On Board Diagnosis Function
 
 
ON BOARD DIAGNOSIS ITEM
The following meter functions can be checked during combination meter self-diagnosis mode:
  • Pointer sweep of speedometer, tachometer and gauges.
  • Illumination of color patterns for meter displays.
  • Illumination of all lamps/LEDs that are controlled by the combination meter (regardless of switch status).
  • Error code
 
 
METHOD OF STARTING
 
 
How to Initiate Self-Diagnosis Mode
  1. Turn ignition switch OFF.
  2. While pressing the control switch , turn ignition switch ON.
  3. Keep pressing the control switch for 1 seconds or more.
  4. Press the control switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)
  5. “Work instruction code” is indicated in the top portion of information display and self-diagnosis is started.
    noteWhen on-board diagnosis does not start, check the following items and replace combination meter if the check results are normal.
  6. The mode switches in the order shown below each time the control switch is pressed.
    note
    • If the control switch is not operated for 20 seconds or more, the self-diagnosis mode is automatically cancelled.
    • The self-diagnosis mode is cancelled by turning the key switch OFF.
    • The self-diagnosis mode is cancelled by engine speed 170 rpm or more.
