2005 Toyota Matrix XR, FWD, StandardSECTION Diagnostic Trouble Codes Check/Clear
WARNING: This page is about a different variant/trim than selected.
NOTE: Hand held tester only: 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 a hand-held tester or OBD II scan tool. A hand-held 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 (Using a hand-held tester or OBD II scan tool) 
    1. Connect a hand-held tester or OBD II scan tool to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the tester or scan tool ON.
    4. If using a hand-held tester, select the following menu items: DIAGNOSIS/ENHANCED OBD II/DTC INFO/CURRENT CODES.
    5. If using an OBD II scan tool, refer to the instruction manual.
    6. Check the DTC (s) and freeze frame data, and then write them down.
    7. See DIAGNOSTIC TROUBLE CODE CHART  to check the details of the DTC (s).

    HINT:

    When simulating a symptom with an OBD II scan tool to check DTCs in the DIAGNOSTIC TROUBLE CODE CHART, subject to 2 trip detection logic, conduct either of the following operations. (For more information, refer to the scan tool instruction-manual.)

    • Check pending DTCs using the Continuous Test Result function (Mode 07 for SAE J1979).
    • Simulate the symptom again after turning the ignition switch to OFF upon finishing the first symptom simulation, so that the MIL is illuminated and the DTC (s) is stored in the ECM.
