NOTICE Do not drop the meter unit. Place the meter unit so that it faces upward. If the meter unit is left upside down or sideways for a long time or dropped, it will malfunction. Do not short each terminals.

Check 1: Meter Unit Primary Operation Check

• Using the auxiliary leads, the 12 V battery to the meter unit connector as follows.
  • Connect the battery positive (+) terminal to the terminal [4].
  • Connect the battery negative (-) terminal to the terminals [21].

• Connect the terminal [8] to the battery (+) terminal.

• Check the following items.
  • The speedometer and tachometer needles momentarily point their last readings and back to the minimum position.
  • All the LCD (Liquid Crystal Display) segments [A] go on for a few seconds.
  • The yellow fuel level warning indicator light (LED) [B], red battery voltage warning indicator light (LED) [C] and yellow oil service indicator light (LED) [D] go on for a few seconds.
  • For ABS equipped model, the yellow ABS indicator light (LED) [E] goes on.

  If the meter unit does not work, replace the meter unit.

Check 2: ADJ Button Operation Check

• Connect the leads in the same circuit as Check 1.

• By pushing the ADJ button [A] for 2 seconds, check that the display [B] changes as follows.

If the display function does not work, replace the meter unit.

Check 3: Clock Setting Check

• Connect the leads in the same circuit as Check 1.

• Set the ODO mode [A] by pushing the ADJ button [B] for 2 seconds.
• Push the MODE button [C] and ADJ button simultaneously for more than 2 seconds to adjust the clock [D].
  • The hour display only blinks.

• By pushing the ADJ button each time, check that the hour display [A] changes.

• By pushing the MODE button, check that the hour display decides and minute display [A] starts blinking.
• By pushing the ADJ button each time, check that the minute display changes.
• Push the MODE button and ADJ button simultaneously for more than 2 seconds. The displays stop blinking and the clock starts working.

  If the display function does not work, replace the meter unit.

Check 4: Green Turn Signal Indicator Light (LED) Inspection

• Connect the leads in the same circuit as Check 1.
• Connect the terminal [7] (right) or [9] (left) to the battery (+) terminal.

• Check that the green turn signal indicator light (LED) [A] goes on.

  If the indicator light (LED) does not go on, replace the meter unit.

Check 5: Blue High Beam Indicator Light (LED) Inspection

• Connect the leads in the same circuit as Check 1.
• Connect the terminal [5] to the battery (+) terminal.

• Check that the blue high beam indicator light (LED) [A] goes on.

  If the indicator light (LED) does not go on, replace the meter unit.

Check 6: Yellow Engine Warning Indicator Light (LED) Inspection

• Connect the leads in the same circuit as Check 1.
• Connect the terminal [19] to the battery (-) terminal.

• Check that the yellow engine warning indicator light (LED) [A] goes on.

  If the indicator light (LED) does not go on, replace the meter unit.

Check 7: Red Oil Pressure Warning Indictor Light (LED) Inspection

• Connect the leads in the same circuit as Check 1.
• Connect the terminal [1] to the battery (-) terminal.

• Check that the red oil pressure warning indicator light (LED) [A] goes on.

  If the indicator light (LED) does not go on, replace the meter unit.

Check 8: Speedometer Inspection

• Connect the leads in the same circuit as Check 1.
• The speed equivalent to the input frequency is indicated in the oscillator [A], if the square wave is input into terminal [20].
  • Indicates approximately 60 km/h if the input frequency is approximately 550 Hz.

  If the meter function does not work, replace the meter unit.

NOTE

• The input frequency of the oscillator adds the integrated value of the odometer.

Check 9: Odometer Check

• Check the odometer with the speedometer check in the same way.

  If value indicated in the odometer is not added, replace the meter unit.

Check 10: Trip A/Trip B Meter Check

• Check the trip meter with the speedometer in the same way.

  If value indicated in the trip meter is not added, replace the meter unit.

• Check that when the RESET button is pushed for more than 2 seconds, the figure display turns to 0.0.

  If the figure display does not indicate 0.0, replace the meter unit.

Check 11: Tachometer Inspection

• Connect the leads in the same circuit as Check 1.
• The engine speed (rpm) equivalent to the input frequency is indicated in the oscillator [A], if the square wave is input into terminal [13].
  • Indicates approximately 4 000 rpm if the input frequency is approximately 67 Hz.

  If the meter function does not work, replace the meter unit.

Check 12: Meter Illumination Light (LED) Inspection
