      HINT:
      1. A beep sound is emitted once when the DTC memory is completely cleared.
      2. When the DTC memory for all the components is cleared, only the component codes (physical addresses) are displayed.
      3. After the DTC memory is cleared, "Service Check Mode" is restored.

  2. Clearing Individual DTC Memory (when clearing the memory of the DTC previously detected individually)

    1. When preset switch "5" is pressed for 2 seconds or more during "Detailed Information Mode 1" or "Detailed Information Mode 2", the DTCs for the target component are cleared.

      HINT:
      1. A beep sound is emitted once when the DTC memory of the target component is completely cleared.
      2. When the DTC memory is cleared, only the component code (physical address) is displayed for the target component.
      3. After the DTC memory is cleared, "Service Check Mode" is restored.
      4. To check DTCs, press preset switch "1" and perform the system check again.

  3. Press preset switch "1" to perform the service check again, and check that no DTCs are displayed for all the component codes (physical addresses).
