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. When 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 he 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 (segmen
t
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.
RTW38DSF000101
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.

Low Fuel Indicator Light Inspection
1. Disconnect the fuel tank unit wire connector.
2. Turn the key switch on. Check that the bulb lights.
If operation is not correct, remove and check the bulb or circuit.
or If check whether low fuel turns on fuel input (B-24) at the
time of open and key on.
meter is check at low fuel
140R300006
Check level sensor operation
1. Remove the fuel tank unit.
2.
Apply battery voltage between terminal (B) and (C) through
a 1.12 watt bulb. Check that the bulb lights.
Note:
It will take a short time for the bulb light.
3. Submerge the sensor in fuel. Check that the bulb goes out.
If operation is not correct, replace the fuel tank unit.
BRAKE SYSTEM WARNING LIGHT
The brake system warning light comes on while the parking
brake is set and the engine run position.
Note:
The parking brake indicator light circuit is designed to
prevent driving of the vehicle with the parking brake on.
It does not indicate the condition of the parking brake
system.
The parking brake switch is in parallel with the brake fluid
switch.
The brake system warning light also comes on when reservoir
brake fluid level falls below the specified limit with the parking
brake released and the engine run position.
