Combination Meter - Diagnosis: Pre-Check

  1. CALIBRATE COMPASS 
    1. Set the zone.
      1. Deviation between the magnetic north and "actual north" differs depending on the terrestrial location, therefore, an adjustment in magnetism is required. Since the magnetic condition differs according to the area where the vehicle will be used, it is necessary for each user to set the zone. The zone setting can be changed using the RSET switch of the display.
    2. Perform the calibration.
      1. Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This compass function is used when storing the record of the vehicle's magnetic field.
    3. When compass magnetized:
      1. A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore, make sure to perform calibration and ensure that calibration can be done. If it cannot be done (cannot complete in spite of driving round several times), it may be caused by magnetization. Demagnetize the vehicle using a demagnetizer and perform calibration again.
    4. Set the compass.

    5. Zone setting mode.
      1. Turn the ignition switch to ON.
      2. Keep pressing the ODO/TRIP switch and RSET switch for 3 sec. when compass is displayed will activate the zone setting mode, showing a number (1 - 15) on the compass display.

        NOTE: In the initial status, "10" is displayed.
      3. The displayed number increases +1 every time the RSET switch is pressed. Referring to the map, check the number for the area where the vehicle will be used and set the zone number
    6. Calibration setting mode.
      1. After the set zone is displayed, if the TRIP switch pressed will activate the calibration setting mode.
      2. Drive the vehicle at a slow speed of 5 MPH (8 km/h) or less in the circular direction.
      3. Driving round the circle 1 to 3 times will display the azimuthal direction on the display, competing the calibration.
    NOTE: Once calibration is competed, it is not necessary to perform the above procedures unless the magnetic field strength is drastically changed.
  2. INSPECTION WITH OBDII SCAN TOOL OR LEXUS HAND-HELD TESTER 
    1. Read value of OBDII scan tool or LEXUS hand-held tester.
      1. Following the screen instructions of OBDII scan tool or LEXUS hand-held tester, activate the "DATA LIST" screen and check the computer data.
