Read Current Data For Engine (Normal Mode)

WARNING: This page is about a different car, the 2012 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
  1. On << Main Menu >> display, select {Each System Check}.
  2. On << System Selection Menu >> display, select {Engine Control System}.
  3. Click the [OK] button after the information of engine type has been displayed.
  4. On << Engine Diagnosis >> display, select {Current Data Display & Save}.
  5. On << Current Data Display & Save >> display, select {Normal sampling}.
  6. Using the scroll key, scroll the display screen up or down until the desired data is shown.
    • A list of the support data is shown in the following table.
