2004 Toyota Matrix XR, FWD, StandardSECTION DTC Check/Clear
WARNING: This page is about a different car, the 2004 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • If no DTC appears in normal mode:

    On the OBD II scan tool or the hand held tester check the pending fault code using the Continuous Test Results function (Mode 7 for SAE J1979).

  • 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 will be erased. Before changing modes, always check and make a note of DTCs and freeze frame data.
  1. CHECK DTC (Using the OBD II scan tool or hand held tester) 
    1. Connect the OBD II scan tool or hand held tester to the DLC3.
    2. Turn the ignition switch ON.
    3. Use the OBD II scan tool or the hand held tester to check the DTCs and freeze frame data and then write them down.

      For the hand held tester, enter the following menus: DIAGNOSIS/ENHANCED OBD II/DTC INFO/CURRENT CODES. For the OBD II scan tool, see its instruction manual.

    4. See DIAGNOSTIC TROUBLE CODE CHART  to confirm the details of the DTCs.
    NOTE: When simulating a symptom with the OBD II scan tool (excluding hand held tester) to check for DTCs, use the normal mode. For DTCs subject to "2 trip detection logic", perform either of the following actions.
    • Turn the ignition switch OFF after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the MIL illuminates and the DTCs are recorded in the ECM.
    • Check the pending fault code using the Continuous Test Results function (Mode 7 for SAE J1979) on the OBD II scan tool.
  2. CLEAR DTC (Using the OBD II scan tool or hand held tester) 
    1. Connect the OBD II scan tool or the hand held tester to the DLC3.
    2. Turn the ignition switch ON.
    3. Erase DTCs and freeze frame data with the OBD II scan tool (complying with SAE J1978) or the hand held tester. For the hand held tester: 1) enter the following menus: DIAGNOSIS/ENHANCED OBD II/DTC INFO/CLEAR CODES; and 2) press YES. For the OBD II scan tool, see its instruction manual.
  3. CLEAR DTC (Not using the OBD II scan tool or handheld tester) 
    1. Remove the EFI and ETCS fuse from the engine room J/B for more than 60 seconds. Or, disconnect the battery terminal for more than 60 seconds.

      After disconnecting the battery terminal, perform the "INITIALIZE" procedure (see INITIALIZATION ).
