CONFIRMATION DRIVING PATTERN

NOTICE:
After turning ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work (YARIS_NCP93 RM000000UYX0BYX.html).
  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
  4. Turn the Techstream off.
  5. Turn the ignition switch off.
  6. Disconnect the Techstream.
  7. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
  8. Connect the cable to the negative (-) battery terminal.
  9. Connect the Techstream to the DLC3.
  10. Turn the ignition switch to ON and turn the Techstream on.
  11. Wait for 16 seconds or more.
  12. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
  13. Read pending DTCs.
    HINT:
    1. If a pending DTC is output, the system is malfunctioning.
    2. If a pending DTC is not output, perform the following procedure.
  14. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
  15. Input the DTC: P060A.
  16. Check the DTC judgment result.

    Techstream Display
    		Description
    NORMAL
    1. DTC judgment completed
    2. System normal
    ABNORMAL
    1. DTC judgment completed
    2. System abnormal
    INCOMPLETE
    1. DTC judgment not completed
    2. Perform driving pattern after confirming DTC enabling conditions
    N/A
    1. Unable to perform DTC judgment
    2. Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
    HINT:
    1. If the judgment result shows NORMAL, the system is normal.
    2. If the judgment result shows ABNORMAL, the system has a malfunction.
  17. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (YARIS_NCP93 RM000000PDK0QGX.html).
    HINT:
    1. If a permanent DTC is output, the system is malfunctioning.
    2. If no permanent DTC is output, the system is normal.
