    *** Any OBDII scanner can be used to clear DTC. Autozone will do it for free. Don't forget to clear the pending codes.

    DTC CHECK / CLEAR


    NOTICE:
    When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and freeze frame data recorded in normal mode are erased. Before changing modes, always check and make a note of DTCs
    and freeze frame data.

    HINT:
    • DTCs which are stored in the ECM can be displayed on the intelligent tester. The intelligent tester can display current and pending DTCs.
    • Some DTCs are not set if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.
    1. CHECK DTC
    (a) Connect the intelligent tester to the DLC3.
    (b) Turn the ignition switch to the ON position.
    (c) Turn the tester on.
    (d) Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
    (e) Check the DTC(s) and freeze frame data, and then
    write them down.
    (f) Check the details of the DTC(s).
    2. CLEAR DTC
    (a) Connect the intelligent tester to the DLC3.
    (b) Turn the ignition switch to the ON position.
    (c) Turn the tester on.
    (d) Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CLEAR CODES.
    (e) Press the YES button.
    3. CLEAR DTC (Without using the intelligent tester)
    (a) Perform either one of the following operations:
    (1) Disconnect the negative (-) battery cable for more than 1 minute.
    (2) Remove the EFI and ETCS fuses from the relay block located inside the engine compartment for more than 1 minute.

    NOTICE:
    When disconnecting the battery cable, perform the INITIALIZE procedure.
