Tachometer On-Vehicle Inspection
1. Attach a tune-up tester to the engine.
2. Start the engine.
3. Compare the tachometer reading and the tester reading.
If the tachometer indication is outside the permissible range, the tachometer must be replaced.
4. Gradually increase and decrease the engine speed.
Note the movement of the tachometer needle.
If the needle movement is sluggish, the tachometer must be replaced.

Tachometer Off-Vehicle Inspection
Remove the tachometer from the meter assembly and
measure the resistance value and the current consumption
between each terminal.
SELF DIAGNOSTIC FUNCTION
Check that the speedometer, tachometer, fuel gauge, and
temperature gauge operate properly.
821R300033
Entering the self-diagnostic mode
1. Push in and hold the “Change Indicator and Reset” knob.
2. Turn the ignition ON.
3. W hen the LCD odometer turns ON, release the “Change Indicator and Reset” knob.
4. Push in and release the “Change Indicator and Reset” knob three times in quick succession.
The meter cluster is now in “Self-diagnostic” mode.
NOTE: Steps 2-4 must be performed within 7 seconds.
The meter cluster will not enter “Self-diagnostic” mode if any of
the following conditions occur:
1. The “Change Indicator and Reset” knob is not depressed when the ignition is turned ON.
2. The “Change Indicator and Reset” knob is released within 600ms of turning the ignition ON.
3. The “Change Indicator and Reset” knob is not depressed and released three times within 7 seconds.

Self –diagnostic mode
LCD condition
• All LCDs are lit during the transition from self-diagnostic
decision mode to self-diagnostic mode
• The odometer/trip indicator scrolls throng its entire range
approximately once every 600 ms. All digits are lit (segment
check indication). This continues until the self-diagnostic
mode is terminated.
Meter and gauge indications
Meter and gauge indications with the change indicator and
reset knob on (self-diagnostic mode) are as shown in the
following table.
RTW 78ASF000101
Speedometer 100 kilometers per hour
Tachometer 3,000 rpm
Fuel gauge
Temperature gauge Mid-point on the dial
All indications return to zero when the change indicator and
reset knob is turned off.
The self-diagnostic mode and the self-diagnostic decision
mode are cancelled when the ignition switch is turned to the
OFF position. They also cancel when a speed pulse is sensed.
If either of the self-diagnostic modes are cancelled by turning
the ignition switch to the OFF position, the diagnostic unit
remains in the stand-by condition.
If cancellation occurs when a speed pulse is sensed, the unit
remains in the ordinary operating condition.
