With Generic Scan Tool

INSPECT DIAGNOSIS (NORMAL MODE)

HINT: DTCs can be displayed on the OBD II scan tools. The hand- held tester displays the current DTCs and pending DTCs. Some DTCs are set when the same malfunction is detected in consecutive driving cycle. The pending DTCs are set when the malfunction is detected once.




a. Check the MIL.
1. The MIL comes on when the ignition switch is turned ON and the engine is not running.

HINT: If the MIL does not light up, troubleshoot the combination meter.

2. When the engine is started, the MIL should go off.
If the lamp remains on, the diagnosis system has detected a malfunction or abnormality in the system.

b. Check the DTC.

1. Prepare an OBD II scan tool (complying with SAE J1978) or hand-held tester.




2. Connect the OBD II scan tool or hand-held tester to DLC3 at the lower of the instrument panel.
3. Turn the ignition switch ON and turn the OBD II scan tool or hand-held tester switch ON.
4. Use the OBD II scan tool or hand-held tester to check the DTCs and freeze frame data and note them down (For operating instructions, see the OBD II scan tool's instruction book).
5. See Trouble Code Descriptions to confirm the details of the DTCs.

NOTE: When simulating symptoms with an OBD II scan tool (excluding hand-held tester) to check the DTCs, use normal mode. For codes on the DTCs chart subject to "2-trip detection logic", turn the ignition switch off after the symptoms have been simulated the 1st time. Then repeat the simulation process again. When the problem has been simulated twice, the MIL comes on on the instrument panel and the DTCs are recorded in the ECM.

c. When using the OBD II scan tool or hand-held tester:
Clearing the DTCs.
1. Connect the OBD II scan tool or hand-held tester to the DLC3.
2. Turn the ignition switch to the ON position and push the OBD II scan tool or the hand-held tester main switch on.
3. When you use hand-held tester:
Select the item "DIAGNOSIS / ENHANCED OBD / DTC INFO / CLEAR CODES [YES] button".

HINT: When operating the 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.)
