTC, inspect the applicable circuit.
b. Clear the DTC.
1. When using OBD II scan tool or hand-held tester:
When operating an OBD II scan tool (complying with SAE J1978) or hand-held tester to erase the codes, the DTCs and freeze frame data will be erased. (See the OBD II scan tool's instruction book for operating instructions.)
2. When not using OBD II scan tool or hand-held tester:
Remove the EFI fuse from engine room J/B for 10 seconds or more.
